As the number of battery cycles increases, the rate of battery capacity decay is inconsistent, leading to a serious imbalance in battery voltage. The “battery barrel effect” will influence the service life of your battery. That’s why you need a active balancer for your battery packs.
Different from inductive balancer, capacitive balancer can achieve the whole group balance. It doesn’t need voltage difference between adjacent batteries to start balancing. After the device is activated, each battery voltage will reduce the capacity decay caused by the battery barrel effect and prolong the duration of the problem.
