Updated October 26, 2026. Choosing a lithium golf cart battery starts with your vehicle's actual electrical system, battery compartment and charging connections. Match those first, then choose the capacity that suits your routes, passengers and workload.
Fleet Lithium brings together LiFePO4 power, battery monitoring and a 10-year warranty. Power you can Trust. Use this guide to plan your upgrade, then follow the current instructions for your exact vehicle and kit.

Which lithium battery fits your golf cart?
Confirm the make, model, year, original battery voltage and whether your vehicle left the factory with lead-acid or lithium batteries. A model name or matching nominal voltage alone does not establish compatibility. The controller, charger, accessory converter, battery mounting and any battery-to-vehicle communication must also match.
| Your confirmed vehicle system | Battery family to check | Before ordering |
|---|---|---|
| 36V lead-acid | Fleet 36V-class lithium | Use a kit and charger approved for that 36V vehicle. |
| 48V lead-acid | Fleet 51.2V nominal lithium | Confirm the exact model, bracket, charger interface and accessory supply. |
| 72V lead-acid | Fleet 76.8V nominal lithium | Confirm the vehicle's full-charge voltage compatibility and required wiring interfaces. |
| Factory lithium, 64V, hybrid or multiple independent battery banks | Exact-system confirmation required | Do not select a replacement by voltage or connector appearance alone. |
E-Z-GO
Identify whether you have a TXT, RXV or another E-Z-GO model, then confirm its original voltage and controller. TXT and RXV mounting and charging arrangements differ. A guide for one is not a wiring diagram for the other. Use the matching installation guide and keep the vehicle's charging safety functions working.
Club Car
Confirm DS, Precedent, Tempo, Onward or Carryall, along with the battery system and charger arrangement. Some lead-acid vehicles use an onboard charging computer; any bypass must follow the instructions for your specific kit and vehicle. Factory-lithium vehicles need separate compatibility confirmation, including any communication requirements.
Yamaha
Check the model code, not just the body style. G-series, Drive/G29, Drive2 and utility models need their own mounting and connection checks. Identify DC versus AC drive where applicable. Do not assume that instructions for a lead-acid Drive2 also cover a factory-lithium PowerTech Li vehicle.
Utility vehicles and hunting buggies
Polaris Ranger EV, Tracker EV, Textron Prowler EV, Bad Boy Recoil and Cushman Hauler models have different electrical and mounting arrangements. The Cushman Hauler PRO/PRO-X 72V manual does not cover a 48V Hauler. Never combine independent battery banks or change a vehicle's operating voltage using a general conversion article.

Choose capacity and check the space
Amp-hours help compare capacity within the same voltage family. Watt-hours compare stored energy: nominal voltage multiplied by amp-hours. More capacity can support longer use between charges, but range also depends on passengers, terrain, tires, speed, temperature and accessories. A mileage example is not a guarantee for your vehicle.
Current 51V 168Ah battery: model 51168
| Nominal voltage | 51.2V |
|---|---|
| Capacity | 168Ah |
| Nominal stored energy | Approximately 8.60kWh |
| Case dimensions, length × width × height | 19.45 × 12.60 × 11.22 inches |
| Battery weight | Approximately 154lb / 70kg |
| Enclosure rating | IP65 |
These measurements apply to the current model 51168 specification. Confirm the label and case revision on your supplied battery, and leave space for terminals, cables, the bracket and service access. Older 160Ah and earlier case specifications are not a substitute for measuring the current pack. Match current limits and protection settings to the exact battery/BMS revision; do not program a controller from a generic comparison table.
Shop the 51V 168Ah battery bundle or view the 51V 168Ah battery. Check each listing's included components. A universal battery bundle is different from a vehicle-specific mounting kit.
Plan the installation before removing the old batteries
- Download the right manual. Read its model coverage, exclusions and parts requirements alongside your vehicle manual and the instructions supplied with the battery, charger and bracket.
- Record the original connections. Photograph and label the main cables, accessory feeds, charger connectors and small control wires. Follow the vehicle's shutdown and isolation procedure with the charger unplugged before disconnecting the old bank.
- Use the specified mount. Confirm that the actual bracket, battery and chassis match the kit instructions. Do not drill the battery case, cut supports or copy another vehicle's mounting layout.
- Keep low-voltage accessories on their correct supply. Lights, radios and other 12V equipment need a suitable converter or the approved original accessory supply. Never connect a 12V accessory directly to the main battery terminals. Check converter input rating against the battery's full-charge voltage.
- Match the charger and its safety connections. Use the approved lithium charging profile and connection arrangement. Preserve the required drive-inhibit function. Do not guess at unidentified small wires or bridge a connector to make the vehicle move.
- Use the supplied connection specifications. Cable size, fuses, terminal hardware, tightening torque and protection settings depend on the exact components. This overview does not supply a universal torque or pinout.
- Inspect before your first charge and drive. Secure and protect the wiring, check polarity and mounting, and follow the manual's commissioning sequence. Confirm the gauge, charger and accessories work correctly before a controlled, low-speed test. Stop using or charging the vehicle if you notice unexpected heat, a burning smell, smoke or damaged wiring.
Compare complete conversion systems
Compare the delivered kit, not just the battery's price. Check the exact bracket, charger, cables, gauge, accessory converter and vehicle interface included. Review current specifications, warranty terms and installation support for the models you are comparing. Heating, monitoring, communication and parallel-pack capability must be confirmed for the exact battery revision.
A supported installation makes the difference: the battery fits securely, the charging system works correctly and your accessories receive the voltage they need. Fleet Lithium's download library and support team help you work through those details.
Common lithium conversion questions
Can I use my old lead-acid charger?
Only use a charger and profile explicitly approved for the supplied lithium battery. A plug that fits does not establish compatibility. Follow your kit's charger instructions.
Will lithium make my golf cart faster?
Reduced battery weight and steadier voltage can change how the vehicle feels under load. Top speed still depends on its motor, controller, gearing and configuration. Do not increase voltage or change controller settings without exact-system approval.
Can I add another battery later?
Only use an approved parallel arrangement for the exact battery models and revisions. Confirm matching requirements, state of charge, cables, protection and mounting before connecting packs. A BMS does not eliminate those requirements.
What maintenance remains?
You no longer need to water lead-acid cells. Continue the inspections, cleaning, charging and storage care described in your Fleet Lithium manual. Check for loose or damaged connections and keep the battery securely mounted.
