You’re looking at a complete lithium conversion kit designed specifically for 48V golf carts and similar vehicles. This product bundles a 48V 100Ah LiFePO4 battery, a 58.4V 18A charger, and a smart 200A BMS that you can monitor via mobile app, aiming to give you more range, fewer headaches, and much less weight to deal with.

What’s included in the kit

The kit includes the 48V 100Ah LiFePO4 battery, the 58.4V 18A charger, and the smart 200A BMS with Bluetooth monitoring. You’ll also get the necessary cabling and mounting-friendly design for one-step installation in most 48V systems.

Key specifications at a glance

Here’s a concise table to help you quickly compare the main specs and features so you can see the highlights at a glance.

Performance

You’ll notice immediate differences in responsiveness, acceleration, and sustained hill-climbing performance when you switch to this LiFePO4 system. The 200A continuous discharge rating and 500A peak allow the battery to handle demanding loads that would strain older, heavier lead-acid setups.

Range and real-world runtime

On a single 48V 100Ah pack you can realistically expect 40–60 miles depending on load, terrain, speed, and how aggressively you drive. If you need extended range for tournaments or long outings, stacking up to four units can bring you close to 200 miles, which covers most full-day itineraries without range anxiety.

Acceleration and slope handling

Because LiFePO4 chemistry sustains higher discharge rates with less voltage sag, you’ll get stronger throttle response and more consistent torque on inclines. The continuous 200A output and 500A peak make climbing 20° slopes feel smoother and more reliable compared to older lead-acid setups.

Charging speed and charger behavior

The included 58.4V 18A charger will bring the pack to full in about 5.5 hours from a typical depth of discharge, which is far faster than many lead-acid chargers. The charger supports 0V recovery, so batteries that were deeply discharged have a better chance of being revived during charging.

Thermal and low-temperature performance

This pack includes low-temp protection in the BMS, which prevents charging below a safe cell temperature to protect cell health. You will still want to avoid extreme cold while charging, but the system gives you a safer margin than many non-protected lithium packs.

Battery Management System (BMS) and Smart Features

You get more than basic protection; the integrated 200A smart BMS offers several layers of monitoring and safety to protect both the battery and your vehicle. Bluetooth and the mobile app provide real-time data so you can manage performance proactively.

6-in-1 safety protections

The BMS monitors and controls overcharge, over-discharge, short-circuit, overcurrent, high-temp, and low-temp cut-off conditions. These protections work together to reduce risk, extend cell life, and prevent damage from common abuse or failure modes.

Mobile app monitoring and controls

By pairing the battery with the mobile app, you can view SOC (state of charge), per-cell voltages, pack health, and fault history. That visibility helps you make smarter charging and usage choices and simplifies troubleshooting when something looks off.

Design and build quality

The pack is engineered to be compact and light, using 16 Grade-A LiFePO4 cells fixed securely to resist vibration, shock, and the typical stresses of cart usage. The enclosure and terminal design are intended to fit existing battery bays and mounting points for many 48V carts.

Weight and footprint advantages

Compared with an equivalent lead-acid pack, this LiFePO4 pack is about 60% lighter and uses roughly 43% less cubic space. That means you’ll free up storage space, reduce vehicle weight, and improve handling and efficiency on the course.

Durability and cell mounting

Grade-A cell fixing and a shielded BMS arrangement help maintain cell alignment and wiring integrity over years of use. That attention to internal mechanical stability reduces risk of cell movement and stresses that can shorten battery life.

Compatibility and installation

This pack is designed to be a universal fit for most 48V golf cart setups and supports Club Car, EZGO, Yamaha, and similar platforms. The manufacturer emphasizes a one-step installation that avoids complicated rewiring, which should simplify your conversion process.

How to check compatibility with your cart

You should confirm your cart’s nominal voltage, terminal layout, and available physical space before buying to ensure a trouble-free installation. If you plan to stack packs, verify that the additional weight and mounting arrangement are safe for your vehicle and that your controller can handle the combined output.

Installation steps overview

Installation is straightforward but do require basic mechanical and electrical safety procedures. You’ll disconnect and remove the old batteries, position the LiFePO4 pack into the bay, secure it, connect the main leads, and plug in the charger to validate the pack and BMS operation.

Charging habits and battery care

Adopting a few simple charging and storage habits will keep the pack healthy for years and maximize the promised cycle life. Because LiFePO4 handles partial states of charge much better than lead-acid, you’ll enjoy more flexibility in when and how often you charge.

Recommended charging routine

Charge after each day of moderate to heavy use, or at least every few days if your cart sits unused to keep cells balanced. The relatively low self-discharge (about 3% per month) means you can store the pack for longer periods without significant capacity loss, but keeping it topped up is still best practice.

Storage and long-term maintenance

Store at moderate temperatures and avoid leaving the pack at full charge for extended periods in hot conditions to preserve cell life. If you’re storing the cart for months, aim for a storage SOC around 50–60% and periodic top-ups every few months.

Advantages over lead-acid batteries

Switching to this LiFePO4 system gives you immediate improvements in weight, cycle life, maintenance, and usable capacity. You’ll also reduce long-term costs because the chemistry lasts far longer and doesn’t require the frequent replacement or watering schedules that lead-acid batteries do.

Lifecycle cost and replacement frequency

With an estimated 15,000 cycles, the pack can last many years longer than lead-acid systems, which dramatically lowers lifecycle cost despite a higher upfront investment. You’ll avoid the recurring costs of replacing multiple lead-acid batteries every few years, and you’ll save time by removing regular maintenance tasks.

Usable capacity and efficiency

LiFePO4 provides more usable capacity because you can safely draw deeper without harming cell life, and the voltage stays steadier under load. This efficiency means you effectively get more usable miles per charge compared with lead-acid systems of equivalent nominal capacity.

Safety considerations

The built-in BMS and Grade-A cells provide a solid safety baseline, but you must still follow safe handling, charging, and installation procedures. Lithium batteries are robust when used correctly, but like any energy source they can be hazardous if abused or improperly installed.

Handling, mounting, and fusing

Secure mounting, correct torque on terminals, and using the recommended fuses or circuit protection are essential steps for safe operation. Follow manufacturer guidance on cabling and fuse sizing to ensure that peak current events don’t create unsafe conditions.

Temperature and charging precautions

Don’t attempt to charge the pack in extreme cold without first warming the cells within the safe temperature range, as the low-temp cut-off prevents charging and may lead to operational issues if ignored. Always place the charger on a stable, ventilated surface and use the supplied charger to ensure compatibility with the battery’s chemistry and BMS.
