Victron Energy Battery Balancer 300.00332
The Battery Balancer balances the charging status of the two series connected to 12V batteries or to several parallel series of connected batteries.
When the voltage of the 24 V battery system exceeds 27 V, the Battery Balancer will operate and compare the voltages of the two battery series connected to the battery. The Battery Balancer will draw current up to 1 A from the battery (or parallel connected batteries) at a higher voltage. The difference in charging current that will be generated will ensure that all batteries will be charged in the same charging mode.
If needed, many Battery Balancers to be connected in parallel. The A 48 V battery can be balanced with three battery balancers.
