Key specifications

This section gives you a concise technical snapshot so you can quickly see whether the battery fits your needs. Below is a compact table to make the main specs easy to scan and compare.

What this battery actually is

You’ll get a plug-and-play 48V LiFePO4 battery pack designed as a direct upgrade for many 48V applications. The manufacturer used 16 A-grade EVE LiFePO4 cells and integrated a high-current BMS for protection and performance. The pack is enclosed in a cold-rolled steel case, which is far more robust than typical plastic cases and adds fire resistance.

Battery chemistry and cell construction

You should know the battery uses LiFePO4 chemistry (lithium iron phosphate). LiFePO4 is known for excellent thermal and chemical stability, lower risk of thermal runaway, and long cycle life compared with many other lithium chemistries. The pack uses 16 UL-certified 2C cells from EVE, which helps ensure consistent performance and balanced capacity across the pack.

Capacity and range expectations

This 48V 100Ah battery provides around 5.12 kWh of usable energy if you accept its claim of 100% usable capacity. In practical terms, that means:

• If you run a 3 kW electric motor on a golf cart, you can expect roughly 40 miles under favorable conditions.
• Typical cruising ranges are estimated at 40–56 miles, depending on vehicle weight, terrain, driving style, and accessories like lights or heaters you might use.

You should treat range estimates as approximations because hills, stop-and-go operation, heavy loads, and ambient temperature will affect real-world results.

Power delivery, BMS, and performance limits

You’ll appreciate that the pack supports very high discharge currents: 1000A peaks for short bursts and 300–600A for sustained durations. That’s useful for strong acceleration and climbing steeper hills. The built-in 200A BMS protects the battery from common problems like overcharge, over-discharge, overload, short circuits, and temperature-related issues. It also supports safer use under-seat due to strong thermal and chemical stability.

Build quality, casing, and physical durability

The casing is cold-rolled steel with a black baked enamel finish, which resists rust and oxidation better than plastics or thin steel. The case also incorporates a pressure relief valve that vents if internal pressure builds, reducing the risk of case rupture. You’ll also find a one-touch power switch for easy cut-off during storage or maintenance. The IP65 rating adds protection against dust and low-pressure water jets, making the battery suitable for outdoor equipment and damp conditions.

Charging: charger, times, and temperature guidance

You get a 58.4V 18A LiFePO4-specific charger which should recharge the battery in about 5 hours from empty to full under ideal conditions. Charging below 32°F (0°C) is not recommended because low temperatures can reduce available capacity and harm the pack. If you live in a cold climate, you should plan to protect the battery or charge only when temperatures are above freezing. The BMS will also help protect the battery during charge cycles.

Monitoring options: Bluetooth app and touch LCD

You can monitor the battery either through the included Bluetooth LCD touch display or via the Bluetooth 5.0 mobile app. Both show state of charge (SOC), voltage, current, temperature, and capacity. Note that the Bluetooth connection supports only one device at a time—so you must disconnect the mobile app to use the LCD screen and vice versa. The included LCD is relatively large and makes it easier to read real-time data when you’re near the vehicle.

Real-world performance and use cases

If you use this battery on a typical golf cart powered by a 3 kW motor, you’ll likely be able to complete multiple rounds (4–9 rounds of 18 holes) on a single charge depending on terrain and load. The battery’s high peak current capabilities mean acceleration is responsive and the pack can climb slopes of about 20 degrees without dramatic voltage sag in most cases. You’ll also find it suitable for other 48V systems like lawn mowers, small RV systems, trolling motors, and small off-grid setups.

Cycle life and long-term value

One of the biggest selling points is the claimed 10,000+ deep cycles at 80% DOD. If that holds in real life, your cost per cycle will be far lower than AGMs, which typically manage 300–600 cycles. That translates into years of heavy use—if you charge and discharge daily, you could still have a viable battery for many years. You’ll likely save on maintenance, replacement costs, and weight penalties compared to traditional lead-acid banks.

Safety features and thermal behavior

Safety is core to this pack: LiFePO4 chemistry is inherently stable, the steel casing provides thermal and mechanical protection, and there’s a built-in pressure relief valve for extreme conditions. The BMS watches temperature and isolates the battery during unsafe conditions. You should still respect basic safety procedures—avoid physical damage to the pack, ensure proper mounting, and keep vents clear.

Pros

You’ll gain several clear advantages if you choose this battery:

• Long cycle life that significantly reduces replacement frequency and cost per cycle.
• High discharge rates and peak output suitable for demanding loads and hills.
• Sturdy steel casing with improved fire resistance and corrosion protection.
• Plug-and-play simplicity with included charger and monitoring hardware.
• IP65 rating and broad operating temperature range for versatile outdoor use.
• Good monitoring options via app and a dedicated LCD touch screen.

Cons

You should also be aware of potential downsides and trade-offs:

• The pack is heavier and larger than individual small-format cells—so verify fitment before purchase.
• Bluetooth connection can only be used by one device at a time, which may be inconvenient if you want simultaneous display and phone monitoring.
• Charging below 32°F is discouraged; you may need a heated enclosure or to bring the battery indoors in very cold climates.
• The manufacturer advises against series connections; you can only parallel up to eight packs if you need more capacity. This limits very high-voltage system expansions.

