Headway 15Ah LiFePO4 Cylindrical Lithium Ion Battery, Used/Tested

These Headway LFP cells are an excellent option in demanding applications such as e-bikes, scooters and even EVs. With an extremely low internal resistance, they're capable of 10C(!) discharge. That's 150 amps, wow! We test all used cells for capacity, internal resistance and voltage prior to shipping. These will be at nominal voltage (3.2v for LiFePO4, 3.6v for li-ion) and require full charge prior to operation.  These have tested at greater than 95% capacity at 20a discharge.  Price is per cell, which includes fasteners, bus bar and plastic bracket.
