Victron Energy Battery Balancer

The Victron Energy Battery Balancer helps equalize the state of charge of two series-connected 12V batteries or multiple parallel strings of series-connected batteries. By monitoring the voltage of each battery in a 24V system, it compensates for voltage differences during charging. Multiple balancers can be connected for larger battery banks, including 48V systems.

FEATURES

• Automatic balancing: Transfers current from the higher-voltage battery to help equalize the state of charge.

• 24V battery systems: Activates when the system charging voltage rises above approximately 27.3V.

• 48V compatibility: Three balancers can be used to balance a 48V battery bank.

• Voltage deviation alarm: Built-in relay signals excessive voltage imbalance.

• Thermal protection: Includes protection against excessive temperature.

• Expandable system: Multiple balancers can be connected in parallel when required.

INSTALLATION

Mount vertically on a well-ventilated surface near the batteries, but never directly above them because of potentially corrosive battery gases. Follow the manufacturer’s wiring instructions and applicable electrical protection requirements.

IMPORTANT: This product balances compatible battery banks; it does not charge batteries. Confirm battery configuration and system voltage before installation.
