Always match polarities on the chargeleads and banana jacks (red, positive (+) lead to red banana jack, black, negative (-) lead to the black banana jack. WARNING!Never allow a batterys positive and negative leads to accidentally touch each other. This will result in a short circuitand cause permanent damage to your battery and/or charger.

DETERMINING BATTERY TYPE AND SPECIFICATIONS

IMPORTANT: What is your batterys CHEMISTRY TYPE, RATED CAPACITY, AND RATED VOLTAGE? To avoid causingpermanent damage to your battery, carefully read your batterys label and/or instruction sheet or consult your battery supplierand determine:

1. Type: Is the battery a nickel-metal hydride (NiMH), nickel-cadmium (NiCd), lithium-polymer (LiPo), or lithium-ion (Li-Ion)?

2. Rated capacity: The amount of charge energy the battery can store should be listed on the batterys label as mAh (milli-amp hours). Capacity is also referred to as the C rating. Charge and discharge currents are also expressed as a functionof this C rating. For example, a 4200mAh battery would have a 1C charge or discharge current rate of 4200mA or 4.2 amps.This batterys 2C rating would be (4.2 x 2) 8.4 amps, etc.

3. Rated voltage: If not printed on the batterys outer label, consult your battery supplier or determine pack voltage as follows:

A. NiMH and NiCd batteries: multiply the total number of cells in the pack by 1.20. A 6-cell pack will have a nominalvoltage of 7.20 volts (6 x 1.20). A 4-cell pack will have a nominal voltage of 4.80 volts (4 x 1.20), etc.

B. LiPo batteries: multiply the total number of cells in the pack by 3.70. A 2-cell pack wired in series will have anominal voltage of 7.4 volts (2 x 3.70), etc.

C. Li-Ion batteries: multiply the total number of cells in the pack by 3.60. A 2-cell pack wired in series will have anominal voltage of 7.20 volts (2 x 3.60), etc.

DC INPUT POWERTo utilize the chargers absolute maximum power capabilities the DC power source must be capable of delivering at least 15amps of current while maintaining 12 volts DC. The charger will be on at all times when connected to input power. Disconnectthe charger from input power when not in use. There are two ways to connect the charger to input power:

1. Connect the banana plugs on the chargers input cord directly to banana jacks on a DC power supply. Always matchpolarities (red lead to red banana jack, black lead to black banana jack).

WARNING! Never accidentally short together the positive (+) and negative (-) input connections when connected to12V DC power. Failure to do so could result in permanent damage to the power source and the charger. Itsrecommended to disconnect the charger from input power when not in use.

GETTING STARTED SELECTING A MEMORYThere are three main ways to setup and begin using this charger:

A. Select one of the factory pre-programmed memories to handle your battery: The ten memories are factory pre-programmed for different battery types, charge and discharge currents, etc., as shown in the included battery memory chart.If your battery and charge/discharge needs match any of the pre-programmed memories, simply select that memory number[0-9] on the top line of the Main Memory as shown below. You can also set a name for any memory as shown below.

B. Customize a memory to match your batterys specifications: If your battery and charge/discharge needs do not exactlymatch any of the pre-programmed memories, you can customize the settings in any memory as you wish (described in thenext section). Battery memories will hold data until changed again manually. Use the included blank chart to record your owncustomized memory settings. You can set a name for any memory as described below.

C. If you do not wish to use a memory, simply alter the settings in the default memory screen as needed to charge,discharge, or cycle a battery as described in the next section.

To RESET every setting for all memories back to the factory defaults, first disconnect the charger from power. Press and holdboth the! and" buttons, and then re-connect the input leads to power. An initialization screen will appear, then the MainMemory screen will show at which time all memory settings will be CLEARED and returned to the factory defaults. Do NOTperform this reset if you do not wish to clear all settings in the memory!

ADJUSTING MAIN FUNCTIONSWhile in a memory screen, rotate the dial to move the cursor up or down. Press the dial to highlight the adjustable value onany line. Rotate the dial to adjust the highlighted value. Re-press the dial to set the selection into memory. Design informationand recommendations for some settings are included in the boxed-in notes at the end of this section.

