EPS offers matching chargers for 8, 12, 16, 20, 24 and 28 cell Li-ion battery packs. All our chargers use a 3-step charging program: constant current, constant voltage and pulsed charging steps. Together with balancers or BMS systems, they prevent over-charging conditions for Li-ion batteries. The chargers provide protections against overload, over-voltage, over-heat, short circuit and reverse polarity connection. Input AC voltage is 110V, and the output DC current is 15A or 20A.
