6. Battery operation instruction

Charge and discharge

  • 1 Charging current:Do not surpass the largest charging current that specification stipulated.
  • 2 Charging voltage:Do not surpass the highest limited voltage that specification stipulated.
  • 3 Charging temperature:within temperature scope that specification stipulated.
  • 4 Charge with constant current, then with the constant voltage, no reverse charge, which is dangerous.
  • 5 Special note:

Short time doesn't affect the use of the battery overcharge too, but for a long period of time over discharge or over charge can affect the function of the battery failure, or the battery can't use permanent, appear serious safety hazards, need long time floating please use the recommended floating model specification. Battery when not in use for a long time, because of its own self-discharge characteristics can also cause discharge, to prevent the occurrence of a discharge, battery should maintain a certain capacity, maintain the voltage at 50% state of SOC.

 

7. 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 15℃~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.
