This battery is built to replace traditional lead-acid packs in golf carts and similar vehicles, offering higher cycle life, lower weight, and built-in smart features that help you manage charging and performance.

Key specifications

Below you’ll find the main specs summarized so you can quickly see whether this battery meets your needs. These figures matter because they directly affect run time, charging behavior, and installation constraints.

Design and build quality

The LOSSIGY battery has a robust housing with an IP65 rating that protects it from dust and water jets, which is practical for outdoor use on golf courses or boats. The physical layout and terminals are designed so you can mount and wire the battery similarly to conventional batteries while enjoying the benefits of lithium technology.

Size and weight

At 20.47 × 10.59 × 8.66 inches and 83 pounds, you’ll notice how much lighter this pack is compared with equivalent lead-acid batteries. That 50% weight reduction means easier installation, better vehicle handling, and less stress on suspension and mounting points.

IP65 waterproof and casing

The IP65 rating indicates you won’t need to worry about splashes, rain, or dusty conditions when the battery is installed properly in a compartment. You should still avoid full immersion and protect connectors and charger ports from sustained wet conditions to preserve longevity.

Performance and capacity

Your golf cart’s range and power will improve because the LOSSIGY 48V100AH battery delivers 5.12 kWh of usable energy with high discharge capability. The LiFePO4 chemistry delivers stable voltage under load, so you’ll get more consistent performance compared to aging lead-acid packs.

Cycle life and longevity

This battery is rated for at least 4,000 cycles, which means if you use it daily, it will last several years with proper care—far exceeding the typical 300–500 cycles of lead-acid batteries. That extended cycle life should reduce the total cost of ownership over the battery’s lifespan, since you won’t be replacing packs as often.

Power and discharge (200A BMS, 1000A peak)

With a built-in 200A continuous BMS and 1000A peak current capability, the battery can handle high-start currents for electric motors and tolerate sporadic heavy loads without tripping. The combination of high continuous current and strong peak output is ideal for golf carts, trolling motors, and situations where initial torque demand is high.

Battery Management System (BMS)

The LOSSIGY pack includes an advanced BMS that performs multiple safety and maintenance functions automatically, which helps protect cells and maximize service life. The BMS manages cell balancing, over/under charge protection, overcurrent and short-circuit protection, and temperature regulation.

Protections and balancing

Thanks to internal balancing, the BMS equalizes cell voltages so you don’t end up with weak cells shortening the pack’s life; this is especially important when you run the battery hard or charge repeatedly. The BMS also prevents overcharging and deep discharging, which are common causes of premature battery failure.

Parallel connection limits

You can connect up to four LOSSIGY batteries in parallel to increase capacity while keeping voltage the same, but you must not connect them in series. If you need more range, combining up to four identical packs is the supported method, and mixing different states of charge or different-age batteries can create imbalance risks, so match batteries carefully.

Charger and charging speed

You’ll get a 58.4V 18A smart charger included, which is sized to fully charge the 100Ah pack in about 6 hours from empty under ideal conditions. The smart charger includes monitoring and termination features to avoid overcharging, and detachable cables make handling more convenient.

58.4V18A smart charger details

An 18A charger gives you faster turnaround between outings compared to slow trickle chargers that are common with lead-acid systems, and the 58.4V nominal charge voltage indicates the charger goes to a full LiFePO4 charge profile. The detachable input and output cables let you configure or replace connectors to match your setup or to charge remotely if needed.

Charging time and convenience

Expect roughly 6 hours for a full charge from near-empty when using the included charger; in practice, real-world times may vary slightly depending on temperature and battery state. If you have access to higher-current charging, check manufacturer guidance first, because the built-in BMS and charger ratings determine safe maximum currents.

Connectivity and monitoring

You can keep tabs on the battery’s status using Bluetooth on your smartphone and with the included LCD monitor that mounts in your cart for real-time readings while driving. Having both wireless and on-device displays gives you redundancy and the convenience of remote monitoring.

Bluetooth app monitoring

Once you pair your phone with the built-in Bluetooth chip, you’ll see cell voltages, state of charge, temperature, and other metrics through the app, which helps you make informed decisions about when to charge or how hard you can push your cart. Remote monitoring is especially useful when you have multiple batteries in parallel, because you can verify each pack’s behavior without opening the battery compartment.

LCD battery monitor

The included 9-in-1 LCD monitor displays essential parameters like voltage, current, and remaining capacity directly on the cart dash, providing a convenient readout while you’re driving. Having an on-dash display reduces surprises by alerting you to low battery early so you can avoid being stranded on the course.

Installation and compatibility

Installing the LOSSIGY battery is straightforward if you follow the instructions and ensure proper mounting and ventilation; you’ll appreciate the reduced weight during installation compared to lead-acid alternatives. Be mindful of terminal polarity and follow the manufacturer’s wiring recommendations to avoid damaging the BMS or voiding the warranty.

For golf carts and trolling motors

This battery is tailored for golf carts and trolling motors, and you’ll typically find it drops into existing compartments designed for 48V bank replacements, though you should confirm terminal placement and physical dimensions before buying. Its high peak current makes it a solid fit for vehicles with frequent starts and stops or for accessories that place additional load on the electrical system.

Wiring and replacement tips

When replacing a lead-acid pack, label wires and take photos to help you reconnect properly, and use appropriately sized cables and connectors to handle the 200A continuous rating safely. If you plan to parallel multiple packs, ensure they’re the same model, at similar states of charge, and that all connections are tight and corrosion-free to maintain balance and safety.

Weight and handling advantages

Because the LOSSIGY pack is about 50% lighter than equivalent lead-acid batteries, you’ll notice easier lifting, reduced strain on your vehicle, and potentially improved weight distribution. That lighter weight can also improve acceleration and reduce wear on suspension components over time.

Safety considerations

Although LiFePO4 chemistry is among the safest lithium variants, you still need to respect safe handling practices, avoid short circuits, and prevent crushing or puncture of the battery case. Don’t attempt to open or repair the battery yourself; contact LOSSIGY support for service and follow local regulations for battery disposal when the pack reaches end-of-life.

Maintenance and care

You don’t need the frequent watering and equalization cycles that lead-acid batteries demand, which saves time and reduces maintenance hassle. Still, you should keep terminals clean, verify cable connections periodically, and store the battery at moderate state of charge (around 50–60%) if you won’t use it for extended periods.

Troubleshooting common issues

If the battery doesn’t charge, first verify charger connections, fuses, and that the charger is powered; the detachable cables and visible indicators usually make diagnostics easier. For unexpected BMS trips or abnormal readings, check temperature and voltage, then contact support—do not repeatedly attempt to restart a tripped pack without diagnosing the cause.

Comparison with lead-acid and competitors

Compared to lead-acid batteries, the LOSSIGY 48V100AH gives you far more usable capacity (you won’t need to limit discharge as much), much longer cycle life, and a big weight reduction. Against other LiFePO4 offerings, LOSSIGY competes on cycle life, included charger quality, Bluetooth monitoring, and the convenience of an LCD monitor.
