2. LiFePO4 Battery Cells 3.2V 100Ah Safety Test

No.	Item	Test method	Criteria
2.1	High Temperature Discharge Performance	The cell was charged in accordance with 4.2,and stored in an ambient temperature of 55±2℃ for 5h,then discharged to 2.0V with 1C constant current.After that,then place the cell in the ambient temperature of 25±2℃ for 4h then check its appearance.	1,Retention capacity at 55℃≥95% 2,No deformation, No crack.
2.2	Low Temperature Discharge Performance	The cell was charged in accordance with 4.2,and stored in an ambient temperature of -20±2℃ for 24h,then discharged to 1.8V with 1C constant current.After that, place it in the ambient temperature of 25±2℃ for 4h, then check its appearance.	1,Retention capacity at -20℃≥70% 2,No deformation, No crack.
2.3	Rate Charge Performance in Normal Temperature	Under the ambient temperature of 25±2℃ a.Discharged to 2.0V with 1C constant current,stay for 1h. b.Charged to 3.65V with 2C constant current,stay for 1h. c.Discharged to 2.0V with 1C constant current.	Capacity retention≥80%
2.4	Rate Discharge Performance in Normal Temperature	The cell was charged in accordance with 4.2,then discharge to 2.0V with 3C current in an ambient temperature of 25±2℃.	Capacity retention≥90%
2.5	Charge Retention	The cell was charged in accordance with 4.2,and stored in an ambient temperature of 25±2℃ for 28 days,and then discharged to 2.0V with 1C constant current.	Capacity retention ≥85% Capacity recovery ≥90%
2.6	Cycle Life (25±2℃)	The cell was charged to 3.65V with 1C CC/CV cut off 0.05C,stayed for 30min;Subsequently,the cell was discharged to 2.0V with constant current 1C,and stayed for 30min;Prior to next charge-discharge cycle.Record all the cycles until the retention capacity＜80%.	≥2000cycles

5. Stotage & Transportation

Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
Battery should be stayed in the ware house -20℃～35℃ where it’s dry, clean, shade, and well-ventilated.
The battery should be stored in 50% SOC during transportation.
The battery need to be charged every 6 months if out of use.
Keep the battery against dropping, turning over and serious stacking during loading.
