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
The WRND dual battery charger uses the starting or primary battery of the vehicle to charge the secondary utility battery via its internal DC to DC converter when the engine is running.
The NLDC-25 from National Luna is a DC to DC battery charger and isolator for a dual-battery system.
It will charge an auxiliary or service battery from a vehicle alternator or Solar panel up to 25A output current.
Traditional 12V and 24V vehicle alternators as well as variable voltage alternators are supported.
