Product details

Batteries connected in series of a 24 V battery bank can have different charge states, which can lead to an increasing imbalance during operation and when using 24 V charging technology. This can result in premature failure of the battery bank. A battery balancer can remedy this. The balancer becomes active at a voltage of 27.3 V and above and balances the state of charge of the two 12 V batteries connected in series with a current of max. 0.7 A. In doing so, up to 1 A is taken from the battery with the highest voltage. In addition, LED status indicators help to keep an up-to-date overview at all times and an integrated alarm sounds if the deviation is greater than 0.2 A.
For large capacity battery banks, several balancers can be connected in parallel. Two balancers are required for a 36 V battery bank and three for a 48 V bank.

Connection example with 2 batteries
This Victron Battery Balancer is connected to two 12V batteries (24V system) connected in series.

Connection example with 4 batteries
Three battery balancers connected to four 12V batteries in series (48V system).

  • What is the maximum battery capacity (Ah) that can be connected to a battery balancer?
What matters is not the battery capacity, but the number of strings. (A string is 2 or more batteries connected in series.)
A balancer can equalise about 5-10 strings of new batteries, but the more strings connected, the longer the battery equalisation will take.
For heavy battery use, one balancer should be used per 5 strings.
  • Can I also connect this balancer to lithium batteries (LiFePO4)?
No, the balancer is intended for use with lead-acid battery types only.
Lithium batteries usually have a battery management system (BMS) with an integrated balancer. Therefore, no additional balancer is needed.