2. Charge current: Move the cursor down to the chg current line. Press the dial, then rotate to find the desired chargecurrent. Re-press dial to confirm setting.

3. Discharge current: Move the cursor to the dchg current line. Press the dial, then rotate to find the desired dischargecurrent. Re-press dial to confirm the setting. If current is set to 10A or less, current will be drained from the battery in a 100%linear configuration.

The TC-1030 also offers unique non-linear discharge currents of 20A and 30A for NiCd and NiMH packs only. Here, the batteryis discharged for 2 seconds at the selected current, then discharge is paused for 4 seconds. This process is repeated until thebattery reaches discharge cutoff. These settings are for conditioning of competition level racing packs, to lower a batterys

internal resistance and improve the batterys average discharge voltage. These settings are NOT functional with NiCd/MHbatteries having more than 6 cells. Refer to the notes at the end of this section for more details.

4. Peak sensitivity (NiCd and NiMH batteries only): This feature determines the accuracy of the peak detection circuit. Theadjustable range for NiCd batteries is 5-25mV (8-10mV is recommended). For NiMH batteries the range is fully adjustable from0mV (ZEROpk) to 15mV. Some racers prefer 1mV or 2mV settings. See the notes section for further details.

5. Discharge cutoff voltage: This is NOT the discharge cutoff voltage for the ENTIRE pack. Instead, set the voltage levelfor EACH CELL in the pack where discharge will stop. See the notes section for more details.

6. Trickle charge current (NiCd and NiMH batteries only): This is the amount of trickle charge current that will be appliedto the battery only after peak charge has ended (not after discharge or cycling). See the notes section for further details.

7. Cutoff temperature: When used with the optional Team Checkpoint Temperature Sensor (TCPP9101), this charger canmonitor the temperature of the battery connected at the outputs. Monitoring a batterys temperature in addition to its voltagecan allow the charger to provide the most accurate full charges without damaging the battery, and is STRONGLYrecommended for use with LiPo/Ion batteries. Refer to the notes that follow for details how to use this function. Otherwise,skip to #8.

8. Number of cycles (NiCd and NiMH batteries only): This is the number of times the charger will automatically perform acharge-to-discharge or discharge-to-charge cycle. See Cycle Mode below for how to set which function to perform first.

9. Cycle delay (NiCd and NiMH batteries only): This is a time delay that will occur between charge and discharge duringa cycle, designed to allow the battery to cool.

10. Cycle mode (NiCd and NiMH batteries only): This sets the pattern in which cycles are performed. Select either tocharge the battery before discharge (C>D), or to discharge before charge (D>C).

11. Maximum charge capacity: If the charger fails to detect full charge, this setting will automatically stop the charge processwhen a certain amount of energy has been delivered to the battery. Instead of setting an actual capacity value, set the percentof full capacity. For example: if the battery capacity entered in 1.c. on page 5 was 4200 and if the value set in this screen is110%, charge will stop automatically when (4200 x 110%) 4620mAh is delivered to the battery. For LiPo/Ion batteries therecommended maximum value is 105-110%. A secondary use for this feature is to prepare batteries for extended-termstorage. Cell manufacturers recommend applying a partial charge to batteries before being put in storage. For such uses, itsrecommended to set this value to 30% for NiCd/MH batteries, and to 10% for LiPo/Ion batteries.

Do not connect a sensor to the charger if you do not wish to use the sensor. See the User Setup Menu to change the temperature scale between Celsius and Fahrenheit. The maximum recommended temperature for NiCd batteries is 113-130

o

F (45-55o

C). The maximum recommended temperature for NiMH batteries is 110-125

o

F (43-52o

C). NiCd and NiMH cells which are AAA size or smaller should use lower temperatures. For best results, start with lower

temperatures first, then if needed adjust this value upwards in small increments and closely monitor the charge progress. For LiPo/Ion batteries, exercise great caution! The maximum temperature for LiPo/Ion cells should not exceed 90-95

o

F(32-35

o

C). Start with lower temperatures first and if necessary adjust the temperature setting as needed in smallincrements and closely monitor the charge progress.

