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 (2010–2021), including the Li-Ion variant. No modifications required.

I have the Li-Ion model — do I still need this kit?

Yes! The factory Li-Ion pack degrades over time and is expensive to replace through Polaris. Our kit replaces it with a higher-capacity, longer-lasting LiFePO4 battery with a 10-year warranty at a fraction of the OEM replacement cost.

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.
