Key Specifications

You’ll want the technical details at your fingertips when comparing batteries or planning installation. Here’s a concise breakdown of the most relevant specs.

Build and Materials

You’ll immediately notice the tougher build compared with many consumer batteries. The metal casing is designed to handle abuse and dissipate heat better than plastic housings.

The metal shell enhances impact resistance and improves heat dissipation, which helps stabilize the top-mounted cylindrical cells. That combination reduces the chance of the BMS cutting power due to temperature or imbalance, and it supports a long lifecycle.

Cylindrical Cells and Thermal Management

You’ll benefit from a design that keeps cells cooler under load. Cylindrical cells typically have better thermal pathways than some prismatic options.

Because the case is engineered with heat dissipation in mind, the cells operate at more stable temperatures, which contributes directly to the declared 15,000+ cycle life and improved consistent performance on long rides.

Forced Power Switch and Serviceability

You’ll appreciate the integrated forced power switch for quick restarts. Unexpected lockouts or errors can often be resolved instantly with a one-touch restart rather than complicated resets.

This feature is handy if you’re out on the course and need a fast recovery without tools or deep troubleshooting.

Performance and Range

You want reliable range and torque so your cart doesn’t leave you stranded. This battery promises a substantial range and strong output for demanding routes.

Rated at 5120Wh with continuous discharge at 200A and a 500A burst, you can expect strong acceleration and the ability to carry multiple passengers uphill. The product claims a 50+ mile range on a single charge, although actual range will depend on cart efficiency, terrain, load, and driving habits.

Practical Range Considerations

Your real-world range will vary. Flat courses with light loads will approach the higher end of range estimates, while hilly or heavily-loaded use will reduce miles per charge.

When estimating range, consider average power consumption in watts. If your cart typically draws 800W-1,000W while moving, 5.12kWh could give you roughly 5–6 hours of runtime under steady draw, translating to long mileage on lower-speed courses.

Torque and Peak Power

You’ll notice the immediate torque thanks to the high continuous and peak currents. The 200A continuous discharge supports sustained power, while 500A bursts let the motor handle short intense loads like steep climbs or quick accelerations without BMS intervention.

This is especially useful when carrying multiple passengers or blasting up hills.

Battery Management System (BMS)

You’ll want a robust BMS to protect your investment. This battery includes a 200A BMS with multiple protections designed to keep your pack safe and extend its service life.

The 200A BMS provides protection against overcharge, over-discharge, overload, short circuit, and temperature extremes. The BMS is a core element that makes the pack suitable for demanding applications beyond golf carts, such as trolling motors, RVs, solar storage, and marine use.

Low-Temperature Protection

You’ll be glad it handles cold climates better than most lead-acid batteries. The built-in low-temperature cut-off prevents charging below 32°F (0°C), which protects the cells from lithium plating and potential damage.

Discharging remains possible down to -4°F (-20°C), so you can still run your cart on chilly days although you should avoid charging in freezing conditions.

Installation and Electrical Compatibility

You’ll find this battery significantly simplifies wiring compared to multiple 12V batteries. The single 48V package reduces the number of connections and the risk of wiring errors.

Make sure your cart controller and charger are compatible with a 48V LiFePO4 pack. Because the BMS supports high continuous currents, most modern 48V controllers will work fine, but confirm controller current limits and wiring safety first.

Monitoring: Bluetooth and LCD

You’ll like the dual monitoring options—an LCD on the battery and Bluetooth connectivity for remote monitoring. Both give you visibility into voltage, temperature, state of charge, and cell-level data.

The Bluetooth 5.0 connection pairs with the Humsienk app for real-time diagnostics and remote control of charging/discharging. The LCD offers instant local readouts when you’re inspecting the battery physically.

App and Remote Diagnostics

You’ll be able to pair quickly and view detailed cell/battery data through the app. Remote diagnostics can help you identify issues early and minimize downtime.

Using the app, you can check voltages, temperatures, and BMS alerts, which is useful when you want to confirm battery health without opening the cart compartment.

Charging

You’ll receive a 58.4V 15A charger tailored for this battery, giving you a complete recharge in roughly 7 hours from a fully depleting state if conditions are ideal.

The charger is built with an aluminum shell that’s shock-resistant and vibration-proof, and it includes protections for overcharge, over-discharge, and over-temperature. It supports 100V–240V input, so it’s usable worldwide with the correct plug adapter.

Charging in Cold Weather

You’ll need to be careful about charging in low temperatures. Charging is disabled below 32°F (0°C) to prevent cell damage, so plan warm storage or charging indoors if you’ll be using your cart in winter and need to charge between rounds.

If you must charge in chillier environments, consider a heated storage area or temperature-controlled garage to maintain battery longevity.

Size, Weight, and Installation Benefits

You’ll notice the weight and size savings immediately if you’re replacing four 12V lead-acid batteries. This pack is 62% lighter and 23% smaller than four 12V 100Ah lead-acid batteries.

Those reductions make installation easier and free up space for other components or luggage. Fewer battery boxes and simpler mounting mean faster swaps and less routine maintenance.

Mounting Tips

You’ll want to mount the battery in a place with good airflow for cooling, secure fasteners to limit vibration, and proper access to the forced power switch and LCD. Because it’s IP65 rated, protection from moisture and dust is robust, but avoid direct stream cleaning and prolonged submersion.
