Adding a 2nd battery in a PRO XP without buying an overpriced "kit"!

- I've always wanted to add a second battery in Provolone, and my opportunity has finally come. The main battery is dead, so it is time for the upgrade.
I looked at some of the kits available, and they want way too much money for a couple a bracket, a couple bolts, and some wire. Why would I spend $100 on their system that just ties 2 batteries together when I could spend a fraction of that and have battery isolation? I don't know either.
This video shows what I ended up doing instead. Other than the cost of the batteries, I'm only into this project for $45! That's a huge savings.
This machine is my 2020 Polaris RZR PRO XP. The wiring and battery compartment is the same on the 2021 and 2022 models as well.
Thank you so much for watching! I genuinely appreciate every viewer and every subscriber! Check out the playlist for many more videos about the PRO XP!

6 gauge wire - you can get any length, color, variety, and you can even get them pre-made with eyelets on them. This is just one example - www.amazon.com/Gauge-Wire-iGr...
The toggle switch I used - 5-pack - www.amazon.com/Nilight-Rocker... - Auta a dopravní prostředky
I enjoy the detail put into these videos
I try my best! Thanks for watching!
Great video! I've been thinking about doing this as well.
Thanks! I've tested it by leaving lights on for hours, and when I was ready to leave it still read 12.4 on the main battery. Should have done it sooner!
Thanks for the video, just subscribed. I have a 2020 Pro XP 4. Just found out that I fried the power steering ($2,000+ mistake) because I was having to jump the battery so often. It was my fault for not realizing this. I know now though. I'll be adding a second battery for sure. With the Rugged Radio and Warn Winch installs they had me going directly to the battery. I'd assume then the 40amp fuse would be fine for the other accessories. What amp fuse was originally protecting the bus bar up front? If it was larger than 40amp why did you initially decide to with with 40? Thanks again for the video.
Thanks for watching and for the sub! I picked 40 amp because the main fuse on the pulse bar is 40 amps. However, I found later that the factory winch connections are made at the pulse bar input connections BEFORE the pulse bar integrated 40 amp fuse, so I blew my 40 amp fuse when using the winch for the first time. I had to reconfigure the wiring a little bit so the winch doesn't go through my fuse anymore. But yes, the radio you want direct to the battery to get the cleanest power possible, and the winch just because it takes so much amperage. Outside of that, batteries are working great, and I've left my lights on for hours with no problems starting it later!
Hello, copied this, works great, thanks, 2 questions, the accessorie switches still work with key off, and also do you leave the toggle switch in the on or off position at all times? Thanks
You'll want to be sure the accessory switches are fed from the switched feed on your pulse bar, or it will drain you battery down. I leave the switch in the "off" position, unless the primary battery goes dead and it won't start, in which case I can throw the switch to "on" which ties the batteries together to give me more power. Once it's running, I put the switch back to "off". With it on, both batteries will drain down slowly over time because it's powering the isolator relay. Hope that helps! Thanks for watching!
how did you get those Interstate batteries to fit ? they say they"re over 6 1/2 inches tall ? My 21 pro xp only has 5 1/2 height clearance . I have to order one ,none in stock to measure, but going by mgt specs.
The ones I have listed here are a direct replacement for the OEM battery. Same size and everything! Technically, the OEM battery is sitting on its side, so the height actually becomes the width. Perhaps that's where the sizes aren't adding up? In any case, they fit perfectly down in there, and I haven't been left stranded once since I added that second battery. Definitely worth it in my opinion! Thanks for watching!
Do you run your winch off the main battery or secondary?
Hi there. The factory winch attaches to the pulse bar, directly to the 6 gauge wires that feed the bar. In the video, you'll see that I diverted that wire under the armrest so it goes to the secondary battery. If I had an aftermarket winch that went straight to the battery, I would attach it to the secondary. However, unless you're using the winch for plowing with frequent in/out movement, it really shouldn't matter which one you go to. Hope that helps! Thanks for watching!
Do you flip the switch to charge the accessory battery?
No, the isolator automatically connects the two batteries together when it senses voltage above around 13v so you don't have to worry about it. I've only used the switch once after the machine had been sitting a while and the primary battery was too low to crank it. Beats jump starting it!
Was that a 40 amp block?
Yes it was. However, I have found that 40 amps is not enough if you have a winch. Under full load, a 40 amp fuse will blow. It's enough for everything else, but not the winch. I ended up replacing it with a straight junction block instead for now, and will likely run a dedicated line for the winch.
