How Do You Balance Lead-acid Batteries?
The Buckets Effect: The amount of water a bucket can hold depends on its shortest stave. In the realm of batteries, the Buckets Effect is observed: The performance of a battery pack depends on the cell with the lowest voltage. When the voltage balancing is poor, the phenomenon occurs that the batter
