How to take care of LiFePO4 Lithium Battery?
1. Charging: 12V 50Ah battery can be charged with 50A current at maximum. However, we will recommend to charge the battery at 10A (0.2C), which will maximize the battery's life span and cycles.
2. Storage: Keep your battery in a cool and dry place (preferably between 0 and 45°). Operating temperature: Charge at 0℃-45℃;Discharge at -20℃-60℃.
3. Cleaning: Never use a steam pressure washer when cleaning the battery .Never completely immerse the battery in water. Wiping it off with a damp cloth.
