3. Electrical Characteristics & Test Condition
@Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%.
| NO | Items | Criterion | Condition | |
| 1 | Internal Impedance | ≤50mΩ | Test the internal resistance of 50% SOC battery pack with 1 kHz AC internal resistance test instrument. | |
| 2 | Capacity | ≥20Ah | 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 | 20A | Charging with this current for more than 0.5h and the added temperature of battery pack less than 20℃. | |
| 5 | MAX discharge Current | 30A | Discharging with this current for more than 0.5h and the added temperature of battery pack less than 35℃. | |
| 6 | Cycle life (DOD%100) | ≥2000cycle | Discharge with the current of 0.5C 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. | |
| 7 | Discharge Temperature Characteristics | -20℃ | ≥70% | At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage. Record the ratio between discharging & charging capacity. |
| 0℃ | ≥80% | |||
| 25℃ | 100% | |||
| 55℃ | ≥95% | |||
| 8 | Charge Retention ability | remain capacity≥90% | Charge the battery to full capacity and store it for 28days, and then discharge it with 0.33C to the cut-off voltage. | |
4. 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 warehouse -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.
