There is adjacent voltage difference of batteries when charging and discharging, which triggers the equalization of this inductive balancer. When the adjacent battery voltage difference reaches 0.1V or more, the internal trigger equalization work is performed. It will keep working until the adjacent battery voltage difference stops within 0.03V.
The battery pack voltage error will also be pulled back to the desired value. It’s effective to reduce battery maintenance costs. It can significantly balance battery voltage, and improve the overall efficiency of the battery pack.
