Quick Power 120 Amp Battery Isolator Bi303303

Battery Isolator switch for up to 120 Amp alternators conveniently allows for adding a spare battery to run accessories in your car, boat or RV. This fully automatic switch allows for your engine alternator or aux battery charger to charge 2 batteries, while keeping the batteries electrically isolated from each other. This means that you can run your spare battery down, without worry of running down your starting battery.

This waterproof unit will work in a marine environment, as well as stand up to extreme heat. The Battery Isolator switch will prevent current flow from one battery to another, thus allowing each battery to be an independent power source
