The problem: the service life of an expensive battery bank can be substantially shortened due to state of charge unbalance One battery with a slightly higher internal leakage current in a 24V,36V, 48V bank of several series/parallel connected batteries will cause undercharge of that battery and parallel connected batteries, and overcharge of the series connected batteries. Moreover, when new cells or batteries are connected in series, they should all have the same initial state of charge. Small differences will be ironed out during absorption or equalize charging, but large differences will result in damage due to excessive gassing (caused by overcharging) of the batteries with the higher initial state of charge and sulphation (caused by undercharging) of the batteries with the lower initial state of charge. The Solution: battery balancing The 48V bluetooth Battery Balancer equalizes the state of charge of two-four series connected 12V batteries, or of several parallel strings of series connected batteries. The Battery Balancer will draw a current of up to 1.0A from the battery (or parallel connected batteries) with the highest voltage. The resulting charge current differential will ensure that all batteries will converge to the same state of charge.
