A Yamaha electric golf cart can spend the morning on the course, carry passengers across a neighborhood in the afternoon and make one more trip around the property before dark. An aging lead-acid bank makes that schedule harder: voltage falls during use, recharging takes time, and battery watering becomes another chore. Epoch Yamaha lithium golf cart batteries replace that multi-battery bank with a properly matched LiFePO4 system designed for steadier output, more practical energy from the space and a simpler daily routine.
The Epoch Yamaha Lithium Golf Cart Batteries collection lists two complete 48V kits for compatible electric carts: 65Ah and 105Ah. Both use a single protected battery, provide Bluetooth monitoring and pair the pack with a lithium charger, dashboard gauge and 12V accessory converter. Yamaha Drive, G29 and Drive2 bodies vary by year and power system, so confirm the cart you own before selecting a kit.
Using space well means measuring it. The 65Ah and 105Ah batteries have different case dimensions, and a lid, seat base, hold-down or cable may reduce usable clearance. A correctly fitted battery can leave a tidier compartment and fewer exposed connections, but neither model should be called a universal drop-in for every Yamaha. Compare the physical battery bay and kit hardware before ordering.
Both collection models have a published 200A continuous discharge rating, IP67 battery enclosure, built-in battery management system and Bluetooth monitoring. The larger 105Ah option stores more energy for longer driving between charges; it does not increase the published continuous-current rating over the 65Ah kit. Choose for the route, the controller's demand and the space available.
| Epoch kit | Stored energy and case | A practical Yamaha use |
|---|---|---|
| 48V 65Ah complete kit | 3.33kWh; 66 lb; 17.2 × 14.3 × 7.5 in; included 48V 10A lithium charger. | Regular course loops, neighborhood trips and lighter daily driving when the 48V cart and tray match. |
| 48V 105Ah complete kit | 5.38kWh; 99 lb; 18.1 × 13.4 × 9.8 in; included 48V 15A lithium charger. | Longer property routes or repeated trips where extra stored energy and the larger case fit the cart. |
Epoch's 65Ah and standard 105Ah product pages have Yamaha 2007–2010 and Yamaha 2011+ configuration choices. Select the one that matches the cart's year and confirm what brackets and charging-port parts it includes. If you need a different case or more energy, a larger general golf-cart battery may call for a custom fit rather than the same Yamaha-specific installation.
Many electric Yamaha Drive/G29 and Drive2 lead-acid carts use a 48V traction system, often built from six 8V batteries. Begin by reading the vehicle identification and inspecting the existing bank, charger and battery-bay dimensions. Do not use a 48V kit on a 36V cart without a properly engineered conversion of the motor, controller and related equipment. Gas-powered Yamaha carts do not have the same traction battery to replace; factory-lithium Drive2 models also need a separate electrical and mounting assessment.
Check length, width, height, hold-down points, terminal location and cable reach. A cart with larger tires, a lift, repeated steep climbs or a modified controller may demand more continuous or peak current than a lightly used course cart. Compare those loads with the chosen battery's published limits, including regenerative charging if the drivetrain uses it. More amp-hours extend potential runtime, while output ratings determine whether the battery supports the load.
An old lead-acid charging profile may be unsuitable for LiFePO4. Each Yamaha-listed Epoch complete kit supplies a matching lithium charger, plus a gauge to read state of charge and a 48V-to-12V converter for appropriately sized lights, horn or other 12V accessories. Trace existing accessory connections before removing the lead-acid bank; do not leave a 12V load attached across part of a new traction battery.
Epoch offers a 2007–2010 Yamaha AC charge inlet and a 2011+ Drive/G29/Drive2 inlet for compatible factory cutouts. These are port accessories, not chargers. Verify the appropriate inlet and whether it is supplied with the selected kit. A neat exterior charging point is useful when the cart lives in a garage, maintenance shed or campground parking area.
Bluetooth on both Yamaha-listed Epoch batteries lets a nearby compatible phone view charge and battery readings through the Epoch app. Check before leaving for another nine holes, after a hilly neighborhood drive or when accessories have been running at a stop. The included dashboard gauge keeps the essential charge estimate visible from the driver's seat. Bluetooth communication is local; it is not a remote tracking service or a promise of a particular remaining mileage.
An integrated BMS provides model-specific protection against overcharge, over-discharge, excess current and temperature conditions. That protection supports reliability when the pack is charged and installed correctly, but a protective cutoff can still stop the cart. Leave a sensible charge reserve for the return trip and choose a battery whose output suits the controller. Epoch's IP67 rating applies to the battery enclosure; secure the pack, protect terminals and wiring, and follow the cart's maintenance schedule.
The two kits are listed for 3,500-plus cycles under their stated conditions and carry an 11-year limited warranty on the battery (5 years free repair or replacement, then 40% off MSRP on a replacement battery through Year 11; the included charger is covered for 2 years and the other kit components for 1 year). Actual service life depends on charging, temperature, operating loads and care. Compared with managing several aging flooded batteries, the simpler single-pack arrangement gives owners fewer battery connections to inspect and no cells to water before a busy day.
Do not combine lead-acid and lithium batteries in the new traction bank or assume every year uses the same wiring and charger connection. A Yamaha dealer or experienced golf-cart installer can review modified controllers, regenerative systems, unclear vehicle history and factory-lithium replacements. The goal is a battery that fits the vehicle as carefully as it fits the route.
Epoch's Yamaha lithium kits bring more routinely usable energy, steadier power and easier charge monitoring to a compatible lead-acid electric cart. The 65Ah kit suits shorter regular trips; the 105Ah kit offers more energy for longer or more frequent drives when its larger case fits. Both simplify watering and put the battery, charger, gauge and accessory power into one coordinated upgrade.

EPOCH 48v 105Ah Cart Battery
Only the best from EPOCH. Exceptional service and outstanding products.
Excellent Choice!
Replacement of the failing lead-acid batteries took a little longer than necessary. This is our first golf cart (new-ish Club Car Precedent bought it used about a year and a half ago). I hadn't realized before that the headlight and tail/brake lights were powered by a range of 12-48V, so the cart had no 12V accessories. Also, the cart came with a smart lead-acid battery charger so there was no on-board computer (OBC to control charging) to remove as shown on many YouTube videos. Once I figured all that out, installation went smoothly. With the new lithium battery, the cart is more responsive to throttle input. Enough, in fact, that we noticed that the motor control output regulator (MCOR, really just a throttle position sensor) had some flaky spots. An OEM replacement MCOR fixed that. So, no more lead-acid battery watering and cleaning. The weight loss program has shed about 300 pounds. It's now faster uphill. The cart is used almost daily for around .5 to 4 miles, and we charge the battery only about once a week instead of after every ride. Wife is happy, so I am happy.
