Run your 72V cart on one sealed lithium battery. The Epoch 72V 105Ah LiFePO4 Golf Cart Conversion Kit replaces the lead-acid bank in a 72V golf cart, custom build or neighborhood vehicle with a single 132 lb battery storing 7.39kWh. It's rated 70.4V nominal with 250A continuous output, and the kit includes a 72V 15A lithium charger, a Bluetooth battery gauge and a 12V converter for your lights and accessories.
*Epoch says performance users often report 40 to 50 miles per charge in favorable conditions. This is guidance, not a rating. Terrain, load, tire size, motor, controller programming and driving style all affect real-world range.
🛺 Will It Fit My Cart?
This kit comes in one version. There's no cart selector, and it doesn't include cart-specific mounting brackets. It's built for vehicles that already run a 72V system. Epoch lists it for:
- 72V golf carts (Club Car, EZGO & Yamaha platforms when fitment matches)
- Custom & high-performance 72V builds
- 72V neighborhood electric vehicles (NEVs / LSVs)
- 72V utility vehicles
- Aftermarket 72V motor & controller setups within the BMS limits
- Your cart runs on 72V. This battery is 70.4V nominal and charges to 79.2V. It is not for 36V or 48V systems, and it can't be wired in series.
- Upgrading a 48V cart? Your controller, motor, solenoid and other high-voltage parts must be rated for 72V before this battery goes in.
- Your battery bay fits 21.7" L × 13.4" W × 9.9" H (550 × 340 × 250 mm), plus room for terminals and cables. The battery weighs 132 lb (60 kg) and mounts upright.
- Mounting brackets, tray and hold-down hardware are not included. You'll need hardware rated for 132 lb. Epoch sells a tray separately.
- Your controller's draw stays within 250A continuous (500A for 15 sec, 1,000A for 2 sec), with regen braking within 500A for 15 sec.
- Epoch's kit list doesn't include a charge port plug. Plan how the charger will connect to your cart's receptacle before install.
- Fitment isn't universal. Epoch recommends checking tray fit, terminal clearance, cable size, fuse protection and charger profile for your vehicle.
Why 72V Owners Make the Switch
One Battery Instead of a Full Bank
A single 132 lb battery replaces the whole 72V lead-acid bank, so there's less weight to haul and only one battery to wire and look after.
Power for High-Performance Builds
250A continuous with 500A (15 sec) and 1,000A (2 sec) bursts, plus up to 500A of regen charging for 15 sec. Voltage stays steady instead of sagging as the charge drops.
See Everything From Your Phone
The Epoch Li-Ion app shows state of charge, voltage, current, temperature and warnings. BMS firmware updates over the air.
Smart BMS Protection
Over/under-voltage, over-current, short circuit and temperature protection (ambient, cell and MOSFET), with built-in cell balancing and an imbalance alarm.
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). Rated for 3,500+ cycles.

Lithium vs. Your Old Lead-Acid Bank
| Epoch 72V 105Ah Kit | Typical Lead-Acid | |
|---|---|---|
| Watering & terminal cleaning | Never | Regularly |
| Number of batteries | 1 | Usually 6 to 12 |
| Weight | 132 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 72V 15A lithium charger. If left plugged in, it restarts when the battery drops below about 95%.
No Lead-Acid Chargers
Don't use your old charger unless it's specifically approved and programmed for LiFePO4 within Epoch's limits (79.2V max). Equalization and temperature compensation must be off.
Charge Above Freezing
Charging is rated 0°C to 55°C (32°F to 131°F), and the BMS blocks charging outside that range. 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. Gauge, converter 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. Storage outside Epoch's limits, leaving the battery uncharged for more than 3 months, or an unsecured battery isn't covered. Full terms at epochbatteries.com.
