RB-BI-120A Bussman Battery Isolator
Designed by Sure Power™, battery isolators are solid state devices in a multi-battery charging system that help ensure engine starting power. The battery isolators act as a check valve to prevent auxiliary batteries from draining the main battery. When installed, isolators allow vehicle accessories to draw current from the auxiliary battery without affecting the battery used for engine starting. This frees up the vehicle’s charging system so that the main and auxiliary batteries can charge and discharge according the needs of their electrical loads.
