Product at a glance

This section gives you the core facts quickly so you can decide what matters most. You’ll get a compact, high-output 48V LiFePO4 battery kit designed specifically for mini golf carts and small trailers, with integrated monitoring and fast charging.

What’s included in the kit

You’ll receive the battery itself along with the accessories needed to get up and running. The kit includes a fast LiFePO4 charger, a 2.8-inch touchscreen monitor with communications ports and app support, anti-vibration bracket, and a carabiner for secure mounting.

Beyond the physical items, you’ll also get five years of after-sales support from Elefast and access to online technical support. You’ll appreciate the fast response promise (typically within 10 hours) for troubleshooting or warranty questions.

Design & form factor

The kit’s selling point is its MINI size, which was designed to fit into tighter battery compartments that traditional lithium replacements can’t. Compared to many other 48V lithium options, this battery reduces volume by roughly 20% while keeping the same capacity, so you won’t have to modify frame or wiring in most cases.

You’ll notice the cold-rolled steel shell and IP65 rating, which balance protection and compactness. The build is rugged but still intended for small-vehicle installation where space is limited.

Size comparison and fit

You’ll find this battery particularly helpful if your cart’s battery bay is narrow or shallow. In many mini golf carts and trailers, older lead-acid blocks don’t leave much clearance; the MINI size helps you avoid cutting or welding.

If you still have doubts about fitting, measure your battery tray and compare it to the product dimensions before purchasing. That simple step prevents surprises and saves you time during installation.

Battery cells and chemistry

The battery uses Grade A+ LiFePO4 cells arranged into 16 sets to produce a stable and safe energy pack. LiFePO4 chemistry is known for thermal stability, long cycle life, and consistent voltage under load, which is well-suited for vehicle applications like golf carts.

Because the cells are high-grade, you’ll see more predictable performance and a longer usable life compared with lower-tier battery packs. That matters when you push the cart on hilly courses, tow small trailers, or run additional accessories.

Energy, capacity and usable power

With a nominal energy around 5.12 kWh (51.2 V × 100 Ah), this pack offers plenty of usable power for most mini golf carts. You can expect a realistic usable capacity of about 80–90% depending on how conservative you want to be with depth-of-discharge (DOD), which still leaves you significantly more usable energy than typical lead-acid setups.

Because LiFePO4 tolerates deep discharges better than lead-acid, you’ll be able to use more of the pack without shortening its lifespan excessively. For most users, that translates into more range per charge and fewer interruptions during multi-round outings or work shifts.

Performance under load

The battery provides a 2C discharge rating, which translates to around 600 A continuous discharge and a peak surge capability up to 1000 A. You’ll get strong acceleration and reliable performance across uneven terrain or quick bursts of power that some electric motors demand.

Those high discharge figures reduce voltage sag when you launch from a stop or climb steep grades, so the cart will feel more responsive. The reliable high-current capability is one reason this battery works well for smaller carts and lightweight utility trailers.

Charger and monitoring

The included 58.4 V, 18 A LiFePO4 fast charger replenishes the pack in about 5.5 hours from empty to full under normal conditions. You’ll appreciate that the charger is sized to match the battery chemistry, which helps maintain health and cycle life.

The 2.8-inch touchscreen provides real-time readouts and control, while communication ports and the mobile app let you monitor temperature, cycle count, and SOC (state-of-charge) remotely. You’ll find this useful for preventive maintenance and for keeping an eye on the pack during long outings.

Touch monitor features

The touchscreen is compact but functional, showing essential metrics like voltage, current, SOC, temperature, and error codes. You’ll use the monitor to check health quickly and to access logging if you want to track long-term performance.

If you prefer remote access, the mobile app integration adds convenience and lets you share details with tech support if something looks off. That makes troubleshooting simpler than relying on opaque error lights alone.

BMS and safety features

A built-in 200 A BMS protects the battery from overcharge, over-discharge, overcurrent, overheating, and short circuits, giving you continuous protection in typical and harsh conditions. The pack also includes a low temperature protection mechanism so the battery won’t accept full charging at dangerously low temperatures.

You’ll find international safety certifications (IEC tested, CE, RoHS) that reflect both component-level quality and safer manufacturing practices. Combined with the steel shell and IP65 protection, that safety-focused design reduces the likelihood of catastrophic failures.

