4. Stotage & 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.

5. LiFePO4 battery cells advantage

Output with high efficiency: Standard discharge current is 0.3C-1C, pulse discharge current is 3.5C for 3 seconds.
Good performance under wide temperature -20-60℃. The battery structure is safe and good.
Good safety performance: When the pressure inside the battery is too large, the one-way safety valve will release gas and heat to make sure battery perform well. When the internal pressure reaches a certain level, the valve will be open immediately which can protect the battery from burning and explosion.
Long cycle life time, the discharge capacity is still over 80% after 2000 cycle times of single cell(100%DOD).
It can fast charging. It could be charged to 80% within 20 minutes and charged full with 2-3h.
Low self-discharge. Less than 3% per month.
No pollution during manufacture and usage.
