WARN 120 Amp Dual Battery Isolator
DUAL BATTERY ISOLATOR Because of the increased demands a winch and other accessories place on the DC power supply, many vehicles have multiple batteries-one to start the engine and another to power accessories. The WARN battery isolator prevents the problem of multi-battery drain. So no matter how drained your accessory battery becomes, it will never drain power from the battery you're depending on to start your engine.