If the battery reaches the max. temperature setting during charge, the charge process will completely stop and will notre-start. Setting the temperature value too low may cause the charge process to stop too early, before full charge hasoccurred. If so, increase the temperature setting by a small amount, making sure not to allow the battery to overheat.Setting the temperature value too high may cause the battery to overheat. If so, decrease the temperature setting.

If the battery reaches the max. temperature setting during discharge, discharge will temporarily pause to allow thebattery to cool to a safe temperature. Discharge will automatically resume when the batterys temperature drops by about4

o

F (2o

C).

7/26

12. Peak delay (NiCd and NiMH batteries only): This temporarily de-activates the peak detection circuit only at thebeginning of charge when a batterys voltage might be unstable, to prevent the charger from accidentally shutting down chargetoo early. Usually, a batterys voltage will stabilize in a very short period of time, after which the peak detection circuit can bere-activated. Set the number of minutes after charge has begun for the peak detection circuitry to start looking for peak.

13. Top-off charge: For NiMH batteries, when peak charge ends, applying a short top-off charge current can help to morefully charge the battery before trickle charge begins. Top-off charge current is typically higher than trickle charge current. Therecommended top-off current should not exceed 20% of the packs rated capacity. So, a battery rated at 3300mAh should havea top-off current setting of no greater than (3300 x 20%) 660mA.

STARTING CHARGE, DISCHARGE OR CYCLEDifferent methods and miscellaneous functions are available for charging or discharging batteries. If you wish to learn aboutall such features, read this section entirely. Otherwise, to start charge, discharge, or cycle using the factory default methodssee the diagram below.

2. Rotate the dial to place the

cursor next to the correct function.

Press and hold the dial for 2

seconds to start the function.

Notes for settings in the Main Memory screen: If a NiCd or NiMH battery does not achieve a true peak, the charger will shut down automatically if the battery reaches

2.0V per cell and the high voltage error will show. The maximum charge voltage for LiPo cells is 4.20V, and 4.10V for lithium-ion cells. The maximum charge current applied to LiPo/Ion batteries is automatically limited to their 2C value. The maximum discharge current value for LiPo/Ion batteries will be limited to their 2C value. When using the 20A or 30A discharge current settings for NiCd/MH batteries, the discharge TIME will only be tracked

during the 2 seconds current is drained from the battery (ignored during the 4 second pauses). The length of these pulsesare long enough that they do NOT harm NiMH cells. Here the graphing display will update data every second. A batteryvoltage too high error will occur if the battery voltage exceeds 9.6V. As opposed to very quick discharge pulses in somechargers, this customized process does not harm NiMH batteries.

Properly setting the peak sensitivity feature to the charge characteristics of a battery can help to achieve better peak

charges. Lower numbers usually result in more precise peak detection, but in certain situations could cause the chargerto errantly stop peak charge too early. In such cases, increasing this value (8mV or greater for NiCd, 5mV or higher forNiMH) may be necessary - especially if using an external AC power supply on the input.

Some NiCd and NiMH cell manufacturers rate the capacity of their batteries based on a discharge cutoff voltage of 0.9Vper cell. So, to see if the battery is supplying the amount of capacity as rated by the manufacturer, set the dischargecutoff voltage to 0.8 or 0.9V. This is also a good voltage for stopping discharge of sub-C size cells to determine theiruseful run-time in minutes. However, for any A, AA or sub-C size cells that are used to power radio transmitters orreceivers, to find the most realistic run-time set the discharge cutoff voltage to 1.1V per cell. Most R/C receivers are notcapable of maintaining control with a 4-cell NiCd/MH battery that is discharged below 1.1V per cell.

