Forget the other separate switches and battery isolators. The battery Doctor does it all and you don't have to touch it!

I wanted to add a second deep cycle battery to my boat, just to run the stereo and accessories. In my previous boat I had a manual switch, which was a hassle, as you had to remember to switch it whenever you wanted to isolate your starter battery. Well no more. The Battery Dr does it all for you automaticay so you will never drain your starter battery, so you'll always be able to get home!

I have had numerous other batter isolators that were a lot more expensive but none of them was this easy to install and use. I use it on my SXS.

I installed this in my 2010 Silverado and no problems so far two weeks later. Make sure you have the 145 amp alternator in you truck. It took 2 hours to install start to finish.
