  • Why Proper Cell Balancing is Necessary in Battery Packs

    This is not only for the performance of the battery pack, but also for optimal life cycles. The use of cell balancing enables us to design a battery with larger capacity for an application because balancing allows the battery to achieve a higher state of charge (SOC). A lot of companies choose not to use cell balancing at the start of their ...
