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.
