How It Compares

A comparison of the Eco Battery 51V 160Ah GEN3 against common Polaris Ranger EV battery options:

Eco Battery 51V 160Ah vs Eco Battery 51V 105Ah:

Single 51V 160Ah vs Dual 51V 105Ah:

• Single 160Ah: Simpler install, one BMS to manage, drops the most weight from the cart, leaves space in the battery bay for storage. Best for most Polaris Ranger EV owners.
• Dual 105Ah: Slightly more total range due to higher combined capacity. Two BMS units that operate independently. More complex install. Useful when an existing 105Ah owner wants to add capacity later.

Eco Battery 51V 160Ah vs Single 12V Drop-In Lithium Batteries:

• BMS Coordination: Four 12V drop-ins each have their own BMS, and those BMSs do not communicate. Under heavy Polaris Ranger EV load, the weakest BMS shuts down first and stops the cart. The Eco 160Ah uses a single BMS sized for the application.
• Continuous Current Rating: Most Amazon-grade 12V drop-ins are rated 100A to 200A continuous. The Polaris Ranger EV draws more than that on hills. The Eco 160Ah is rated 250A continuous.
• Fitment: Drop-ins require fabricated brackets to fit the Polaris tray. The Eco bundle includes the A-8172 Polaris-specific mount.
• Warranty: Eco Battery provides a Limited Lifetime warranty backed by US support. Most drop-ins carry shorter warranties or none at all.

Eco Battery 51V 160Ah vs Factory Polaris Lead-Acid (8 x 12V 155Ah):

• Usable Capacity: Lithium delivers approximately twice the usable kWh because depth of discharge is 90%+ versus roughly 50% for lead acid.
• Weight: 165 lbs vs approximately 700 lbs (535 lb weight savings).
• Charge Time: 3.5 hours vs 9+ hours.
• Maintenance: Zero vs monthly watering, terminal cleaning, and equalizing.
• Lifespan: Approximately 10 years vs 3 to 5 years for lead acid.
• Voltage Sag: Lithium holds steady voltage from 90% to 10% state of charge. Lead acid sags noticeably as it discharges, reducing performance late in a charge cycle.

Installation

The Eco Battery 51V 160Ah GEN3 conversion is designed as a drop-in upgrade for the Polaris Ranger EV. Most owners with basic mechanical skills complete the install in 3 to 5 hours. The majority of that time is spent removing the eight factory lead-acid batteries.

Installation Steps:

• Disconnect the main positive and negative cables and remove all eight factory lead-acid batteries from the Polaris Ranger EV
• Clean the battery tray and inspect cables for corrosion (replace any compromised cables)
• Install the A-8172 Polaris-specific mounting bracket in the factory tray
• Set the 51V 160Ah lithium battery into the bracket and secure it with the A-8016 flange supports
• Connect main positive and negative cables directly to the lithium battery terminals
• Mount the A-4012 quick-connect charge port and connect the included harness
• Install the A-3109 CAN LCD state-of-charge meter in place of the factory gauge
• Wire and mount the A-4220 remote wake-up button in a convenient location
• Power on the system, pair the EB Power app via Bluetooth, and run the recommended firmware update
• Test the cart at low speed before full use

Polaris Ranger EV-Specific Install Notes:

• Sevcon 12V Converter: The Polaris Ranger EV has its own factory Sevcon 48V-to-12V converter under the hood that powers headlights, switches, and the rear solenoid. Continue using it. No additional 12V converter is needed.
• Pink Wires: The two small pink wires with 2A fuses that previously tapped 12V off the lead-acid pack should be capped and zip-tied out of the way. They powered the lead-acid charge indicator only and are not needed with the new CAN LCD gauge.
• 2015 and Newer Rangers: Once the factory Delta-Q charger is removed, 2015+ Polaris Ranger EVs will not run unless the two ground wires inside the factory charger's molex connector are jumped. The installation guide covers this step.
• Pilot Car Upgrades: If your Ranger has a Pilot Car aftermarket upgrade, contact Pilot Car for cart-side programming to match the Eco Battery profile.
• Factory Lithium Variants (2016 / 2018 Li-Ion): The Eco 160Ah bundle is also compatible as a direct replacement for the factory Polaris lithium pack on these model years.

