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 | ≥3000mAh | 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 | 800mAh | Charging with this current for more than 0.5h and the added
temperature of battery pack less than 20℃. |
| 5 | MAX discharge Current | 3000mAh/3s | Discharging with this current for more than 0.5h and the added
temperature of battery pack less than 35℃. |
| 6 |
Cycle life (DOD%100) | ≥800cycle | 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. |

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. Shenzhen Guanyu New Energy Technology Co.,
Ltd. is not responsible for any accidents caused by non-compliance
