9.7. The Battery Balancer
A consideration can be made to add a Battery Balancer to the system. A Battery Balancer will equalize 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 27.3V, 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 0.7A 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, one between each battery.
