When running high-draw 4WD hunting buggies like a Bad Boy Buggy or specifically a Tracker EV, amp-hogging dual-motor systems will instantly expose a weak battery setup. Upgrading to lithium isn’t just about dropping 300+ pounds of dead lead-acid weight, it’s about securing an unyielding power source that won’t sag or trip your BMS when you’re hub-deep in a mud hole or climbing steep inclines.
The Bolt Energy USA 73.6V 105Ah “POWER” Lithium Battery Kit stands out as the ultimate lithium conversion system on the market for heavy-duty off-road utility vehicles, the ideal Tracker EV lithium battery upgrade.
Standard 72V lithium packs typically use a basic 22-cell series configuration (22S). For a Tracker EV lithium battery upgrade, Bolt Energy steps up performance with an advanced 1P23S cell setup. That extra cell pushes nominal voltage to 73.6V and delivers 7.7kWh (7,728Wh) of usable power, giving you a noticeably higher voltage floor when your rig needs it most.
Tracker EV lithium battery upgrade – Bolt Energy USA 72V – 105Ah.
During aggressive trail tests in high-demand 4WD buggies, the Bolt Energy 73.6V system demonstrated incredible voltage hold:
Drivers report relentless torque throughout the entire run. By keeping the voltage floor high (holding ~76.1V at 82% SOC), the Bolt system delivers smooth, steady power all day long.
For your Tracker EV lithium battery upgrade, Bolt Energy’s kit doesn’t bottleneck your vehicle with thin wires or light-duty components. Designed specifically for high-amp installations, the full kit equips your Tracker EV or Bad Boy Buggy with total reliability:
One of the biggest advantages of choosing Bolt Energy USA for your Tracker EV lithium battery upgrade is total long-term peace of mind. Every battery pack comes backed by an industry-leading 12-Year Warranty paired with lifetime technical support directly from their Florida headquarters.
Whether you’re a DIYer looking to pick up a complete kit for a weekend garage install, or you want a turn-key professional conversion handled by local pros, we’ve got you covered:
The OEM battery configuration in a 72V Tracker EV (and Tracker Prowler EV) consists of nine heavy 8-volt flooded lead-acid batteries wired in series. This factory battery bank weighs approximately 550 to 600 lbs, requires constant water top-offs under the seats, and suffers from severe “voltage sag” under load.
A Tracker EV lithium battery upgrade to a single 72V 105Ah LiFePO4 lithium kit replaces all nine batteries with one unit weighing around 130 to 140 lbs. You instantly shed 400+ lbs of dead weight, eliminate battery watering and acid corrosion forever, and experience full, steady power output right up until the battery needs a charge.
Yes, provided you install a 72V Tracker EV lithium battery upgrade kit engineered specifically for high-torque electric UTVs. The Tracker EV utilizes a high-output 72V AC motor system (and 4WD engagement) that pulls high amperage when climbing steep hills, slogging through mud, or hauling heavy gear.
The 72V 105Ah kits we carry (such as Bolt Energy and Epoch) feature heavy-duty Battery Management Systems (BMS) rated for 200A to 300A continuous discharge and 500A to 800A peak surge output. This ensures your BMS won’t trip or shut off under heavy throttle or when engaging 4WD on rough terrain.
Part of your Tracker EV lithium battery upgrade includes shedding over 400 lbs of lead-acid weight, transforming the ride quality and handling of the Tracker EV:
Increased Ground Clearance: The suspension springs are no longer compressed under hundreds of pounds of lead, restoring factory ride height for clearing rocks, logs, and rutted trails.
Better Mud & Marsh Traversal: A lighter UTV sits on top of soft ground rather than sinking into deep mud holes.
Reduced Wear on Drivetrain Components: Lower vehicle weight significantly decreases wear and tear on CV axles, suspension bushings, brakes, and steering gear.
Yes. The Tracker EV lithium battery upgrade conversion kit includes a vehicle-specific mounting bracket system designed to secure the single lithium pack cleanly inside the factory battery compartment. The kit also comes complete with:
Custom-length 0 AWG heavy-duty battery cables.
A state-of-charge (SOC) digital battery gauge for your dashboard.
A 12V DC-DC converter to safely power factory lights, winches, and accessories.
A matched 72V high-speed lithium smart charger.
No. You must disconnected or bypass the factory lead-acid charger and use the dedicated 72V lithium smart charger included in your kit – this is a mandatory part of your Bolt Energy Tracker EV lithium battery upgrade.
Lead-acid chargers utilize multi-stage charging algorithms (designed for equalization and desulfation) that can overcharge lithium cells or trigger the battery’s BMS safety shutoff. The included lithium charger connects directly to the battery or your designated charge port, charging the 105Ah pack in 3 to 5 hours.
