The longevity of an expensive battery bank can be reduced considerably by different states of charge of the separate batteries. The Victron Energy Battery Balancer balances the states of charge of batteries in series.
If the state of charge of a 24V battery system exceeds 27V, the Battery Balancer is activated in order to compare the voltage of the two batteries in series. The Battery Balancer will draw a current of up to 1A from the battery (or batteries connected in parallel) with the highest voltage. The resulting charge current differential ensures that all batteries adopt the same state of charge.
If necessary, several Battery Balancers can be connected in parallel. A 48V battery bank can be balanced with three Battery Balancers, for example.
