Protect your 4WD battery from excessive discharge and let your auxiliary battery supply non-essential loads with a battery isolator.

Going for a camping trip in your RV?  Doing some boating?  Or do you own a truck or commercial vehicle? A battery isolator makes life easier on the road. No more nasty surprises when you try to start your vehicle only to find that it won’t start. We stock a variety of battery products that tick the boxes of high quality, easy to install and compact.  

How A Battery Isolator Works

Most vehicles only include one starter battery. But you might want to add a second battery for work lights, a power winch, camping gear, or simply because you want a backup on long trips.

A battery isolator allows DC power to flow through the isolator, while making electricity flow in one direction. So, when one battery is drained, it won’t pull current from the other battery and leave you with two drained batteries.  

Check out the smart battery isolators offered by Redarc, Enerdrive and CTEK for high quality, innovative products.
