the steel stick with 9.1Kg|
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 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.
