Swap a heavy 36V lead-acid set for one sealed lithium battery. The Epoch 36V LiFePO4 Golf Cart Kit replaces the six 6V batteries in a typical 36V cart with a single 81 lb battery storing 3.84kWh. The kit comes with a 36V 15A lithium charger, a Bluetooth dash gauge, a fused 36V-to-12V converter and the charge port plug and mounting hardware for your cart, in EZGO TXT, Club Car DS or Other (Yamaha and other 36V carts) versions.
*Epoch estimate for many standard 36V carts. Terrain, load, tire size, controller settings and driving style all affect real-world range.
🛺 Will It Fit My Cart?
Choose EZGO TXT, Club Car DS or Other above so you get the matching charge port plug and mounting hardware. Epoch lists this kit for:
- EZGO TXT (36V)
- Club Car DS (36V)
- Yamaha 36V carts (choose Other)
- Other compatible 36V golf carts
- 36V NEVs & utility vehicles
- Your cart runs on 36V (usually six 6V lead-acid batteries). This kit is not for 48V carts.
- Your battery bay fits 14.6" L × 13.4" W × 9.9" H (370 × 340 × 250 mm), plus room for cables. The battery weighs 81 lb (37 kg) and mounts upright.
- Your controller's draw stays within 200A continuous (300A for 15 sec, 700A for 2 sec).
- Your 12V accessories (lights, radio, USB) total 25A or less on the included converter.
- The 6 ft switch harness reaches your dash. Stretched carts may need the 13 ft harness (sold separately).
- Fitment isn't universal. Epoch recommends confirming bay size, controller, cable length, charger connection and gauge location for your model year.
Why Cart Owners Make the Switch
Hundreds of Pounds Lighter
One 81 lb battery in place of a full lead-acid set, so the cart carries less dead weight and is easier on turf and suspension.
Strong, Steady Power
200A continuous with 300A (15 sec) and 700A (2 sec) bursts, and up to 300A of regen charging. Power stays steady instead of fading as the charge drops.
See Everything From Your Phone
The Epoch Li-Ion app shows state of charge, voltage, current, temperature and alarms. BMS firmware updates over the air.
Smart BMS Protection
Over/under-voltage, over-current, short circuit and temperature protection (including MOSFET temperature), with built-in cell balancing.
Zero Routine Maintenance
No watering, no acid, no corroded terminals. Charge after use and keep driving.
Built Tough
Stainless steel case rated IP67: dust-tight and protected against temporary immersion (1 m for 30 min).

Lithium vs. Your Old Lead-Acid Pack
| Epoch 36V Lithium Kit | Typical Lead-Acid | |
|---|---|---|
| Watering & terminal cleaning | Never | Regularly |
| Number of batteries | 1 | Usually 6 |
| Weight | 81 lb | Several hundred lb |
| Power as charge drops | Steady until nearly empty | Fades as voltage sags |
| Phone monitoring | Yes, via Bluetooth | No |
| Warranty | 11-year limited | Usually 1–2 years |
🔌 Charging Made Simple
About 7 Hours, Empty to Full
With the included 36V 15A charger and 10 ft cord from a standard 120V outlet. Partial top-offs are fine.
No Lead-Acid Chargers
Don't use your old charger unless it can be set to a 36V LiFePO4 profile. Equalization must be off. Settings for other chargers are in the spec table.
Charge Above Freezing
Charging is rated 0°C to 55°C (32°F to 131°F). There's no internal heater, so let a cold battery warm up first.
Low-Charge Alerts
Below 20%, the gauge bars flash and the buzzer sounds. Charge after each day's use, or at least weekly with light use.
🛡️ 11-Year Limited Warranty
Charger: 2 years free repair or replacement. Gauge, converter, brackets and other kit parts: 1 year. Register with Epoch within 90 days of purchase or keep your proof of purchase (otherwise coverage starts from the manufacturing date). Non-transferable. Full terms at epochbatteries.com.
