2. LiFePO4 Battery Cells 3.2V 27Ah Electrical Characteristics & Test Condition

@Ambient Temperature 25±5℃ & Humidity 45%~75%.

Test item	Test Method	Criteria
1. High Temperature Performance	A cell is charged in accordance with 6.2, and stored in an ambient temperature of 55℃±2℃ for 4 h,then discharged to cut-off voltage at a constant current of 0.5C. After that, fetch out the cell and place it in the ambient temperature of 23℃±2℃ for 4 h, then check its appearance.	1.Capacity retention:≥95%; 2. No distortion, no rupture.
2. Low Temperature Performance	A cell is charged in accordance with 6.2,and stored in an ambient temperature of -20℃±2℃ for 20hours,then discharged to cut-off voltage at a constant current of 0.5C. After that , fetch out the cell and place it in the ambient temperature of 23℃±2℃for 4hours, then check its appearance.	1.Capacity retention:≥60%; 2.Nodistortion,no rupture
3. 1C Normal Discharge Performance	A cell is charged in accordance with 6.2, then discharged to cut-off voltage at a constant current of 1C in an ambient temperature of 23℃±2℃. After that,fetch out the cell and place it in the ambient temperature of 23℃±2℃for 4h, then check its appearance	Capacity retention:≥95%
4. 2C Normal Discharge Performance	A cell is charged in accordance with 6.2, then discharged to cut-off voltage at a constant current of 2C in an ambient temperature of 23℃±2℃. After that,fetch out the cell and place it in the ambient temperature of 23℃±2℃for 4h, then check its appearance	Capacity retention:≥90%
5. Capacity Retention	A cell is charged in accordance with 6.2, and stored in an ambient temperature of 23℃±2℃ for 28d, then discharged to cut-off voltage at a constant current of 0.5C.	Capacity retention:≥80%
6. Cycle Life (23℃±2℃)	A cell is charged to end-of-charge voltage at a current of 0.5C, and then charged at a constant voltage of 3.65V until the charge current is less than 0.05C, after that stored for 20min; Subsequently, the cell is discharged to cut-off voltage at a constant current of 0.5C, and stored 30min; prior to next charge-discharge cycle. The cell shall be continuously charged and discharged for 2000 times.	capacity retention:≥80%