For LiPo/Ion batteries, a discharge cutoff voltage setting of 2.8 3.0V is recommended. Trickle charge current range is 0-500mA. If charging A or AA size Tx or Rx batteries, it is not recommended to set the

trickle current to larger than 50mA. For sub-C batteries, the recommended trickle current setting is roughly C/20 (battery

capacity divided by 20). If fast charge is paused because the battery reached the max. temperature setting, trickle charge will not begin until

battery temperature drops about 4o

F (2o

C) below the max. temperature setting. Top-off charge will automatically begin 5 minutes after peak charge has ended (in normal and reflex charge modes only, not for

automatic, impulse, 3-step or four-step charge modes). Top-off charge stops automatically after 20 minutes. If the batterys voltagepeaks or its temperature reaches the maximum setting before the timer expires, top-off charge will end automatically.

NiCd AND NiMH PEAK CHARGE METHODSFour different methods are available for peak charging NiCd and NiMH batteries: automatic, normal, re-flex, and re-peak.Selecting any of these methods is done in the start screen shown at the bottom of page 7. When the cursor is next toCHARGE, press the dial briefly to cause the word to the right in brackets to highlight. Then, rotate the dial to select one ofthe optional peak charge modes as described below. Once the desired peak charge mode is selected, re-press the dial toconfirm the selection.

1. NORMAL charge mode: 100% linear current is delivered to the battery. Note that a reserve time feature will show atthe bottom of the screen, which is a way to schedule the charger to finish charging a battery just prior to the start of a race.Refer to the Reserve Time Function section below if you wish to use this feature. Otherwise, to START CHARGE press and

to FINISH charging a battery just in time to cool off immediately before the start of a race.

As shown at right, the number inside the parenthesis is the "expect" time - the number of

minutes the TC-1030 calculates as being needed to fully charge the battery (based on

charge current and battery capacity values entered). The number on the right is the

"reserve" time - the number of minutes from now that you want charge to be finished.

RESERVE TIME FUNCTION

It may take some practice to get this function to work

as desired. To maximize the effectiveness of the reserve

time function, the "capacity" setting in the main menu may

need to be set to the most realistic possible maximum

capacity for your battery - as opposed to the pack's actual

rated capacity. For example, if your 4200mAh battery pack

can regularly accept a charge of up to, say, 4304mAh, you

should set the capacity value in the Main Memory screen to

4400mAh.

For example: If the next race starts in 75 minutes and you

want the battery to cool for at least 10 minutes before

starting the race, that leaves (75-10) 65 minutes to charge

the battery. If the charger calculated 42 minutes "(042m)"

are necessary to fully charge the battery, then set the

2. RE-FLEX charge mode: As shown at right, almost 100% linear current isdelivered to the battery, except for very quick, deep discharge pulses once persecond. Re-flex is believed by some to help remove oxidizing gas bubbles froma cells internal plates, allowing the battery to charge more efficiently. Re-flex isthought to be especially helpful for older NiCd batteries, but might not berecommended by some NiMH battery manufacturers. The Reserve Timefunction is also available in re-flex charge mode. See below for how to use thisfunction. Otherwise, to START CHARGE press and hold the dial for 2 seconds.

3. RE-PEAKcharge mode: With this feature, once the charger has finished peak charging a battery it can automatically re-chargethe battery to peak once or twice more as selected. This helps to ensure the battery is fully charged before a race. The charger willalso track how much additional capacity was added during each re-peak charge. Refer to the section below for full details on how touse this feature. A good battery should have low charge capacity values for any re-peak charges. Batteries having higher capacityvalues for the re-peak charges are not likely holding charge as well. A five minute cool-off delay occurs after each re-peak charge.Top-off charge is not available for NiMH batteries when using the re-peak charge mode.

4. AUTOMATIC charge mode: In this mode, the charger can detect the condition of the battery which is connected andautomatically charge it as needed. IMPORTANT!! Make sure the proper battery type and temperature settings areentered before starting auto charge! This feature can be handy if unsure of the specifications of your battery, but using thenormal charge mode will likely yield better results. In this mode, peak sensitivity is pre-set to 5mV for a NiCd battery, and4mV for NiMH. To START CHARGE, press and hold the dial for 2 seconds.

LiPo AND Li-Ion BATTERY CHARGE METHODSThe only method this charger uses for lithium-polymer or lithium-ion batteries is the cc/cv or constant current / constantvoltage process. This method is totally different than any method which is used for NiCd and NiMH batteries.

