Battery Isolator Kits

Our XD & HD battery isolators for dual battery set-ups handle alternators up to 140 and 200 amps. For 12-36V DC negative ground electrical systems. Battery isolators allow you to charge either one or both batteries as required. Designed to allow flow through charging of two 12 volt battery banks from your vehicle's alternator. Power will flow from your alternator through the isolator then to each battery to keep them fully charged.

By controlling the one way flow of power to each battery bank, your accessories such as a winch will draw power only from the designated battery and not drain down your main vehicle battery. Battery isolators prevent a battery with a higher charge from draining into a battery with a lower charge. Ensures your accessories won't drain your starting battery.
