Smooth Installation, Huge Upgrade

Swapped into my Badboy buggy in under an hour. The cheap packs I tried before would cut out during heavy use; this Fleet Lithium pack never throttles. I get about 40-44 miles on flat courses.

Powerful and Reliable

I installed this pack in my Textron Prowler EV two months ago what a difference! Other cheap lithium packs would randomly shut down mid-ride, but this one delivers consistent power. I'm regularly seeing 42 miles per charge, though it varies with terrain and load.

10-Year Warranty Sealed the Deal

I own a Badboy buggy and cheap lithium packs always failed within months. This bundle's decade-long warranty, plus the protective cell gap, ensure it won't quit on me. I average about 41-46 miles depending on conditions.

No More Voltage Sag

In my Badboy buggy, heavy hills used to kill my cheap pack. With this bundle I maintain steady power and get 40+ miles before needing a recharge.

Range Exceeded My Expectations

Installed in my Badboy buggy, I've gotten a solid 44 miles on a single charge cheap packs I tried would die at 25-30. Smooth operation and zero shutdowns even under load.

Impressive Cold-Weather Performance

Living in Wisconsin, I needed reliable heat. Other cheap packs shut off when temps dipped, but the built-in heating elements on this bundle keep my Badboy buggy running smoothly. I've been hitting around 45 miles per charge, depending on usage.

Will it fit in a 64v stealth Apache 4x4

Fleet L.-.H.P.L.B.

Not as a direct drop-in because this battery is 76.8V and the Apache is a 64V system. We can still help with the conversion—send us the controller information and battery-tray size, and we’ll match the correct Fleet Lithium setup.

C
Customer

How does this battery hold up in cold weather? Our current ECO battery will not charge in temperatures under 30 Degrees.

Fleet L.-.H.P.L.B.

It does very well in cold weather. The built-in heater warms the battery automatically when charging below freezing, so it can still charge in the conditions that cause many lithium batteries to shut off. It is also rated to discharge down to -4°F.

Amazing Product, Amazing Customer Service

The customer service and the battery itself from Fleet Lithium is unbeatable. One of the best experiences as a customer I have ever had. They stand by their product and help you every step of the way to ensure you are happy in your purchase. The install was easy once you know where everything is supposed to go and the battery has performed flawlessly in my Bad Boy Recoil since installation. It made it a lot lighter and the buggy is obviously quicker now and I was able to ride it around the farm for hours in fast mode the other day and only used 25% of the battery carrying a buddy and myself. It is really amazing.

Awesome kit for cold weather climate

Awesome kit. We Live in a very cold climate, our ranger gets a ton of use year round and especially during the winter so the cold weather performance was a must for us. We've had the kit installed for about a year now and it's been perfect. Customer service has been super helpful the one or two times we had questions and we've got a couple of neighbors who run the kits as well and they say the same thing. Kevin and his crew are really top notch!

About Fleet Lithium

Built for demanding applications. Ready for everyday use.

Fleet Lithium develops high-output LiFePO4 battery systems for golf carts, LSVs, UTVs, marine, RV, and off-grid applications. We combine serious power capability with application-specific fitment, complete conversion components, and direct technical support.

Why Fleet is in our name

Fleet Lithium was built around equipment that gets used hard and cannot afford unreliable power.

Fleet Lithium was built around equipment that gets used hard and cannot afford unreliable power. Government fleets, rental operators, farms, hunting properties, and utility vehicles were our proving ground—not the modified-cart trend.

Those demanding applications shaped our approach from the beginning: build batteries with the power, control, and durability required for heavy daily use. That same overbuilt approach now serves individual golf cart, LSV, UTV, boat, RV, and off-grid customers who simply want a system they can depend on.

More than a battery in a box

A successful lithium conversion takes more than matching voltage and amp-hours.

Battery output, controller demand, charger programming, mounting, cabling, vehicle electronics, and communication protocols all have to work together. Fleet Lithium develops complete systems around the application so customers and installers do not have to piece together a conversion and hope the components are compatible.

Depending on the application, a Fleet Lithium solution may include the battery, matched charger, mounting hardware, cables, gauge or display integration, programming, installation guidance, and direct technical support.

Power and control built into the system

Fleet Lithium’s current NexGen battery management platform is rated for 300 amps of continuous discharge and up to 800 amps of peak output. It is designed to support real controller demand without treating every short power surge as an overload.

Select Fleet Lithium systems also support features such as OEM CAN-bus integration, cold-weather charging automation, Bluetooth monitoring, and GPS or geofencing for fleet security and operational control. These capabilities are application-dependent—not included with every battery.

  • 300A continuous / 800A peak surge discharge
  • OEM CAN-bus integration on select systems
  • Cold-weather charging, Bluetooth, GPS/geofencing where applicable

The application matters as much as the voltage

Two vehicles can use the same nominal voltage and still require completely different batteries, mounting solutions, chargers, cables, programming, or controller considerations.

Fleet Lithium researches vehicle generations, battery compartments, electrical architecture, controller demand, and charging requirements to develop application-specific configurations. Where fitment or installation requirements are verified, we document them clearly. Where additional validation is still required, we do not present an assumption as a confirmed fit.

Support and Warranty

Support from people who understand the entire system

Our support does not stop at the battery terminals. We help customers work through the battery, BMS, charger, controller, vehicle wiring, programming, and installation as one connected system.

Customers have direct access to technical support, product specifications, installation information, troubleshooting resources, warranty registration, and claims assistance.

Fleet Lithium Promise Series packs are backed by a 10-year warranty.

Built for the way you actually use it

Whether you manage a working fleet, operate equipment on a farm, hunt remote property, commute in an LSV, cruise in a golf cart, spend the day on the water, or need dependable off-grid power, Fleet Lithium is built around the application—not just the battery specification.
