| 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 |
|

| 11 |
Cell configuration requirements 15%SOC |
Capacity:1% Impedance:0.2mΩ voltage:5mv |
|
| 12 | Rated Capacity | ||
| 13 | Cycle Life | ≥1000 |
Test condition: Charge:0.5C CC to 3.65V, CV to 0.02C. Discharge:0.5C DC to 2.5V 80% or more of 1st cycle capacity at 0.5c discharge of Operation |
| 14 | Self-discharge |
<4% monthly
|
After the standard charging, storied the cells under the condition as No.4.4 for 28 days, then measured the capacity with 0.5C till 2.5V |
