Battery Balancer    (Will not work on 36V Bank)The 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. 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.WARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
