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.