Constant current will be delivered to the battery in the beginning, at roughly the same value which was set in the Main Memoryscreen (actual current might be lower if the charger determines the battery is not in suitable condition to receive the full currentsetting). When LiPo batteries reach 4.20V per cell, or Li-Ions reach 4.10V per cell, the charger will automatically stopdelivering constant current, and start applying constant voltage. It is normal to see a considerable change in outputcurrent part-way through charge. This is because the charger will no longer be forcing a pre-set current to the battery, butinstead be applying a pre-set voltage to the battery. Here, the batterys voltage will gradually attempt to become equalized withthe voltage at the output of the charger. As the battery becomes more fully charged it will request less and less current fromthe charger. Once actual current to the battery drops to approx. 80-100mA, the charger will beep to indicate that fast chargehas finished. The charger will then automatically start a unique LiPo trickle charge current, indicated by Trk. flashing on thecurrent line as shown on the screen above-right. This trickle function will stop when current drops to approx. 30mA.

It is STRONGLY recommended to use an optional temperature sensor when charging LiPo/Ion batteries, as these batterytypes quickly reach failure mode immediately upon generating heat. Refer to the Cutoff temperature feature underADJUSTING SETTINGS IN A MEMORY on page 6 for full details.

DISCHARGE METHODSSelecting a discharge method is also done in the start screen as shown to the right. Rotate the dial to place the cursor nextto D-CHARGE. The discharge method (normal or automatic) will be shown in the brackets to the right. To change thedischarge method, press the dial, then rotate to find the desired method. Press the dial to confirm the selection.

A DEADSHORT discharge mode can also be selected for NiCd and NiMH batteries. This is a way to deeply discharge abattery below 0.8V per cell at greater than 5 amps. WARNING! If you are not sure about deep discharging your batteries,

do NOT use DeadShort mode! Dead-short mode is recommended only for very experienced racers. Some batterymanufacturers might recommend NOT deep discharging their cells as it could cause permanent damage (such as shortenedrun-time). Consult with your supplier if unsure if your batteries can handle DeadShort discharge mode. Refer to the diagramsthat follow to use Dead-Short discharge mode.

TO START DISCHARGE, make sure the cursor is next to D-CHARGE and press and hold the dial for 2 seconds. Press!anytime to manually stop discharge mode.

The NORMAL discharge method can be used with any battery type, and is

guided by all user settings in the Main Memory screen. Discharge current islinear, and cutoff voltages are those which are set manually.

The AUTOMATIC discharge method can only be used with NiCd and NiMHbatteries. Here, most user settings in the Main Memory screen are ignored.Instead, the charger automatically sets the discharge current based on thecondition of the battery, and cutoff voltage is pre-set to 0.8V per cell. The automode is convenient, but the charger will likely yield better discharge results if thenormal discharge method is used.

Notes for settings in the Data View screen:

Battery resistance measurements will start 2 minutes after discharge has stopped, and is shown in milli-ohms ( ).Battery resistance will not be measured if a NiCd/MH cell is below 1.0V, or if a LiPo/Ion cell is below 3.0V, as the

best time to judge a batterys internal resistance is when it is closer to full charge. A lower resistance value means

the charger can likely condition the battery more efficiently and accurately. A battery whose internal resistance

gradually worsens is likely showing the signs of aging and may soon need to be replaced. Internal resistance can

be greatly affected by the quality of the connection between the battery and charger.

Charge time doesnt include when a battery is in trickle charge or top-off charge.

For NiCd/MH batteries, the full graph should show in a single LCD frame. For lithium batteries, the total graphperiod is designed for a maximum of 3 hours based on a 1C rate (data past 3 hours wont be displayed). When

using the automatic charge or discharge mode, the overall graph period will be 2 hours maximum.

4-STEP CHARGE FOR NIMH BATTERIES

WARNING! NEVER USE THIS FEATURE WITH LiPo OR Li-Ion BATTERIES AS SEVERE, PERMANENT DAMAGE TO THEBATTERY AND ITS SURROUNDINGS WILL RESULT!! This feature is recommended for use by experienced users only.If set improperly, this feature can cause severe, permanent damage to a battery. If unsure about how to use thisfunction, do not use it.

