Good day All, starting to plan for hunting season / winter here, looking at putting in a second battery. Any thoughts on the Quad Boss Battery Isolator, or some other isolator that would be just as good/better? Thanks!

I trust Quad Boss but..not only is that expensive, it doesn't allow you to use the second battery for starting if needed...ie no bypass.  This one is much less and does:

Those are both VERY expensive options.  Here is what i have run in the past on my Rhino (3 years of running it and it never failed)

It can be bought on Amazon also.
It also has wiring for connecting the batteries for starting purposes

those other 2 are just ripping you off if you ask me.

Thanks for the feedback (NMK, chuddly) on the battery isolators.

I see princess auto has one on sale next week for $25  .I have used one my jeep with no problem but I don't know how it would be on a sxs .
