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 | ≥800mAh | 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. |
| 3 | Short circuit protection | Automatically cutoff discharging when short circuit, and release after remove the lead. | Connect the positive and negative of this battery pack through a lead with the resistance less than 5mΩ. |
| 4 | MAX charge Current | 400mAh | Charging with this current for more than 0.5h and the added temperature of battery pack less than 20℃. |

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.
6. Warning & Tips
Before using the battery, please read and observe the specifications and precautions on the battery surface. Improper use may cause the battery to heat up, catch fire, crack, damage or decrease its capacity.