This feature is designed for high performance NiMH batteries for racing. It can be used on NiCd batteries, but only if the peaksensitivity value is set properly as described below. The true advantage of this function is to deliver as much energy to thebattery as possible for racing punch yet allow for the most accurate peak detection as possible for maximum run-time, withoutdamaging the battery as a result of overheating.

Functions in the Four-Step screen are totally independent from the settings in the Main Memory screens. So all options in theFour-Step screen shown below must be set properly if using this charge method. A temperature sensor MUST be used inFour-Step Charge mode, otherwise this function will not operate.

Cycling can help to determine a batterys ability to store its maximum rated capacity. If abattery can only store a small fraction of its rated capacity its likely reaching the end ofits useful life and may need to be replaced. Cycling NiCds once monthly can helpmaximum the overall performance of the cells. NiMH batteries benefit much less fromcycling. New batteries, or older batteries which have not been used or cycled frequentlymay need to be broken-in before they will perform to their rated capacity.

Comparing how much energy that was delivered to a battery during charge vs. the

amount of capacity taken from the battery during a discharge thereafter can help todetermine how well the battery was able to hold charge. Comparing a batterysmeasured discharge capacity to its rated capacity is also an indication of the batterysgeneral condition. If a fully charged battery provides less than 70% of its ratedcapacity it may no longer be near the end of its useful life. Additional cycles can beattempted to try and increase the batterys storage capacity further, but if repeatedattempts fail to improve performance the batteries should be replaced.

Setting Four-Step Charge1. Press" to find the Four-Step screen shown above-right.

2. The cursor will show next to the second line on the LCD. All settings on this line must be set to match the battery beingcharged. Press the dial to highlight the number of cells, and rotate dial to adjust this value. To change peak sensitivity ormaximum temperature values, press" to highlight either of these selections. Rotate dial to adjust the settings as needed.Press the dial to confirm all settings for this line.

3. Rotate the dial to move the cursor down to the capacity line (just under the graph). Four different capacity values areshown, each being the maximum capacity that will be delivered to the battery during each of the four steps. Thecapacity value for each step must be set:

a. Press dial to highlight the capacity value for step #1. Rotate dial to adjust this capacity value as needed.b. Press" to select the capacity for steps 2, 3, and 4, and set the capacity for each step accordingly.c. Press dial to confirm all capacity settings.

4. Rotate the dial to move the cursor to the bottom line, which shows the four different charge current values which will bedelivered to the battery during each of the four steps. You must set the charge current value for each step:

a. Press dial to highlight the current value for step #1. Rotate dial to adjust this capacity value as needed.b. Press" to select the currents for steps 2, 3, and 4, and set the current for each step accordingly.c. Press dial to confirm all capacity settings.

In step 1, its important to stabilize the condition of the battery, so a conservative charge current should be set. Once thebattery is stabile and well into the charge process, much higher current can be delivered in step 2. The high current in step 2may eventually heat the battery, so current in step 3 should be reduced. Lastly, its best to reduce current in step 4 to againstabilize the battery for the most accurate peak detection (fullest charge). Remember that the peak detection circuitfunctions ONLY in step 4 (not steps 1-3).

During charge, the charger automatically moves from one step to the next once the capacity setting for each respective step hasbeen delivered to the battery. Be careful not to set the capacity value too high - especially in steps 2 and 3 where the current settingsare higher. The higher the capacity setting for any step, the longer that current will be applied to the battery during that step, and themore likely the battery might overheat causing the temperature sensor to trip and stop fast charge completely.

Step 2 - Delivering Punch:

1. Set capacity to 50-75%

of pack's rated capacity.

2. Set a higher current, up

to the battery's 2C rating todeliver "punch" for racing.

See the following examples for an idea of how one might set current and capacity settings for a 4200mAh battery and 1200mAhNiMH battery. It may take some practice and careful attention to customize the settings in this function to match your battery.

