No | items | specifications | Note |
1 | Charge cut-off voltage | 3.65V |
The capacity means the discharge capacity of the cell, which is measured with discharge current of 0.5C with 2.5V cut-off voltage after standard charge |
2 | Nominal voltage | 3.2V | |
3 | Discharge cut-off voltage | 2.0V | |
4 | Rated Capacity | 50Ah @0.5C Discharge | |
5 | Standard Charging method |
0.5C CC(constant current)charge to 3.65V,then CV(constant voltage 3.65V)charge till charge current decline to ≤0.05C |
|
6 | Max charge current | 1.0C | |
7 | discharge current |
1.0C(Continuous discharge current ) 2.0C (Instantaneous discharge current -10-60℃) |
|
8 | Operating temperature |
Discharging:-10℃~60℃ High/low temperature environment reduce battery charge efficiency and influence battery life |
