Quick Power 200 Amp Battery Isolator - Bi303306

Battery Isolator switch for up to 200 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.
