Collection: Lithium cells

Loose cells for building or repairing battery packs: genuine EVE prismatic LiFePO4 cells at 3.2V 105Ah and 280Ah, also sold in sets of four to make a 12V pack, and cylindrical Li-ion 18650 and 21700 cells from EVE and HAKADI, 1500mAh to 4800mAh with discharge up to 30A.

On prismatic LiFePO4 what counts is capacity, cell grade and batch consistency: cells that differ in voltage and internal resistance will not stay balanced. On cylindrical Li-ion the figure that decides it is continuous maximum discharge current, far more than nominal capacity.

Every cell is genuine and traceable. A proper BMS is always needed: bare cells have no built-in protection.
