The Ultimate Hassle-Free Lithium Upgrade
A LiFePO4 conversion kit that turns a multi-battery 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 LiFePO4 battery that needs no watering or acid service, designed for everyday neighborhood, course, campground, utility, and fleet use.
A complete conversion kit in one box
Battery, charger and cord, gauge, remote switch, 12V converter, charge port plug and mounting hardware.
The kit includes the 36V 100Ah LiFePO4 battery, a 36V 15A onboard lithium charger with a 10 ft heavy-duty extension cord, a digital Bluetooth battery gauge, a 6 ft remote on/off switch with wiring harness, a fused 36V to 12V converter (25A) with a key-on wire, a cart-specific charge port plug, and cart-specific mounting hardware. That means you are not forced to hunt down the most important conversion accessories separately after checkout. The main fuse or DC-rated breaker for the battery cables is not part of the kit; install one as close as practical to the battery positive terminal.
Configurations for EZGO TXT, Club Car DS, and more
Built for popular 36V golf cart chassis and configuration-specific installations.
Choose the EZGO TXT, Club Car DS, or Other configuration to match your cart; Other covers Yamaha and other compatible 36V carts. 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
Dust-tight and protected against temporary immersion to 1 m for 30 minutes.
The IP67 enclosure is dust-tight and protected against temporary immersion up to 1 m for 30 minutes. It is not rated for water jets or pressure washing: mount the battery securely, protect it from physical damage, keep it away from long-term standing water, and inspect it after any immersion.
Bluetooth tracking and 11-year peace of mind
Smart state-of-charge visibility from your phone and from the included gauge.
The battery’s built-in Bluetooth connects to the free Epoch Li-Ion app for iOS and Android, so you can view state of charge, voltage, current, temperature, battery health, and warnings on your phone. The included digital Bluetooth gauge gives at-a-glance dashboard visibility, while the 11-year limited warranty (5 years of free repair or replacement, then 40% off MSRP on a replacement battery through Year 11; register within 90 days or keep your proof of purchase) supports long-term ownership confidence.

Conversion kit features
High-output lithium performance with the core accessories needed for a cleaner 36V upgrade.
Included kit components
Core parts for a complete 36V lithium golf cart battery upgrade.
Specifications
Full technical details, dimensions, weight, kit contents, and recommended charging settings.
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. The included charger charges the battery from empty in about 7 hours through the cart’s charge port, using the supplied 10 ft cord and a standard 120V outlet.
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.
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 36V 15A onboard lithium charger with a 10 ft heavy-duty extension cord, and it charges the battery from empty in about 7 hours. 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 should be done by an authorized mechanic or technician, following the steps in the user manual: remove the old lead-acid batteries, fit the cart-specific mounting hardware, install the charger, replace the cart’s factory charging receptacle with the supplied charge port plug (required for safety), mount the gauge and remote on/off switch on the dash, route the wiring harness, secure the battery, connect the charger leads and the cart’s main cables observing polarity, and install the 12V converter with its key-on wire. Then switch the battery on, confirm the gauge shows the state of charge, and charge it before first use if the charge is low. A main fuse or DC-rated breaker close to the battery positive terminal is required and is not part of the kit.
What kind of range can I expect from the 100Ah battery?
Range varies with terrain, tire size, cart weight, passengers, controller settings, motor upgrades, and driving style. Epoch estimates roughly 30 to 40 miles per charge for many standard 36V golf carts. For more range, two matched batteries can be connected in parallel (200Ah) with balanced cabling, proper fusing, and compatible charging equipment.
How long does it take to charge, and how do I plug in?
About 7 hours from empty with the included 36V 15A onboard lithium charger. The charger is powered through the cart’s charge port: the kit’s cart-specific charge port plug replaces the factory lead-acid receptacle (replacing it is required for safety), and the included 10 ft heavy-duty extension cord connects the charge port to a standard 120V outlet. If the charger stays connected, it restarts charging when the state of charge drops below about 95%.
Can I charge the battery in freezing weather?
No. This battery is not self-heated, and the BMS blocks charging outside 0°C to 55°C (32°F to 131°F), so let a cold battery warm above freezing before charging. It can discharge from -10°C to 55°C (14°F to 131°F).
Do I need to add water or perform maintenance on this battery?
No watering or acid service. The battery is maintenance-free compared with lead-acid: you do not need to check acid levels, add water, or clean acid residue. Routine inspections keep it operating safely: check the case, terminals, cables, fuses, and mounting hardware before each use, terminal tightness and cable condition monthly, the state of charge at least every 3 months in storage, and torque, wiring, protection devices, and charger settings once a year.
Can I connect two 36V 100Ah batteries together for more range?
Yes, in parallel only. This model supports up to two batteries in parallel (200Ah) for longer runtime. Do not wire these batteries in series to increase voltage beyond the 36V system class. Use matched BB38100A-Kit batteries of similar age, condition, and firmware at the same state of charge, with balanced cabling, proper fusing, and compatible charging equipment.
Will this battery work in EZGO, Club Car, and Yamaha golf carts?
This kit is offered in EZGO TXT, Club Car DS, and Other configurations; Yamaha and other compatible 36V carts use the Other configuration. Fitment is not universal: confirm that the battery bay fits the 14.6 × 13.4 × 9.9 in case, and check controller compatibility, cable length, charger connection, gauge location, and mounting method for your exact model year before ordering or installing.
