WattCycle 48V 50Ah Bluetooth LiFePO₄ Battery with 100A BMS – For Golf Carts & Ride-On Mowers
- GC2-Style Fit for Easier Upgrades – Measuring 264 × 183 × 330.7 mm (10.4 × 7.2 × 13.02 in), the compact metal case is designed to fit many GC2-style battery compartments, helping simplify upgrades for compatible 48V golf carts. Please check the battery tray dimensions, terminal position and system voltage before ordering.
- Strong Acceleration and Hill-Climbing Output – Supports 2C continuous discharge through a built-in 100A BMS, delivering up to 5.12kW continuous output, with 150A for 30 seconds and 300A for 0.5 seconds. The high surge capability supports responsive take-off, steep climbs, heavier passenger loads and demanding utility use.
- 2.56kWh Per Battery, Scalable for Longer Runtime – Each battery provides 51.2V 50Ah / 2.56kWh of usable energy. In an approved parallel configuration, capacity can scale to 5.12kWh with 2 batteries, 7.68kWh with 3, or 10.24kWh with 4—ideal for longer golf-cart routes, resort fleets, farms, large properties and compatible 48V marine, RV or off-grid systems.
- Bluetooth Monitoring and Easy Storage Control – Built-in Bluetooth lets you check key battery information and alerts from your phone. The top-mounted physical ON/OFF switch makes long-term storage and maintenance easier, while the low self-discharge rate of ≤3% per month helps preserve charge between rounds or during seasonal storage.
- Durable Protection for Demanding Conditions – The rugged metal enclosure and IP54 dust- and splash-resistant design help protect the battery from vibration, dust and wet grass conditions. Integrated BMS temperature protection stops charging at approximately 0°C and discharging at approximately -20°C, with additional high-temperature protection.
- 6000-Cycle LiFePO₄ Performance – Delivers 6000 cycles at 80% depth of discharge, offering a significantly longer service life and lower replacement cost than conventional lead-acid batteries.
- Documented Safety and Compliance – Compliance documentation includes IEC 62619, UN 38.3, CE-EMC, FCC SDoC, CE-RoHS and CE-Battery, covering battery safety, transport testing, electromagnetic compatibility and restricted-substance requirements.
- 5-Year Warranty and Lifetime Support – Backed by a 5-year warranty and lifetime technical support from WattCycle, giving Australian golf-cart owners and fleet operators dependable support throughout the battery’s service life.
Free local shipping for all orders, except some areas need extra shipping cost.
Our batteries come with a 5-year warranty, which can be extended to 7 years total upon product registration. Accessories are covered by a 1-year warranty, and like-new (refurbished) batteries include a 1-year warranty.

- Affordable expansion solution including the Wattlink cable（Delta 2/3 series）.
- Ultra-lightweight and portable design weighing only 44 lbs.
- It is more convenient than 12V or 24V systems that require DIY voltage boosting, and more cost-effective than a 48V 100Ah setup.
Climb Stronger, Last Longer: WattCycle 51.2V Lithium Golf Cart Batteries
Upgrade your ride with WattCycle's drop-in 48V lithium golf cart batteries that fit standard trays with no modifications. Choose the standard BCI GC2 50Ah version featuring a 100A BMS (2C discharge) and a physical ON/OFF switch to prevent winter storage drain, or step up to the 105Ah version with a 250A BMS and Bluetooth monitoring for extended mileage. Both models provide reliable low-temperature protection and heavy-duty performance to eliminate power lag on steep hills.
Purchase Recommendation
If you want a lighter, space-saving BCI GC2 size 48V lithium golf cart battery for golf carts, electric marine motors, RVs, and off-grid systems. If you are converting from heavy lead-acid units and want a direct-fit solution with a physical ON/OFF switch for worry-free storage and daily operation, the WattCycle 48V 50Ah battery is your ready solution.
