Polaris Ranger EV
The Polaris Ranger EV runs eight 6V lead-acid batteries weighing roughly 700 pounds. These LiFePO4 conversion kits replace all eight with a single 51.2V lithium battery, removing close to 580 pounds and ending watering, equalizing and terminal corrosion for good.
We carry Lithium Rhino, Bolt Energy and Eco Battery kits for the 48V Ranger EV, 2010–2022, in capacities from 105Ah to 210Ah. Every kit includes the battery, a matched lithium charger, mounting hardware and a gauge. Free shipping to the contiguous U.S. If you are not sure which kit fits your vehicle, the guide below walks through it, or call our team at +1 (786) 321-3526.
Why upgrade your Polaris Ranger EV to lithium
A Ranger EV on original lead-acid batteries fights three problems at once. The pack loses voltage as it discharges, so the vehicle slows on hills and toward the end of a charge. The batteries need regular watering and terminal cleaning, and they corrode anyway. And at roughly 700 pounds, eight lead-acid batteries are dead weight that eats into range and torque.
A LiFePO4 lithium conversion solves all three. Lithium iron phosphate holds voltage nearly flat through the discharge curve, so the Ranger keeps full power and speed until it is nearly empty. There is no watering, no equalizing and no corrosion. And a single lithium pack weighs a fraction of the lead-acid bank it replaces, freeing up payload and improving acceleration and hill climbing.
For farmers, ranchers, property managers and hunting-land owners who depend on the vehicle every day, the practical result is less downtime, longer runtime between charges and a battery that lasts years longer than the pack it replaced.
Benefits of a lithium conversion
- Longer runtime and range. More usable capacity than lead-acid at the same voltage, with no voltage sag as the pack drains.
- More torque and better hill climbing. Flat voltage delivery means full power up grades and under load, not just on flat ground.
- Maintenance-free. No watering, no equalizing, no terminal corrosion. Install it and drive.
- Faster charging. LiFePO4 accepts a charge far faster than lead-acid and does not need a full cycle to stay healthy.
- Hundreds of pounds lighter. Improves payload, handling and efficiency.
- Bluetooth monitoring. A smart battery management system reports state of charge, cell voltage and temperature to a phone app.
- Longer lifespan. LiFePO4 packs are rated for thousands of cycles, typically outlasting several lead-acid replacements.
Why the Ranger EV is not a golf cart
This matters when choosing a battery, because a Ranger EV works far harder than a golf cart. Towing, plowing, hauling and climbing pull much more current than cruising a fairway. Ranger EV motors commonly draw 130 to 150 amps on moderate hills and can peak at 400 to 500 amps under heavy load.
That makes the battery management system's continuous amp rating as important as capacity. A battery with plenty of amp-hours but a conservative BMS can cut out under sustained load. If you tow, plow, haul or run hills regularly, weigh the discharge rating alongside the range figure, not just the capacity number.
Featured battery brands
Lithium Rhino
Lithium Rhino builds Ranger EV kits in 120Ah and 170Ah. The 170Ah is the heavy-duty option Ranger forums cross-shop for towing and plowing, with a 300A continuous, 800A peak BMS, self-heating built in, and a gauge that integrates with the Polaris factory dash. Its 8-year warranty covers cells, BMS and electronics, with full replacement for the first six years and a $500 deductible in years seven and eight, backed by lifetime U.S.-based support. Both capacities include a voltage reducer for 12V accessories.
Bolt Energy
Bolt Energy offers the Ranger EV kit in 105Ah and 210Ah (a dual 105Ah configuration), in standard and heated variants for cold climates. The slim battery uses a powder-coated steel enclosure rated IP66, a 250A BMS, Bluetooth and a Smart SOC meter. Bolt carries a 12-year limited manufacturer warranty, the longest of the three, and every kit includes a voltage reducer.
Eco Battery
Eco Battery's GEN3 Ranger EV bundles come in 105Ah, 150Ah and 160Ah. The GEN3 battery management system supports over-the-air firmware updates through Bluetooth and the Eco Battery app, and the CAN-enabled charger coordinates charging across the cells. Eco carries a limited lifetime warranty. Note that Eco Ranger EV bundles do not include a voltage reducer, so add one if you run 12V accessories.

Which capacity should you choose
Every kit here is 48V nominal, 51.2V actual. Capacity determines range; the BMS rating determines how hard you can work it. Terrain, load, tire pressure and driving style all affect real-world range.
| Capacity | Estimated range | Ideal user |
|---|---|---|
| 105Ah | 40–50 miles | Property maintenance, short daily rounds, light loads |
| 120Ah | 40–50 miles | Solo use, trail riding, farm rounds. 250A continuous, 500A peak |
| 150Ah / 160Ah | 60+ miles | Full work days, hills, hauling, all-day hunting |
| 170Ah | Up to 74 miles | Towing, plowing, steep terrain, commercial duty. 300A continuous, 800A peak, self-heating |
| 210Ah | Highest available | Maximum range and continuous-duty commercial and fleet use |
For property maintenance and farm rounds, 105Ah or 120Ah is usually plenty. For hunting land with hills, or a vehicle that hauls all day, step up to 150Ah or 160Ah. For towing, plowing or municipal and commercial fleets that run the Ranger hard from morning to night, the 170Ah and 210Ah are built for it. A larger pack adds weight and cost, so the biggest option is not automatically the right one.
