Oddeľovací transformátor Victron Energy BBA000100100 vstupný prúd max. 1 A farba krytu modrá

The Victron Energy BBA000100100 Battery Balancer equalizes the state of charge between two series-connected 12V batteries or between several parallel strings of series-connected batteries. When the charge voltage of a 24V battery system rises above 27V, the balancer activates and compares the voltages of the two series-connected batteries. It draws up to 1 A from the battery (or parallel-connected batteries) with the higher voltage so that the charge current differential causes the batteries to converge to the same state of charge. Multiple balancers can be paralleled when required; a 48V battery bank can be balanced using three units.

Advantages

This device provides automatic passive balancing without the need for user adjustments. It limits the balancing current to a maximum of 1 A, protecting batteries from excessive discharge during the balancing process. The compact blue housing is intended for easy installation in battery systems and allows paralleling of multiple units for higher-voltage banks.

Key specifications

How to use

Install the balancer across the two series-connected 12V battery terminals so it monitors the voltage difference between the batteries. When the system charge voltage exceeds 27V the unit will automatically start drawing current from the higher-voltage battery up to 1 A. For larger battery banks, connect multiple balancers in parallel as required (for example three units for a 48V bank). Follow standard safety procedures: isolate circuits before installation and ensure correct polarity and secure connections.

Recommendations

Use the balancer in systems where series-connected battery mismatch is possible; do not rely on it as a substitute for regular battery maintenance. For longer-term or larger imbalances consider professional battery testing and replacement when necessary.