Charger and BMS

The Eco Battery 51V 160Ah GEN3 bundle includes the A-1055 38V to 51V 15A CAN charger, matched to the GEN3 battery. The charger and the battery's Battery Management System (BMS) communicate over CAN bus during the entire charge cycle. The BMS tells the charger when each cell is balanced and when to taper or shut off current.

What You Do Not Need to Do:

• Reprogram or modify the factory Polaris Delta-Q charger
• Ship the Delta-Q to Flight Systems, FSIP, or any third party for a lithium algorithm
• Rent or purchase a Delta-Q programming tool
• Reprogram the Sevcon motor controller
• Send the controller out for any modification

BMS Protections Included:

• Overvoltage cutoff (per cell and pack-level)
• Undervoltage cutoff to prevent deep discharge damage
• Overcurrent protection
• Short-circuit protection
• Multiple cell-level temperature sensors
• Active cell balancing during every charge cycle
• Low-temperature charge lockout (prevents charging below 32°F)
• Sleep mode for long-term storage
• Remote wake-up via button or charger connection
• Over-the-air firmware updates through the EB Power Bluetooth app

Charging from a fully discharged state takes approximately 3.5 hours. LiFePO4 does not need to be topped off between uses, has no memory effect, and is not damaged by partial charges. Storing the battery at 40 to 60% state of charge is optimal for long-term storage.

Cold Weather Performance

LiFePO4 batteries discharge reliably in cold weather but should not be charged below freezing. The Eco Battery 51V 160Ah GEN3 is rated to discharge between -4°F and 140°F and to charge between 32°F and 130°F.

Cold Weather Best Practices for Polaris Ranger EV Owners:

• Charge the battery as soon as you finish using it, while the cells are still warm internally from operation
• For overnight charging below freezing, store the Ranger in a garage that stays above 32°F
• The BMS automatically prevents charging when the battery is below freezing, protecting the cells from lithium plating damage
• Discharge performance gradually softens below 50°F but the battery remains fully functional down to -4°F
• For sub-freezing storage and outdoor charging, the Heated 160Ah GEN3 version is recommended

About the Heated 160Ah Upgrade: The heated version of this battery has integrated self-heating hardware. When the charger is plugged in and the battery temperature is below approximately 32°F, the BMS automatically activates internal heaters. Once the cells warm above freezing, normal charging begins. Heating runs only while the charger is connected. The heated version can be charged outdoors in temperatures as low as -4°F. Contact Lithium Battery Supply if you need a heated configuration.

If you regularly operate or store your Polaris Ranger EV in cold climates, contact us before ordering. We will confirm whether the standard 160Ah or a heated configuration is the better fit for your conditions.

Range and Performance

Real-world range on a Polaris Ranger EV with the Eco Battery 51V 160Ah GEN3 depends on terrain, load, tire size, speed, and temperature. The numbers below reflect typical results reported by Polaris Ranger EV owners running a single 160Ah configuration.

Expected Range by Use Case:

• Stock Ranger, flat terrain, light to moderate use: 50 to 60+ miles per charge
• Mixed work use, moderate hills: 40 to 50 miles per charge
• Hilly terrain, full bed, towing, or sustained 4WD off-road: 25 to 40 miles per charge
• Lifted carts with oversized tires: Expect 15 to 25% less range than the figures above

Performance Improvements vs Factory Lead-Acid:

• Voltage Stability: Lithium holds steady voltage from 90% to 10% state of charge. Hill climbs and acceleration feel the same at half charge as they do fully charged. Lead acid sags noticeably as it discharges.
• Acceleration: Approximately 535 lbs of weight removal results in quicker throttle response.
• Torque Under Load: The 250A continuous discharge rating delivers steady torque on hills and during towing without BMS cutbacks.
• Reduced Chassis Wear: Lower total vehicle weight reduces strain on the motor, controller, suspension, and frame.

Towing and Heavy-Use Notes:

• The Polaris Ranger EV is rated to tow up to 1,500 lbs. The Eco 160Ah handles this within the published continuous and peak discharge specs.
• For sustained towing on long grades, monitor the EB Power app for cell temperatures.
• If a single 160Ah is not enough for your duty cycle, a second 160Ah can be added in parallel for roughly double the runtime. Contact Us, Lithium Battery Supply, to spec a dual-battery configuration.
