Key specifications

Here’s a tidy breakdown of the most important specs so you can see the numbers at a glance. The following table highlights the core technical details that matter when you’re evaluating fit, power, and compatibility.

This table helps you compare the battery to other options quickly, and verifies that you’re getting both power and accessories in a single package.

Build quality and design

You’ll notice the battery arrives in a sheet metal shell that’s made to resist rust, water, and corrosion. That metal enclosure gives the pack durability and protection against the kind of abuse a golf cart battery is likely to see on wet, dusty, or salty courses.

The design also integrates user-friendly elements: the LCD touch screen for immediate readout, Bluetooth-enabled BMS for remote diagnostics, and the retention straps for secure mounting. Everything feels aimed at making a rugged hardware platform accessible to owners who want minimal fuss after installation.

Physical protection and mounting

The sturdy sheet metal case helps protect internal cells from impact and environmental exposure, while the included straps make it easier to secure the pack in the battery bay. You’ll appreciate not having to source a separate mounting solution, especially if your cart’s battery compartment has tight or unusual mounting points.

Straps are long enough for many common golf cart layouts and can be routed and tightened to hold the battery firmly under normal driving conditions. If you plan heavy off-road use or extreme vibration, consider additional padding or a custom tray for the highest level of security.

Performance and power

This battery delivers 51.2V nominal and 100Ah of capacity, which gives you roughly 5,120 Wh of usable energy at nominal voltage. If your golf cart motor and controller can draw the allowed continuous current, you can access high power bursts for acceleration and climbs.

With a BMS rated to handle continuous discharge currents up to 200A and the cell arrangement built for higher-rate discharging, the pack can support substantial loads without excessive voltage sag. The Max.Power claim of 10.24 kW reflects the battery’s ability to supply high instantaneous power for short periods when you need it.

Continuous discharge and short bursts

You’re covered for heavy loads thanks to the 200A continuous rating—ideal for steep hills, heavy passengers, or towing small loads. The cells themselves are A-level, supporting up to 2C in some configurations for brief bursts, which helps maintain performance under sudden load increases.

If your usage pattern includes repeated maximum draws or continuous high-power use, watch battery temperature and duty cycle. The BMS will protect against overheating, but continuous heavy loads will reduce your net runtime compared to gentle cruising.

Real-world runtime expectations

Estimating runtime depends on load. For example, if your cart draws an average of 800W during typical recreational use, your 5.12 kWh pack gives roughly 6–6.5 hours of operation under ideal conditions. If you’re pulling heavier loads and average 2,000W, expect about 2–2.5 hours.

Keep in mind those are approximate figures: actual runtime varies with vehicle efficiency, terrain, weight carried, speed, and auxiliary loads like lights or audio. You can use the Bluetooth monitoring and the LCD screen to track consumption and refine your expectations.

BMS and Bluetooth monitoring

The built-in 200A BMS (Battery Management System) manages cell balancing and protective cutoffs while providing Bluetooth connectivity for app-based monitoring. You’ll be able to check state of charge (SoC), cell voltages, current, temperature, and fault messages on your phone in real time.

The BMS also includes low-temperature cut-off technology to prevent charging under unsafe cold conditions, plus the usual protections for overcharge, over-discharge, overcurrent, short circuit, and overheating. If anything abnormal happens, the BMS will isolate the battery and show alerts in the app and possibly on the local LCD.

What you can monitor via Bluetooth

You’ll get access to data like SoC, voltage per series string, charging/discharging current, and temperature readings inside the pack. This means you won’t have to rely only on guesswork to understand how much energy you’ve used or how healthy the pack is.

Having Bluetooth monitoring helps with early detection of issues (for instance, an imbalanced string) so you can address them before they lead to bigger problems. The manufacturer instructs you to download the app as per the manual to pair and view all parameters.

Charging: 20A fast charger and charging behavior

The included 58.4V 20A fast charger is designed to quickly replenish the 51.2V pack. In ideal conditions, charging from near-depleted to full at 20A for a 100Ah pack takes roughly 5–6 hours because LiFePO4 charging typically uses a constant-current/constant-voltage profile and tapers at the end.

