This is a 51.2V 50Ah (2,560Wh) power-type battery pack built with 16S LiFePO₄ cells. It supports up to 3,840W of continuous output and a maximum discharge current of 75A, and retains at least 60% of its nominal capacity even after 2,500 cycles.
It has a built-in MOSFET-controlled BMS providing overcharge, over-discharge and overcurrent cutoff, short-circuit protection, over-temperature cutoff and cell balancing.
These specifications are based on product specification sheet DM-PWR-51.2V-50Ah. The charge/discharge switch (ON/OFF) and the AC charger are optional.
