P500 2nd Battery Size

[States]

What size battery are you running for your accessory battery? Plan on adding light bar, rear lights, winch, windshield wiper and interior light. Have read that some are using lawn mower batteries, would these handle the load and if so what size should I be looking at.
Also what type of battery support are you using for the under drivers seat location?

I am running about the same with a garden tractor battery with no issue at all. That size battery fits nice under the drivers seat. Enjoy

P500 - Battery Under Seat?

Has anyone ever installed their second battery under the driver's seat on a 500? Can't believe I would be the first to want to do this! I've searched the old threads and the web and can't find where anyone has done it, it's always placed up front under the hood. Just makes sense for me...

Has anyone used the TRUE UTV-SBI-CM UTV DUAL BATTERY AND MONITOR KIT? Instructions do not show how to power accessories from second battery. I’m assuming that I just run a wire from the isolator to a new fuse box??

I ran majority of my stuff from hot post (on auxiliary battery) through a waterproof resettable breaker then into fuse block for each powered item. I used the Blue Sea mini add a battery kit, has work flawlessly since 2015. I use an AGM Odyssey Extreme PC925, it fits inside a 50 cal steel ammo can and so far has worked very well. Think it’s 330 CCA don’t remember the reserve info, as I recall it was a bit spendy here in Canada. As noted in other threads, if I did it again I’d install the auxiliary battery under the driver’s seat. Leaves more room under hood plus you can install a huge battery if desired under the seat.
Cheers,

States, don’t mind my crayon drawing, but this is what I planned.... use the True isolator and a stinger. I didn’t add the stinger yet. The True is connected to both batteries. And I run a fuse box off the accessories battery. The True ensures the chassis battery is charged before charging the accessory battery.

Thanks for the sketch. Pretty close to what I figured out

I’ve got all the pieces in place and hooked up except the main battery cable to the isolator. Can anybody give me ideas on how they got this new no.1 wire into the existing battery box. Isolator is under the hood

What is the specific issue? you open the battery box and run the cable. positive from that battery to the True. The battery box provides an opening (bottom right) of the box when looking at it, to run the additional cable out of. Also, I’d have to look but I am pretty sure I ran smaller gage cable. Maybe 4-6, I think.

I cannot find an opening in the existing box. I checked all around it. It’s a 2018

The chassis cables are finding there way into the battery box somehow. I don’t have a 2018. Maybe the design of the battery box changed. Maybe post a pic and someone can offer help
