Fleet Lithium 51 Volt Battery Bundle for Polaris Ranger EV (2010–2024)
Drop-In Lithium Power for Your Polaris Ranger EV
Replace all eight lead-acid batteries in your Polaris Ranger EV with a single, lightweight 48V LiFePO4 lithium battery conversion kit from Fleet Lithium. The factory Ranger EV uses two battery packs of four 12V batteries wired in series (8 batteries total, 48V). Our drop-in kits consolidate all of that into one or two compact units — no programming, no special tools. Choose the capacity that matches your driving needs and enjoy longer range, faster charging, and maintenance-free performance for years to come.
Choose Your Range

Awesome kit. We Live in a very cold climate, our ranger gets a ton of use year round and especially during the winter so the cold weather performance was a must for us. We've had the kit installed for about a year now and it's been perfect. Customer service has been super helpful the one or two times we had questions and we've got a couple of neighbors who run the kits as well and they say the same thing. Kevin and his crew are really top notch!
Hi Randy, thank you so much for sharing your experience! We're thrilled to hear the kit performs well in your cold climate and that our customer service has been helpful. We appreciate your support and the recommendations to your neighbors. Thanks for choosing Fleet Lithium!
Was a slight hick up with the darn computer bot. Once we got thru that the service and help with my change over was top notch.

Hi Ryan, we're thrilled to hear your Ranger EV is performing so well with our battery! Thanks for sharing your experience and for choosing Fleet Lithium. Enjoy the longer range and better power!
Routing and checking the connections on the Polaris Ranger EV bundle took longer than expected, but the parts fit correctly. The improved power delivery and reduced maintenance made the extra effort worthwhile.
Absolutely Incredible Range. We replaced our 4 year old Trojan batteries this spring with the 210 AH dual battery kit and we are blown away! We use the buggy to secure the perimeter of a 300 acre lot in South Carolina. We typically put about 200 miles per week on this unit. We have been testing this kit for about a month now and we are getting every bit of 80 miles per charge. Its absolutely unbelievable. Thank you Fleet Lithium!
After a few months of use I can confidently say this was worth it. No maintenance, great range, and consistent power every time. Huge upgrade from stock.

The battery charges quickly and holds power for a long time. Installed this kit and my golf cart instantly felt more powerful. I love the Bluetooth monitoring features.
I especially like being able to monitor the battery from my phone. Power stays strong on inclines instead of dropping off the way it used to. Moving away from lead-acid produced an immediate and obvious improvement.
I love the Bluetooth monitoring features. No more voltage sag even on steep hills. It's a night and day difference from lead-acid batteries.

Let customers speak for us
The customer service and the battery itself from Fleet Lithium is unbeatable. One of the best experiences as a customer I have ever had. They stand by their product and help you every step of the way to ensure you are happy in your purchase. The install was easy once you know where everything is supposed to go and the battery has performed flawlessly in my Bad Boy Recoil since installation. It made it a lot lighter and the buggy is obviously quicker now and I was able to ride it around the farm for hours in fast mode the other day and only used 25% of the battery carrying a buddy and myself. It is really amazing.
Cannot thank these guys enough. Our Hunting buggy is a whole new animal of its own! The team did a great job answering questions, shipping took 3 days and i was even able to reach the support team at 4pm on a Saturday during install. Cannot thank them enough! Don't think twice, Fleet is the way to go for your lithium job.

Cabels look great. Will be installing them by the end of the week. Frank
The BlueMax 200Ah marine battery has provided steady power for onboard electronics and normal time on the water. It is easier to handle than the older battery and has required very little attention between trips.
