Best Lithium Batteries for Electric UTVs & Side-by-Sides

We are beyond impressed with the performance of these batteries. They're noticeably more powerful than pretty much any other brand we've used in our shop. And honestly the best part about them is that we don't have any warranty issues, after I installs are done our customers enjoy the units and we don't have to service them several times to get it right like we do with other brands. We are very happy at our dealership with Fleet Lithium batteries. We've installed hundreds of them, I'm not sure why they're not more reviews on these batteries but I can only assume because not many people come back to this website to review them. We're at lakesidebuggies.com and we've installed more of these than I can possibly even count. Nothing but praises for this company.

I've got a 2013 Ranger we picked the 51160 ( standard range ) and it's like a brand new machine. Easily double the range much more torque, amd it gets up hills effortlessly. I highly recommend Fleet lithium. We are very impressed

We love our new battery, we are consistently seeing over 50 miles and range, no more mess and no more acid to deal with, and the cart has so much more pickup and speed now. Well worth the money, premium quality, top notch service! Thank you for making a great product!

Swapped into my Badboy buggy in under an hour. The cheap packs I tried before would cut out during heavy use; this Fleet Lithium pack never throttles. I get about 40-44 miles on flat courses.

I installed this pack in my Textron Prowler EV two months ago what a difference! Other cheap lithium packs would randomly shut down mid-ride, but this one delivers consistent power. I'm regularly seeing 42 miles per charge, though it varies with terrain and load.

Fleet is what they said it was: reliable, strong, and no drama.

I swapped out a RoyPow and couldn’t believe the torque boost. Fleet is on another level.

Instant power, zero maintenance. Way better than anything I’ve used before.”

Absolutely the best built Lithium Battery on the market.
The Huge BMS handles the most extreme terrain, without compromise.

I own a Badboy buggy and cheap lithium packs always failed within months. This bundle's decade-long warranty, plus the protective cell gap, ensure it won't quit on me. I average about 41-46 miles depending on conditions.

My Textron Prowler EV had issues with past packs shutting down. Fleet Lithium support helped me update firmware via the app, and now I hit around 42-45 miles consistently.

I was nervous after cheap packs shut down unexpectedly. Installing this in my Textron Prowler EV, the built-in fire suppressor and NextGen BMS gave peace of mind. Saw over 43 miles in mixed driving.

In my Badboy buggy, heavy hills used to kill my cheap pack. With this bundle I maintain steady power and get 40+ miles before needing a recharge.

Installed in my Badboy buggy, I've gotten a solid 44 miles on a single charge cheap packs I tried would die at 25-30. Smooth operation and zero shutdowns even under load.

Living in Wisconsin, I needed reliable heat. Other cheap packs shut off when temps dipped, but the built-in heating elements on this bundle keep my Badboy buggy running smoothly. I've been hitting around 45 miles per charge, depending on usage.
