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.