Expect and reserve times: these two lines work together to provide the Reserve Time Function as described earlier inthis manual. Again, think of this as a way to schedule when the charger should start charging the battery immediately beforea race.

When the capacity and charge current values are entered in the Four-Step charge screens, the charger will calculate how

much time will be expected to reach maximum capacity in step 4 - based on the charge current settings. This time will beshown on the expect time line.

The reserv time should be set to take into account the displayed expect time, plus how many minutes you want the batteryto cool immediately just before the start of a race. If set properly, the cool-down time will end only minutes before the racestarts, so that your pack is at peak race readiness. You cannot set a reserve time which is shorter than the expect time.The reserve time will not include the time needed for discharge-before-charge as explained below.

Trickle charge: This sets the trickle charge current that will be applied to the battery only after the fourth charge step ends.

Discharge > charge: This discharge-before-charge feature automatically discharges the battery before charge begins. This feature

is simply turned on, or off. It might be best to set this to on to empty the battery before starting the four-step charge mode.

Re-flex charge: Re-flex charge can also be applied at ANY of the first 3 steps, but not step 4. In addition, re-flex and impulsecharge can be applied to the battery at the same time. See the diagram below for how to set this function.

Impulse charge: This charge method can be thought of as the

opposite of the re-flex charge method. Instead of applying very

short, high level discharge pulses, impulse charge applies short,

high level charge pulses, equal to the charge current setting x 1.5,

for 0.5 seconds, every 3 seconds. Charge current at all other

times is as set in the Four-Step Charge screen. This method is

also thought to help clear oxidizing gas bubbles from a cell's

internal plates, allowing it to perform better. Impulse charge can

be applied during ANY of the first 3 steps in the charge process,

but not step 4. See the diagram below for how to set this function.

Temperature check: A temperature sensor MUST be used with Four-Step charge mode, or charge will not begin. The temperaturesensor can be set to function in any of the first 3 steps, but will automatically be active during the fourth step. See the diagram belowfor how to set this function.

3-STEP CHARGE FOR NIMH BATTERIES

To START 3-STEP CHARGE, press and hold the dial for 2 seconds.

CARE & HANDLING OF NIMH BATTERIES Do not to allow NiMH batteries to overheat! Disconnect overheated batteries from the charger immediately and allow to cool.

Do not attempt to use the chargers LiPo/Ion functions with NiMH batteries. NiMH cells do not exhibit a memory effect, so little cycling is needed. Store NiMH packs with some voltage remaining on the cells (refer to battery supplier). It is important to recharge NiMH batteries immediately prior to use, as they have a self-discharge rate of approximately 20-25%. N, AAA, AA and A size radio batteries can safely be peak charged at currents up to 1.5C to 2C (battery capacity x 1.5

or 2.0). High charge currents can overheat batteries and thus reduce service life, especially for smaller size cells.

CARE & HANDLING OF LITHIUM-POLYMER AND LITHIUM-ION BATTERIES

DO NOT try to charge lithium-polymer (LiPo) or lithium-ion (Li-Ion) cells in the same way as other battery types! Always readthe instructions that are included with your lithium batteries carefully before use. Failure to follow these care and handling instructionscan quickly result in severe, permanent damage to the batteries and its surroundings and even start a FIRE!

ALWAYS charge lithium batteries in a fireproof location, which could be a container made of metal or ceramic tile. Monitorthe area with a smoke or fire alarm, and have a lithium approved ABC type fire extinguisher available at all times.

ALWAYS provide adequate ventilation around LiPo/Ion batteries during charge, discharge, while in use, and during storage. DO NOT allow LiPo or Li-Ion cells to overheat at any time, as they can and usually will become physically damaged and

could possibly EXPLODE or catch FIRE!! If a battery becomes overheated, disconnect it from the charger IMMEDIATELY! DO NOT continue to charge LiPo or Li-Ion batteries if the charger fails to recognize full charge. Swelling of LiPo cells is an

indication that they are in an overcharge condition and they should be disconnected from the charger immediately. DO NOT set the chargers LiPo/Ion battery voltage settings to a voltage that is HIGHER than the nominal rating of the battery

itself, as such cells cannot handle overcharging in any way. DO NOT charge LiPo or Li-Ion batteries at currents greater than the 1C rating of the battery. DO NOT discharge LiPo or Li-Ion batteries at currents which exceed the discharge current rating of the battery, as this can

often cause a cell to overheat.

