  • Does Lifepo4 battery wall need consistency
    Nov 09 , 2022
    Does the lifepo4 battery wall need consistency? The answer is yes. The consistency of individual SOC largely determines the discharge capacity of the battery pack. Balanced charging makes it possible to achieve similar initial SOC platforms for individual discharge, which can improve discharge capacity and discharge efficiency (discharge capacity/group capacity). The equalizing mode during chargin...
