3. Electrical Characteristics & Test Condition


Testing Conditions: Ambient Temperature: 25±5℃ (68℉~86℉); Huminity:45%~75%.

Normal charge:Charge battery under CC(0.33C)/CV(58.4V) mode until over charge protection or the charge current reduce to 0.05C, and then rest for 1h.


NOItemsCriterionCondition
3.1Normal Capacity100AhAfter Normal charge, discharge @0.33C current to the end of discharge voltage.
3.2Internal Impedance≤80mΩ@50% SOC @1kHz AC internal resistance test instrument.
3.3Short circuit protectionAuto cutoff load when short circuitConnect the positive and negative of this battery pack through a lead with 0.1Ω resistance.
3.4Cycle life @DOD100%≥2000 cyclesAfter Normal charge,discharge @0.33C current to the end of discharge voltage. Repeat above process until discharge capacity reduce to 80% of initial value.
