Collection: LiFePO4 cells

Loose prismatic LiFePO4 cells: EVE at 3.2V 105Ah, also sold in fours to build a 12V 100Ah bank, and SUNWODA at 280Ah with 1.2C maximum discharge and 314Ah with 1C, all genuine with traceable batch.

What distinguishes one cell from another is not only capacity but discharge rate: a 280Ah at 1.2C can deliver around 336A continuous, a 314Ah at 1C around 314A. That figure, not the Ah, defines the finished pack's power and therefore which inverter you can connect.

A 12V bank takes 4 cells in series, 24V takes 8, 48V takes 16. Choose the BMS on pack current and on the number of cells in series.
