I have a 700-2 That I added a second battery system on. but I'm running a lot of lights and a front and rear winch's. According to the guy at my dealership there is no problem running a 50" light bar on the main battery!
I added the battery under the drivers seat had to build my own box for it I was only able to add a large garden tractor size battery and had to relocate the oil fill tube. start to finish it was about a 6 hour project but I'm a little OCD.
nice I like your set set up I made mine to drop in thru the outside hole with top of the battery flush. I do dig That missive deep cycle battery!I added full size under drivers seat

In all reality is a secondary battery really necessary? I have fog lights, street legal kit, sound bar, and have never had an issue. That being said I don’t leave all that running with my engine off. I just added a winch and only plan to use it if I get stuck, and will only use it with the engine running. So as long as your engine is running and charging the battery that should be sufficient correct?
