Discharge Temperature

Characteristics

 -20℃ ≥70% At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage and record charge capacity. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage.
0℃ ≥80%
25℃ 100%
55℃ ≥95%
8

Charge Retention ability

remain capacity≥90%

 Charge the battery to full capacity and store it for 28days, and then discharge it with 0.33C to the cut-off voltage.

4. Circuit Protection

The batteries are supplied with a LiFePO4 Battery Management System (BMS)that can monitor and optimized each single prismatic cell during charge & discharge, to protect the battery pack overcharge, over discharge, over current, over heat, etc. It would cut off the battery input or output for protection once necessary. Overall, the BMS helps to ensure safe and accurate running.
