If user needs more groups for parallel connection, please reconfirm details with us.

3.Electrical Characteristics & Test Condition

Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%.


Normal charge:Charge battery under CC(0.33C)/CV(43.8V) mode until over charge protection or the charge current reduce to 0.05C, and then rest for 1h.







Normal Capacity


After Normal charge, discharge @0.33C current to the end of discharge voltage.


Internal Impedance


@50% SOC @1kHz AC internal resistance test instrument.


Short circuit protection

Auto cutoff load when short circuit

Connect the positive and negative of this battery pack through a lead with 0.1Ω resistance.


Cycle life @DOD100%

≥2000 cycles

After Normal charge,discharge @0.33C current to the end of discharge voltage. Repeat above process until discharge capacity reduce to 80% of initial value.


Discharge temperature


-20℃(6h) ≥70%



Ratio of Capacity @specified temperature

/Capacity @ 25℃ accord with Criterion


0℃(6h) ≥80%
25℃(4h) ≥100%
55℃(4h) ≥95%

Capacity retention rate

remain capacity


After normal charge, store the battery @25±5℃ for 28days, then discharge capacity @0.33C,the retention capacity accord with criterion.
