20kwh Energy storage battery lithium ion high voltage module 400V 50Ah for CATV system
1. Transportation of 20kwh lithium ion battery

  • Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
  • Battery should stay 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 needs to be charged every 6 months if out of use
  • Keep the battery against dropping, turning over and serious stacking during loading.
  • Ensure the single 48V 50Ah battery module in the independent package and keep it face up.

2. Long time storage of 400V 50Ah CATV System battery
If stored for a long time(no used,exceed three months), the cell should be stored in drying and cooling place. The cell’s storage voltage should be around 400V and the cell is to be stored in a condition that the temperature of 23±2℃ and the humidity 0f 45%- 75%. Long-term use of unused
batteries to recharge every 3 months. Ensure that the battery voltage is within the above range.

4. Other Chemical Reaction of lithium ion battery

Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges, the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the discharge time is much shorter than the normal after fully charged, even battery is charged correctly, and this may indicate it is time to change the battery.