DO NOT allow LiPo cells to come in contact with moisture or water at any time. DO NOT allow the internal electrolyte from LiPo or Li-Ion batteries to get in the eyes or on skin wash affected areas

immediately if they come in contact with the electrolyte and contact your physician! DO NOT attempt to use the chargers NiCd and NiMH functions for LiPo or Li-Ion batteries. ALWAYS store LiPo cells/packs in a secure location away from children.

3-Step Charge is sometimes preferred by

racers instead of 4-Step, and is easily

acheived by using the same screens as

4-Step mode but changing the settings.

As shown at right and below, what is

normally "step3" will effectively become

part of step2, and thus step4 will now

become step3.

Step 1:

1. Set the capacity value to 33-50%


2. Set a conservative current, slightly

under the pack's 1C rating.

Step 2:

1. Set capacity for both steps to be exactly the

same...75-100% of pack's rated capacity.

2. Set current for both steps to be exactly the

same...a higher value, up to the battery's 2C

rating to deliver "punch" for racing.

(These two steps will effectively function as one.)

ERROR MESSAGES AND TROUBLESHOOTING GUIDEThis charger offers protection against damage which could be caused by short-circuit or reverse polarity conditions, etc. Thelist of error messages is as follows:

Input voltage - The present input voltage is xx.xxV. Pls check the input voltage. The input voltage must be 11V~15V.No battery - A battery is not connected to the output. Please connect the battery to the output then restart!Reverse polarity - A battery is connected to the output in reverse! Pls correctly connect the battery to the output.Open circuit - A battery is disconnected during an operation. Pls reconnect the battery and restart!Short-circuit - Output short-circuited. Pls check the output. Note: When short circuit occurs on the output the chargerwill try to continue charge for 2 minutes. Sometimes cells which have previously been completely discharged (after a race,

with a cell discharger, etc.) might have such a low voltage that it appears to the charger that a short circuited exists at theoutput when really there is not. If a fully discharged cell is connected, its voltage will quickly rise when charge is applied andcharge will continue as normal. However, if the output is truly short circuited the voltage on the output will never increase andafter 2 minutes the charger will stop charge and display this message.

Low output voltage - Output voltage is lower than the selected cells or voltages. Pls select proper cells or voltages.Either the chargers voltage setting is incorrect, or the batterys rated voltage exceeds the setting.

High output voltage - Output voltage is higher than the selected cells or voltages. Pls select proper cells orvoltages. Either the chargers voltage setting is incorrect, or the battery is in poor condition.No motor - A motor is not connected to the output. Please connect the motor to the output.Motor disconnection - A motor has become disconnected during an operation. Pls reconnect the motor and restart!Sensor Connection - A temp sensor must be used in 4 step mode. Connect TCPP9101 temp sensor.Temperature sensor - A temperature sensor is connected in reverse or is defective.

Bat. Temp too low - Battery temp is too low to be operated! This message will show if the battery temperature is lowerthan 32oF during an operation, or lower than 14oF when in idle mode. If so, allow battery to warm before proceeding.Bat. Temp too high - Battery temp is too high to be operated! If this shows, let the battery to cool before proceeding.Pressing! will clear this message.

Charger too hot! Pls wait until the charger cools! This message will show when the chargers own internal temperaturereaches 212F (100C). Operations will temporarily pause, then automatically resume when internal temp. returns to below158F (70C). This protects the chargers electronics from damage due to excess heat.

Data communication - Something is wrong with the internal circuit. Contact Hobby Services This message will showif the chargers own logic experiences control problems. Contact Hobby Services if this occurs.

Other possible problems:

PROBLEM - LCD does not work when unit is connected to input power: Check power supply for improper power. Check input