Because LiFePO4 chemistry accepts higher charge currents and has lower internal resistance than lead-acid, you’ll notice faster recharge cycles and less heat generation during charging. The BMS handles charging cutoffs and cell balancing, so you get safe, efficient fast charging without babysitting the pack.

Charging tips and behavior

Charge in a well-ventilated, dry area and avoid extreme cold or hot ambient temperatures for fastest, most reliable charging. The BMS’s low-temperature cut-off prevents charging if temperatures are too low, which protects the cells and preserves cycle life.

If you often top off the battery between uses, that’s fine—LiFePO4 tolerates partial charges very well and actually benefits from more frequent shallow cycles compared to lead-acid chemistry.

Installation and setup

Installing the pack is straightforward if your cart is already configured for a 48V system. You’ll remove the old lead-acid bank, confirm polarity and cable sizes, secure the battery with the provided straps, and plug in the charger and display as instructed in the manual.

If your cart uses different terminal locations or has custom wiring, you may need adaptors, longer cables, or a minor reconfiguration. Ensure connectors are clean and tight, and double-check polarity before applying power to avoid damage. If you’re not comfortable with electrical work, a professional install is a safe choice.

Step-by-step quick install checklist

1. Disconnect the cart and remove the old batteries, noting cable routing.
2. Inspect the battery compartment for corrosion or debris and clean as needed.
3. Position the new battery, route the retention straps and tighten securely.
4. Make electrical connections, ensuring correct polarity and tight terminals.
5. Install the LCD touch screen and pair the Bluetooth app per manual instructions.
6. Plug in the included 20A charger and perform the first full charge before use.

Following a routine checklist keeps installation safe and reduces the risk of accidental damage or reversed connections.

Compatibility: which carts and motors will work

You’ll want to confirm your cart is built for or can be converted to a 48V system. Most modern 48V golf carts and many conversion kits are compatible with a 51.2V nominal lithium pack. The battery is also well-suited for trolling motors and similar 48V electric applications that require steady high currents.

If your cart is currently 36V or some other configuration, this battery won’t be a direct drop-in. You can convert systems, but conversions require changes to controllers, chargers, and sometimes the motor. Always verify controller voltage ratings and fuse sizes to ensure safe operation.

Electrical and physical fit considerations

You’ll need to confirm the battery’s dimensions and terminal placement match your battery bay or allow for a secure mounting solution. Make sure your cart’s wiring gauge and fuse settings match the higher continuous discharge capability—200A is significant, and undersized wiring or incorrect fusing creates safety hazards.

If you have a factory controller limited to lower currents, you may not utilize the full power of the pack, but you’ll still benefit from longer runtime and lifespan.

Lifespan and cycle life

The manufacturer states 6000+ deep cycles, which is a major selling point compared to typical lead-acid batteries that often reach a few hundred cycles at best. In practical terms, this means the battery can last many years under normal usage patterns before capacity drops noticeably.

You’ll find that LiFePO4 chemistry exhibits a slow, linear capacity fade and low self-discharge, so the battery retains charge when the cart sits idle for extended periods. With correct charging habits and temperature management, you can realistically expect several years of trouble-free service.

How cycle life translates to ownership cost

Higher cycle life reduces the frequency of replacement and lowers long-term ownership cost. Even if the initial outlay is higher than AGM, fewer replacements and reduced maintenance (no watering or equalizing charges) generally mean a lower total cost of ownership over the battery’s lifetime.

Keeping the pack within recommended temperature ranges and avoiding deep discharges below recommended cutoffs will maximize its usable life.

Safety features and protections

You’ll benefit from multiple safety layers: the 200A BMS protects against overcharge, over-discharge, overcurrent, short circuits, and overheating, while low-temperature cut-off prevents unsafe charging in cold conditions. The robust metal shell also adds passive safety by protecting cells from physical damage.

