Wattcycle Newest 51.2V 105AH Steel Golf Cart Battery For Our Club Car Solar Cart
Wattcycle just released a new line of golf cart batteries and I was given a chance to get the first one to try. No app needed to control or monitor but also has Bluetooth and app monitoring. The most rugged and safest battery I have tried so far.
When winter chills set in, this Golf Cart Battery maintains dependable performance thanks to its intelligent low-temperature cut-off: charging pauses below 32 °F and resumes at 50 °F, while discharge remains available down to –4 °F. Encased in IP67-rated housing, it keeps out dust and water, and paired with UL94 V-0 fireproof materials, it delivers resilient power even in the most demanding conditions—so your lithium golf cart batteries stay ready, come rain, snow or sleet.
The WattCycle 51.2V 105Ah Golf Cart Battery features a smart external display that brings key metrics directly to your fingertips. At a glance, you can verify voltage, remaining capacity and temperature— so you can know the status information of your golf cart even without your phone. This on-board interface enhances user confidence and operational efficiency, making it one of the most intuitive golf cart batteries available. Moreover, after our tests, the data information on the screen is more accurate than that on the Bluetooth APP.
Whether you choose our dedicated 48 V/15 A charger, a solar array of 1.6 kW or greater paired with an MPPT controller, or a generator feeding an AC-DC converter, the WattCycle 48V (51.2V) 105 Ah Golf Cart Battery refreshes to full capacity in about 6.7 hours. This flexibility means you’re never tied to a single power source—simply plug in your golf cart battery charger, set up your solar rig, or fire up a generator, and you’ll be back on the course with minimal downtime.
The WattCycle 48V (51.2V) 105 Ah Golf Cart Battery measures 17.76″ × 13.19″ × 9.64″ and weighs just 103 lbs, conforming to standard industrial dimensions for effortless installation in today’s most popular 48 V systems. Designed as a true drop-in replacement, it integrates seamlessly with leading golf cart batteries from Club Car, E-Z-GO, Yamaha, Cushman, Star EV, Tomberlin and Icon EV—no adapters or modifications required. Whether you’re swapping out old lead-acid packs or upgrading to a high-capacity lithium solution, this 48 volt lithium golf cart battery delivers consistent power and long cycle life, all while fitting neatly into your existing compartment.
Beyond the fairway, this battery proves its versatility as a reliable energy reservoir for solar storage systems, RV electrical setups, marine applications and off-grid installations. As a true deep cycle lithium golf cart battery, it delivers consistent discharge profiles and long cycle life—but keep in mind it is not intended for engine cranking. Whether you’re integrating with a standard golf cart battery charger or pairing with renewable power arrays, this 48 volt golf cart battery adapts effortlessly to diverse power demands, giving you a single solution across multiple platforms.

Frequently Asked Questions
The battery is suitable for many compatible 48V golf carts, including selected Club Car, E-Z-GO, Yamaha, Cushman, Star EV, Tomberlin and ICON EV models.
Before ordering, confirm that your battery compartment can accommodate its 451 × 335 × 245mm dimensions and that your controller supports a 51.2V LiFePO₄ battery. If you are unsure, contact us with your cart brand, model, year and compartment measurements.
Yes. One compatible 51.2V 105Ah battery can replace a complete 48V lead-acid bank, such as eight 6V, six 8V or four 12V batteries.
Remove all existing lead-acid batteries before installation and never mix lithium with lead-acid batteries. Some carts may require a hold-down bracket, cable adaptor, connector modification or onboard-charger bypass.
The battery stores 5.376kWh of energy, providing extended runtime for golf courses, neighbourhood driving and utility use. It also offers approximately 5% more energy than a 100Ah battery.
Actual range depends on the cart model, motor, controller, terrain, speed, passenger load, tyre pressure and accessories. Contact us with your vehicle details if you need a more specific runtime estimate.
Use a 58.4V LiFePO₄ charger with a CC/CV charging profile. The optional 48V 15A charger takes approximately 7 hours to charge the battery from empty.
Do not use the original lead-acid charger unless its charging voltage and profile have been confirmed as LiFePO₄-compatible. Select Battery + Charger when ordering if you require the compatible charger.
The built-in 200A smart BMS supports up to 10.24kW continuous output and 600A peak current for up to 30 seconds, with protection against overcharge, over-discharge, over-current, short circuits and abnormal temperatures.
Battery status can be checked through the Bluetooth App and intelligent battery display. The IP67-rated enclosure provides additional protection against dust and water. The battery includes a 5-year warranty, extendable to a total of 7 years after product registration.
