38140S 12Ah lifepo4 battery are the cylindrical EV batteries (38mm x 140mm)10S2P means 2 parallels with 10 in series each (20 cells total)20C/30C means maximum constant discharge rate/Burst discharge rate (<10sec) (for LiFePO there is just one C rating)When combining batteries, the participating batteries must all be identical in voltage and capacity.

• Lower energy density• Still expensive• Cell imbalance during charging
• Thermal runaways• Catastrophic field-failures• Lithium-intensive
• Fast/powerful• Rugged/durable• Stable/reversible• Long-lived• Safer• Cost-effective
• Low voltage drop under load• Predictable end of life• Thermally stable to 300oC• Non-explosive• No oxygen emission
