2. Product Performance


NO. Items Criteria Testing method
2.1 Rated Capacity 14Ah Rest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the discharge cutoff voltage. Repeat above process for three times, if the discharge time is not less than 120 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity.
2.2 Rated Energy


2.3 Internal resistance


50% battery SOC state frequency of 1 KHZ ac resistance tester

Cycle life


≥2000cycle Discharge with the current of 0.33C until it can’t discharge, and then rest it for 1h. Charge the battery following CC(0.33C)/CV(14.6V) mode to full capacity, and then rest it for 1h. Repeat above process until full charged capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.

Discharge Temperature


-20℃ ≥70% At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage and record charge capacity. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage.
-0℃ ≥80%
25℃ ≥100%
55℃ ≥95%
2.7 Charge Retention ability



Charge the battery to full capacity and store it for 28days, and then discharge it with 0.33C to the cut-off voltage.
Recovery capacity≥90%

Recommended storage environment:


Long time storage:

If the battery need be stored for a long time, the voltage should be 52.8V(50%SOC), and stored in the condition as storage proposal. It need at least one charge & discharge cycle every six months



5. Transportation


1) Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.

2) Battery should be stayed in the warehouse 15℃~35℃ where it’s dry, clean, shade, and well-ventilated.

3) The battery should be stored in 50% SOC during transportation.

4) The battery need to be charged every 6 months if out of use

5)  Keep the battery against dropping, turning over and serious stacking during loading.
