A compact, automatic, parallel split-charge isolator for 4x4 motor vehicles by National Luna, featuring intelligent control electronics and a low-loss, high-current solenoid.
The solenoid monitors the voltage on the main/starter battery. When the engine is started, the Intelligent Solenoid directs the alertnator's output to the main battery only, so it is charged for 5 minutes before the auxiliary battery is connected and charged as well.
Installing the dual battery system is simple and straight forward. See the user manual for reference.
