3. Electrical Characteristics & Test Condition
Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%.
NO | Items | Criterion | Condition | |
1 | Internal Impedance | ≤20mΩ | Test the internal resistance of 50% SOC battery pack with 1 kHz AC internal resistance test instrument. | |
2 | Capacity | ≥100Ah | 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 180 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity. | |

5.Storage & 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.
