Victron Energy Battery Balancer eliminates the effect of load imbalance and improves the life of your battery bank Victron Energy Battery Balancer equalizes the state of charge of two series connected 12-Volt batteries, or of several parallel strings of series connected batteries When the charge voltage of a 24-Volt battery system increases to more than 27-Volt, Victron Energy Battery Balancer will turn on and compare the voltage over the two series connected batteries Victron Energy Battery Balancer will draw a current of up to 1Amp 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 If needed, several balancers can be paralleled. A 48V battery bank can be balanced with three Victron Energy Battery Balancers
