| Typical voltage | 3.2V | ||
| Weight | 288g±12g | ||
| Impendence | ≤3mΩ | Less Than 3mΩ | |
| Charge current (CC-CV) |
Suggestion continue charge current | ≤1C(10A) | 0℃～45℃，Suggest the max charge current less than 1C. To Achieve the max. Service life. 0.2C（CC）to 3.65V, At 3.65V（CV）until the current ≤0.02C, then stop charge. (P.S: Large continue charge rate will reduction of the service life of the cell. Considering the high rate will lead to temperature rising, we are not suggest the battery pack work on high charge rate continue long time.) |
| Max charge current | ≤5C(50A) | ||
| Cut off voltage | 3.65V | ||
| Discharge | Max. continue discharge current |
≤20C(200A) | -20℃~60℃ suggest the max. charge current less than 1C. To Achieve the max. Service life. 0.2C（CC）to 2.0V, stop discharge. (P.S: Large continue discharge rate will reduction of the service life of the cell. Considering the high rate will lead to temperature rising, we are not suggest the battery pack work on high discharge rate continue long time.) |
| Max discharge current(short time) |
≤30C(300A) | ||
| Cut off voltage | 2.0V | ||