LiFePO4 chemistry itself is more thermally stable than many other lithium types, which reduces the risk of thermal runaway. Nonetheless, treat the pack like any high-energy electrical device: avoid punctures, extreme impacts, and direct exposure to fire or conductive contaminants.

What to do if a protection event occurs

If the BMS isolates the pack due to a fault or protective cutoff, inspect for obvious causes: loose or corroded terminals, abnormal charging behavior, or high ambient temperatures. Use the Bluetooth app to read error codes and consult the manual for specific troubleshooting steps, or contact manufacturer support for guidance.

Maintenance and storage tips

You don’t need to water or equalize this battery like you do with flooded lead-acid. However, you should keep terminals clean and tight, maintain the battery at moderate temperatures, and store it at a partial state of charge if you won’t use it for long periods.

Periodic charging every few months is beneficial to keep the battery in healthy condition and prevent it from remaining at very low SoC. If you store in cold climates, avoid storing below the BMS’s low-temperature charging cutoff—charging in freezing temperatures can damage the cells.

Seasonal storage recommendations

For long-term storage, aim for 40–70% state of charge, keep the pack in a cool, dry place (above freezing), and check charge every 3–6 months. If you plan heavy seasonal usage and long off-seasons, those periodic top-ups will preserve capacity and ensure a healthy start when you return.

Real-world testing and user experience

In practical usage many owners report noticeable advantages: longer range per charge compared to equivalent Ah of lead-acid, quicker acceleration, lighter weight, and the convenience of the fast charger and Bluetooth monitoring. The included touchscreen makes it easy to verify SoC without opening compartments.

Users who switch from lead-acid often highlight the low maintenance and the ability to run more trips per day without battery sag. You’ll also appreciate cold-start reliability and consistent voltage under load, providing a more predictable driving experience.

Common real-world numbers

Typical carts configured for leisure cruising can expect several additional miles or more of range compared to older lead-acid setups, depending on motor efficiency and load. The high continuous discharge rating also means you’re less likely to experience severe voltage sag during hill climbs or when carrying heavier loads.

Troubleshooting common issues

If the battery doesn’t charge, check the charger connections, the charger itself, and the BMS Bluetooth status. Look for BMS fault codes in the app and confirm the charger is correctly configured for LiFePO4 chemistry and the correct voltage.

If you see unexpected voltage sag or rapid SoC drops, inspect terminal connections, check for parasitic loads when the cart is off, and confirm ambient temperature. Contact support if issues persist, and use the warranty if the pack shows clear early degradation or manufacturing defects.

Quick fixes for typical minor problems

• Loose terminals: tighten and clean contacts.
• Charger not starting: verify AC input and charger model, check the AC port plug included in the kit.
• App pairing issues: ensure Bluetooth on your phone is active and follow the manual’s pairing steps.

Comparing to AGM and other lithium options

Compared to AGM lead-acid batteries, you’ll get lighter weight, far more cycles (6000+ vs. a few hundred), better usable capacity (no need to oversize for depth of discharge), and lower maintenance requirements. The initial cost will be higher, but the long-term economics usually favor LiFePO4 for regular use.

Compared to other lithium chemistries, LiFePO4 is safer and more stable, though slightly heavier than some high-energy lithium variants. For vehicle applications like golf carts, LiFePO4 often hits the best balance of safety, lifespan, and cost-effectiveness.

Total cost of ownership perspective

When you add fewer replacements, no watering, reduced downtime, and better performance, the investment pays back over time—especially if you use the cart frequently or commercially. If your usage is very light, the payback period will be longer, but you still get convenience and improved reliability.

Pros and cons

You’ll appreciate the long cycle life, strong continuous current, included fast charger, Bluetooth monitoring, and robust build quality. These features combine to make the battery a compelling replacement for older lead-acid systems and a versatile pack for many 48V uses.

On the downside, the upfront cost is higher than lead-acid options and you’ll need to ensure physical and electrical compatibility with your specific cart model. If you rely on legacy 36V systems, this pack won’t be a direct swap without a conversion.
