Victron Battery Balancer

Victron Battery Balancer Intro

Victron 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

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

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.

How to Connect 48V Batteries by Victron Battery Balancer

A 48V battery bank can be balanced with three Victron Battery Balancers.

Features of Victron Energy Battery Balancer

LED indicators

Green: on (battery voltage > 27,3V) Orange: lower battery leg active (deviation > 0,1V) Orange: upper battery leg active (deviation > 0,1V) Red: alarm (deviation > 0,2V). Remains on until the deviation has reduced to less than 0,14V, or until system, voltage drops to less than 26,6V.

Alarm relay

Normally open. The alarm relay closes when the red LED switches on and opens when the red LED switches off

Alarm reset

Two terminals are available to connect a push button. Interconnecting the two terminals resets the relay. The reset condition will remain active until the alarm is over. Thereafter the relay will close again when a new alarm occurs

Even more insight and control with the midpoint monitoring function of the BMV-702 Battery Monitor

The BMV-702 measures the midpoint of a string of cells or batteries. It displays the deviation from the ideal midpoint in volts or percent. Separate deviation percentages can be set to trigger a visual/audible alarm and to close a potential free relay contact for remote alarm purposes.
