The Victron Energy Battery Balancer (BBA000100100) from Nomadic Supply Company® The Battery Balancer equalizes the state of charge across series-connected 12V batteries or parallel strings of series-connected batteries.
The Battery Balancer equalizes the state of charge of two series connected 12V batteries, or of several parallel strings of series connected batteries. When the charge voltage of a 24V battery system increases to more than 27V, the Battery Balancer will turn on and compare the voltage over the two series connected batteries. The Battery Balancer will draw a current of up to 1A 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 Battery Balancers.
Victron Energy Battery Balancer (BBA000100100) Features:
- Battery Bank Equalization. Automatically equalizes the state of charge between two series-connected 12V batteries in a 24V battery bank.
- Active Balancing. Transfers energy from the higher-voltage battery to the lower-voltage battery to maintain equal charge levels.
- LED Status Indication. Built-in LEDs show balancing status and alert to battery imbalance conditions requiring attention.
- Alarm Output. Configurable alarm relay output warns when the voltage difference between batteries exceeds acceptable thresholds.
- Low Power Consumption. Efficient operation minimizes parasitic draw from the battery bank during standby and active balancing.