Mounting and installation

Installation is designed to be straightforward: no wiring changes are required for most 48V golf cart systems, which means you’ll be able to swap the battery without rewiring. The anti-vibration bracket and carabiner help keep the battery stable and prevent the cart’s metal structure from damaging the pack during use.

You should still take basic precautions: disconnect the cart, secure the battery properly, and double-check polarity before connecting. If your cart uses a unique connector, verify compatibility or have an adapter on hand.

Step-by-step installation (brief)

You’ll remove the existing batteries, fit the new MINI battery into the tray, secure the anti-vibration bracket, and connect the positive and negative leads per the manual. After connecting, power up the monitor and verify that the display shows normal voltage and SOC before driving.

If anything looks abnormal—unexpected error codes, unusual voltages, or communication failures—stop and consult support. Elefast’s 5-year after-sales and quick-response technical help are useful if you encounter setup issues.

Compatibility with carts and systems

This battery is compatible with Yamaha, E-Z-GO, Club Car, and most systems that accept a 48V pack, thanks to its nominal voltage and form factor. You won’t usually need to rewire or change controllers for small vehicles using standard 48V setups.

However, always confirm connector type and physical fit before ordering, especially if your cart has unusual modifications, aftermarket controllers, or additional electronics. That avoids compatibility surprises and ensures a smooth upgrade.

Durability and environmental resistance

The IP65-rated cold-rolled steel shell provides good protection against dust and low-pressure water jets, which is plenty for typical golf course and trail use. The anti-vibration mounting and reinforced structure also reduce mechanical stress from bumps and vibrations.

Remember that no battery is entirely immune to extreme conditions, so avoid submerging the pack or exposing it to sustained high-temperature environments. Proper mounting and occasional inspection will keep the battery performing and safe.

Cycle life and expected lifespan

Rated for up to 8000+ deep cycles, this LiFePO4 pack promises many years of reliable service under normal use. In practice, you can expect over a decade of usable life if you manage charging and storage properly, which dramatically reduces lifetime cost compared with lead-acid banks.

You’ll keep the pack healthier by avoiding prolonged full discharges and by following the storage advice: charge to about 80% and perform a deep-discharge cycle now and then to calibrate SOC when storing long-term. That simple routine helps maintain the battery management system’s accuracy and overall lifespan.

Real-world runtime and range examples

You can estimate run-time by dividing energy (Wh) by average motor draw (W). With roughly 5120 Wh nominal, here are some sample scenarios to help you plan trips and charging:

• If your cart averages 400 W while cruising, you’ll get roughly 12–13 hours of runtime under ideal conditions. That’s enough for multiple rounds or a full day of light use.
• At 1000 W average draw (more aggressive use, hills, or heavier loads), you’ll see about 4–5 hours of runtime. That still covers many typical golf or utility shifts.
• At 2000 W bursts or when towing a trailer uphill, expect shorter runtimes of around 2–2.5 hours, but the pack will support these high demands thanks to its high discharge capability.

These are estimates; actual performance depends on rider weight, terrain, speed, accessory loads, and temperature. You’ll want to record your typical current draw over a few rounds to refine the estimate for your specific cart.

Charging time and tips

The included 18 A charger typically brings the battery from empty to full in about 5.5 hours, which is convenient for overnight or mid-day top-ups. If you use partial charging (charging more frequently to 80–90%), you’ll reduce stress on the cells and maintain battery longevity.

For storage, charge to around 80% and perform one deep-discharge/charge cycle if the pack will be idle for a long time; that helps recalibrate state-of-charge readings. Avoid leaving the pack at 0% for prolonged periods and try to maintain moderate charge levels during long-term storage.

Maintenance and care

You’ll find LiFePO4 requires much less routine maintenance than lead-acid batteries because there’s no watering and the chemistry is more forgiving. Check mounting hardware, terminals, and monitor readings periodically to ensure everything remains secure and operating within normal parameters.

Keep the battery clean, dry, and free from corrosive substances, and avoid extended exposure to high heat. Those small practices will go a long way toward preserving cycle life and preventing premature failures.

Troubleshooting common issues

If the monitor shows unusual voltage or SOC readings, first confirm all connections are tight and polarity is correct. If the display reports temperature warnings or BMS errors, let the battery rest and cool down, then consult the manual or contact Elefast support.

For charging problems, verify the charger and AC outlet are functioning and that the charger is the correct LiFePO4 type. The app and touchscreen often log faults that you can share with tech support for faster diagnosis.
