Sug, any off road vehicle will benefit from 2 batteries in parallel. You still get 12 volts, but you now have twice the muscle of a single battery. (assuming that the batteries are identical) When you start to add stereos, lighting, winches etc, you can easily drain your stock battery down to the danger level of a no-restart condition. Now you are in trouble because there is no pull starter to rely on. If you don't have a buddy and jumper cables, you are walking.
A second battery is great, but it really needs an isolator to keep one of them from being discharged by your add ons. That battery will always be getting recharged as needed by the alternator, but it is isolated from being discharged down to a level too low to restart.

 

Two batteries, one to run all the stock equipment (that won't discharge when the RZR isn't running), the other to run all your auxilliary electronics (stereo, etc.) when the RZR is off. With an isolator, you prevent a dead starter battery.

 

Exactly how i did mine. Not a single problem running it this way!

 

what size battery is everyone running for their second battery. i've got a single battery right now and was thinking about adding another. i have a radio with 2 speaker set up 2 extra lights and a winch.

 

Dual Odyssey's. One PC925 and one PC925L. Works great.

 

I run twin odyssey 925 batterys

 

X2 Works great!!

 

Why do these machine have such a small charging setup?

 

What Isolators are yall running. I had the sure power on my old rhino and never had a problem with it. Any other brands that are good. Getting ready to do the dual batteries on my rzr.

 

Planning on the PowerStream PST-SSB2180 solid state Smart Battery Isolator but it is not waterproof. I am going to talk to them about a water proof version.
