The Ultimate Hassle-Free Lithium Upgrade
A LiFePO4 drop-in replacement kit that turns a messy lead-acid bank into one clean lithium power system.
Upgrading a 36V golf cart can feel intimidating when you are trying to match batteries, chargers, gauges, converters, cables, and fitment parts. This complete 36V golf cart conversion simplifies the process by consolidating multiple heavy, maintenance-heavy lead-acid batteries into one sealed LiFePO4 unit with the core accessories already included.
The result is a cleaner battery bay, fewer corrosion-prone connections, less battery maintenance, and more usable energy from a zero maintenance golf cart battery platform designed for everyday neighborhood, course, campground, utility, and fleet use.
Everything you need in one box
A lithium golf cart battery with charger, gauge, converter, and smart app monitoring.
The kit includes the 36V 100Ah LiFePO4 battery, a 36V 15A lithium charger, a dashboard battery gauge, and a 12V converter. That means you are not forced to hunt down the most important conversion accessories separately after checkout.
Drop-in fit for EZGO, Club Car, and Yamaha
Built for popular 36V golf cart chassis and configuration-specific installations.
Choose from available kit configurations such as EZGO TXT, Club Car DS, or Other to match your cart. The battery measures 14.6 in L × 13.4 in W × 9.9 in H, so always verify your tray, hold-down clearance, cable routing, charger port, controller requirements, and voltage reducer needs before installation.
IP67 waterproof golf cart battery
Sealed against dust, rain, splashes, and harsh cart environments.
The IP67-rated battery case helps protect the battery and BMS from moisture, dust, and everyday outdoor conditions. It is rated for temporary immersion, but it should still be mounted securely, protected from physical damage, and kept away from long-term standing water.
Bluetooth tracking and 11-year peace of mind
Smart state-of-charge visibility from your phone and from the included gauge.
The Bluetooth battery monitor connects to the Epoch app so you can view state of charge, voltage, current, and battery status from a compatible smartphone. The included battery gauge gives at-a-glance dashboard visibility, while the 11-year warranty supports long-term ownership confidence.

Charger and installation note
Use the included 36V LiFePO4 charger or another compatible lithium charging system programmed correctly.
Do not charge this battery with an old lead-acid charger unless that charger can be properly configured for a 36V LiFePO4 profile. The battery’s recommended bulk / absorption voltage is 42.6V – 43.2V, and equalization should be disabled.
This model is not self-heated. It includes low-temperature charge protection, but it should be charged within the specified 0°C to 55°C / 32°F to 131°F charging temperature range.
Why upgrade to Epoch LiFePO4?
More usable energy. Less maintenance. Longer service life.
LiFePO4 technology provides stable voltage output, long cycle life, fast charging capability, and maintenance-free operation. Compared with traditional lead-acid batteries, this Epoch lithium golf cart battery kit helps reduce clutter, eliminate acid maintenance, and provide stronger usable energy in a cleaner, smarter package.
Frequently asked questions
Epoch 36V 100Ah Golf Cart Battery Kit FAQs
Common questions about charging, installation, range, maintenance, and fitment.
Does this kit include the correct charger for my golf cart?
Yes. This complete kit includes a dedicated 36V 15A LiFePO4 charger. You do not need to purchase a separate charger, and you should stop using your old lead-acid charger because it will not properly charge a lithium battery.
How hard is it to install this lithium conversion kit?
Installation is designed to be straightforward for many DIY golf cart owners. Remove your old lead-acid batteries, place the single Epoch 100Ah battery into the tray using the appropriate kit hardware for your selected cart configuration, then connect the main positive and negative cables. Always verify cable routing, tray clearance, polarity, and charger compatibility before powering the cart.
What kind of range can I expect from the 100Ah battery?
Range varies based on terrain, tire size, cart weight, passengers, speed controller settings, motor upgrades, and driving style. In many standard 36V golf carts, a 100Ah lithium battery can provide roughly 30 to 40 miles per charge, while also reducing weight compared with a traditional lead-acid battery bank.
Do I need to add water or perform maintenance on this battery?
No. This LiFePO4 golf cart battery is sealed and maintenance-free. You do not need to check acid levels, add water, clean acid residue, or perform routine lead-acid battery service.
Can I connect two 36V 100Ah batteries together for more range?
Yes. This model supports up to two batteries in parallel, which can increase total capacity for longer runtime. Do not wire these batteries in series to increase voltage beyond the 36V system class. Use matched batteries, balanced cabling, proper fusing, and compatible charging equipment.
Will this battery work in EZGO, Club Car, and Yamaha golf carts?
This kit is offered with configuration options for EZGO TXT, Club Car DS, and other installations. Many 36V EZGO, Club Car, and Yamaha carts can be upgraded to lithium, but you should confirm tray dimensions, controller requirements, charger connection, voltage reducer needs, and cable clearance before ordering or installing.
