This Battery Balancer is used to balance large string of batteries in series. It cand be used my 12V, 24V or 48V PowerBrick product range.

This accessory is useful for a permanent installation of batteries in series to ensure that the batteries are always balanced with each other.

  • This device 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.
