The battery balancer balances the state of charge of two 12V batteries in series or several battery strings in series in parallel.When the charging voltage of the 24V battery system increases to more than 27V, the battery balancer will turn on and compare the voltages of the two batteries in series.The battery balancer will draw up to 1A from the battery with the highest voltage (or batteries in parallel).The resulting difference in charging current will ensure that all batteries converge to the same state of charge.
