Remark:

1) Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.

2) Battery should be storaged in the warehouse 15℃~35℃ (59℉~95℉), where dry, clean, shade, and well-ventilated circumstance.

3) The battery should be stored in 50% SOC during transportation.

4) The battery need to be charged every 6 months if out of use

5) Keep the battery against dropping, turning over and serious stacking during loading.


3. Product Performance


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 Capacity40AhAfter Normal charge, discharge @0.33C current to the end of discharge voltage.
