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
| Capacity | Energy (kWh) | Estimated Range | Best For |
|---|---|---|---|
| 51V 105Ah | 5.38 kWh | Up to 50 miles* | Daily driving, errands, golf |
| 51V 168Ah | 8.60 kWh | Up to 75 miles* | All-day use, long routes |
| 51V 210Ah | 10.75 kWh | Up to 90 miles* | Maximum range, commercial & fleet use |
Cold-Weather Charging Protection — Standard on Every Pack
Every Fleet Lithium battery includes a built-in heater that activates automatically when charging below 32°F (0°C). This protects the cells during cold-weather charging — no extra charge, unlike competitors who charge $200–$400 for heated versions.

FAQ
Will this fit my Polaris Ranger EV?
Yes. The included BR3110 bracket kit ensures a secure, factory-fit installation for all Ranger EV models (2010–2024), including the Li-Ion variant. No modifications required.
Do I need to reprogram my controller?
No. Works with your factory 48V controller out of the box — both lead-acid and Li-Ion models.
How long does installation take?
30–60 minutes with basic hand tools.
Does it work in cold weather?
Yes. The built-in heater activates automatically when the battery is plugged in for charging below 32°F, protecting the cells during cold-weather charging. The heater does not run during discharge/driving.
Which capacity should I choose?
105Ah for up to 50 miles (most popular), 168Ah for up to 75 miles, or 210Ah for up to 90 miles.
*Range estimates represent maximum distance under ideal conditions (flat terrain, single occupant, 12–15 mph, fully charged, 70°F). Actual range varies based on terrain, weight, speed, temperature, and driving habits.
