4. Battery Performance
Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~85%.
Normal charge: Charge battery under CC(0.2C)/CV(57.6V) mode until over charge protection or the
charge current reduce to 0.02C, and then rest for 0.5h.
5. BMS function
This battery pack have Battery Management System (BMS), which can monitor the system operation state,
provide over discharge, overcharge, over current, short circuit, over temperature, low temperature protection. And
the BMS support communication between battery packs, and connect to external equipment.

After Normal charge,discharge @0.2C current to the end
Of discharge voltage. Repeat above process until
discharge capacity reduce to 80% of initial value.
0.5h, then discharge @0.2C current to 3.1V. Repeat
above process until discharge capacity reduce to 80% of