What most Ranger EV owners choose
After fitting these kits on a lot of Ranger EVs, a clear pattern shows up. Most owners land on one of three, depending on how they use the vehicle:
| Pick | Kit | Why owners choose it |
|---|---|---|
| Most popular | Bolt Energy 105Ah Heated | The default choice for owners who work outdoors and charge in unheated garages or barns through winter. The heated battery and 12-year warranty are what win people over. |
| Best for more range | Eco Battery 160Ah | The step-up for longer work days, hills and hauling, and the one to pick if you are replacing a factory lithium pack and want more range than it gave you. |
| Best value | Lithium Rhino 120Ah | Strong capacity, 250A continuous BMS and an included voltage reducer at a competitive price. A good fit for solo use, trail riding and property rounds. |
If you tow or plow hard, look past these three at the higher discharge ratings, such as the Rhino 170Ah or Bolt 210Ah. Not sure which way to go? Call our team at +1 (786) 321-3526 and we will match the kit to how you actually use your Ranger.
Choosing by how you use it
Different work pulls different power. Property and grounds crews doing short daily rounds are well served by 105Ah or 120Ah. Farms and ranches that haul, spray or run long days lean toward 150Ah or 160Ah. Hunting-land owners covering rough terrain all day usually want the extra range of 160Ah. And anyone towing a trailer or running a plow should prioritize the higher-discharge 170Ah or 210Ah, where the BMS rating matters as much as the capacity.

Charging your Ranger EV after conversion
The Ranger EV shipped with an onboard Delta Q QuiQ charger set for lead-acid. That profile is not appropriate for LiFePO4 and cannot be used as-is. Every kit includes a lithium charger matched to its battery, and that is the charger to use. Eco Battery and Lithium Rhino chargers use CAN communication with the BMS so the charger and battery coordinate charging across the cells.
Frequently asked questions
LiFePO4 batteries are rated for thousands of charge cycles, which for most owners means well over ten years of service. That typically outlasts several sets of lead-acid batteries over the same period.
Yes. These kits are designed as direct replacements. You remove all eight 6V lead-acid batteries and install one 51.2V lithium pack using the existing battery bay and vehicle wiring.
No. The onboard Delta Q QuiQ charger is set for lead-acid, and that profile is not appropriate for LiFePO4. Each kit includes a lithium charger matched to its battery, and that is the charger to use.
Yes, the Ranger EV runs 12V accessories through a voltage reducer. Lithium Rhino and Bolt Energy kits include one. Eco Battery Ranger EV bundles do not, so add a reducer to your order if you run a winch, plow, lights or other 12V accessories.
Yes, powered through the voltage reducer. Keep an eye on total 12V draw, since a winch or plow motor pulls hard and the reducer has a fixed limit regardless of how much capacity the traction battery holds.
Each kit includes its own state-of-charge gauge matched to the lithium battery, and most also report to a phone app over Bluetooth. The Lithium Rhino 170Ah gauge integrates with the Polaris factory dash.
Most owners finish in two to four hours with basic hand tools. You remove the eight lead-acid batteries and mount one lithium pack. Mounting hardware and cabling are included. If you are not comfortable working with vehicle electrical systems, use a qualified technician.
Range depends on capacity and how the vehicle is used. A 105Ah or 120Ah kit delivers roughly 40 to 50 miles, 150Ah and 160Ah kits reach 60+ miles, and the 170Ah can reach up to 74 miles. Terrain, load, tire pressure and driving style all affect real-world range.
Look at the BMS continuous rating, not just capacity. Ranger EV motors draw 130 to 150 amps on moderate hills and can peak at 400 to 500 amps under load. For regular towing or plowing, choose a higher capacity with a stronger discharge rating, such as the 170Ah or 210Ah. For property rounds and trail use, 105Ah or 120Ah is usually enough.
Yes. The battery management system stops the charge when the pack is full, so a lithium battery on its matched charger can stay connected without overcharging. It is still good practice to unplug for long-term storage.
A standard LiFePO4 battery should not be charged below freezing. Eco Battery specifies charging above freezing and up to 130°F, with safe operation from −10°F to 140°F. For regular winter charging outdoors, choose a self-heating option. Bolt Energy heated kits warm the battery and begin normal charging at roughly 34°F, with the heater running only while the charger is connected. Lithium Rhino builds self-heating into the 170Ah and offers it as an upgrade on the 120Ah.
No. The Ranger XP Kinetic is a high-voltage vehicle on a different electrical architecture. These kits are for the 48V Ranger EV, which used eight 6V lead-acid batteries or a factory lithium battery.
Yes. Eco Battery states a 105Ah kit gives performance comparable to the factory lithium pack, and recommends 160Ah for owners who want more range than the original battery delivered.
The eight factory lead-acid batteries weigh roughly 700 pounds together. A single lithium pack replaces all of them, removing close to 580 pounds depending on the capacity chosen. That weight saving improves payload, handling and range.
No. The battery does not change the motor. Some Ranger EVs run warm in hot climates at low speed over long periods, and Polaris offers an EV motor cooling fan kit for this. It is a characteristic of the vehicle, not of the battery.
Bolt Energy carries a 12-year limited manufacturer warranty. Eco Battery carries a limited lifetime warranty on the battery. Lithium Rhino carries 8 years on the cells, BMS and electronics, with full replacement for the first six years and a $500 deductible in years seven and eight, backed by lifetime U.S.-based support.
