Victron Battery Balancer
The Battery Balancer is designed to equalise the state of charge between two 12V batteries connected in series, or across multiple parallel strings of series-connected batteries. When the system’s charge voltage rises above 27V in a 24V setup, the balancer activates, measuring the voltage of each battery. It then draws up to 1A from the battery (or parallel group) with the higher voltage, helping to distribute the charge evenly and ensure all batteries reach the same state of charge.