Each con is manageable with planning: measure your battery bay, plan for cold-weather charging, and configure monitoring preferences to avoid connection conflicts.

Installation and quick-start guide

This battery kit is designed for one-time installation and plug-and-play operation. You’ll usually swap it in where an old 48V battery bank sat, but you should still follow a few steps to ensure safe and effective installation.

Pre-install checks

Before you start, inspect the battery bay for corrosion, loose wiring, and compatibility with the battery’s physical dimensions and mounting points. Confirm that your vehicle’s motor controller and electrical system accept a 48V nominal pack and that you won’t exceed any amperage limitations on fuses or wiring.

Installation steps

1. Turn off your vehicle and remove the old battery bank safely, following manufacturer instructions for hazardous waste and recycling.
2. Place the new LiFePO4 pack in the battery compartment, securing it using the existing mounts or straps. Make sure the one-touch power switch is accessible.
3. Connect the main positive and negative terminals securely with appropriate high-gauge cables. Ensure polarity is correct—reverse polarity will damage electronics.
4. Connect any communication lines for the LCD if required by your vehicle.
5. Power up the battery and check the LCD for initial readings and status. If you use the app, pair the mobile device following the user manual.

First charge and calibration

You should fully charge the pack after installation using the supplied 58.4V 18A charger. Allow the battery to complete its charge cycle and stabilize. The BMS and SOC algorithms may require a few cycles to present the most accurate state-of-charge readings, so plan a couple of charge/discharge cycles for best results.

Parallel use and expansion rules

If you want to increase capacity, the manufacturer allows parallel connections of multiple packs—up to eight units (max 800Ah). You must never connect packs in series or mix different aged packs and chemistries. When paralleling, use identical packs, identical state-of-charge when connecting, and short, equal-length cables to balance currents.

Maintenance and storage recommendations

You’ll enjoy relatively low maintenance compared to lead-acid, but there are still best practices to extend the life of your battery:

• Keep terminals clean and tight; periodically inspect the connectors for corrosion or wear.
• Store the battery at a partial state of charge (around 50–60%) if you won’t use it for extended periods. That reduces stress relative to storage at 100% or near 0%.
• Avoid frequent deep discharges below the BMS cutoff—while the cells support deep cycles, staying within reasonable depth increases cycle life.
• Keep the battery in a dry, ventilated environment and protect it from extreme temperatures. Charging above 32°F is recommended to avoid permanent capacity degradation.
• Turn off the LCD screen when the battery is not in use to prevent inaccurate SOC readings and unnecessary drain.

Troubleshooting common issues

You’ll occasionally hit minor issues—here are quick fixes for the most common ones:

• App won’t connect to LCD: Ensure the mobile app is disconnected before trying to use the LCD. Bluetooth supports only one connection at a time.
• Charger doesn’t start: Check main fuse and the one-touch power switch. Verify charger output and proper cable connections.
• Reduced range or unexpected voltage sag: Check for heavy loads, cold temperatures, and long runs of thin cable that add resistance. Ensure the battery is charged and the BMS has not entered a protective mode.
• Over-temperature warnings: Check ventilation and ambient temperature. Avoid blocking airflow and consider relocating the pack if installed in a tight, heat-trapping space.

If problems persist, the manufacturer offers 5 years of after-sales service and technical support with tutorial videos and responsive support hours.

Safety and regulatory considerations

You should always handle batteries carefully. This pack reduces risk through LiFePO4 chemistry and a steel enclosure, but follow safe practices: avoid short circuits, don’t puncture the case, and don’t charge in temperatures below recommended levels. Also adhere to local disposal and recycling rules for lithium batteries. The pack includes UL-certified cells, which helps with compliance and insurance considerations in many regions.

Comparison: LiFePO4 vs AGM for your golf cart

You want the easiest way to see differences, so here’s a short comparison:

• Cycle life: LiFePO4 >> AGM (10,000 cycles vs 300–600 cycles). You’ll replace AGMs far more frequently.
• Weight and energy density: LiFePO4 is lighter and stores more energy per kg than AGM, improving vehicle range and payload.
• Maintenance: LiFePO4 is maintenance-free; AGM needs watering and regular checks in certain setups.
• Efficiency: LiFePO4 charges and discharges more efficiently with less energy loss.
• Cost: Upfront cost is higher for LiFePO4, but total cost of ownership becomes lower over time because of longevity and performance.

If you want fewer replacements and better performance, this LiFePO4 solution is a strong choice.

Who this battery is best for

You’ll find this kit especially well-suited if you:

• Want to convert your golf cart from lead-acid to lithium with minimal wiring hassle.
• Operate in damp or dust-prone environments and need an IP65-rated pack.
• Use your cart for frequent rounds and want a long-lived battery to reduce replacement cycles.
• Have a small fleet of carts or vehicles and want to lower maintenance and downtime.
• Use other 48V systems like lawn mowers, trolling motors, or small off-grid systems and want a robust, stackable battery.

If you only use your cart infrequently and upfront cost is your only concern, you should still evaluate total cost of ownership to see if LiFePO4 makes sense.

Practical scenarios and range examples

Here are a few real-world scenarios to help you estimate what you can expect.

• Casual golf player on flat terrain: If you’re driving conservatively on mostly flat courses, you should get closer to the 50–56 mile end of the range estimate, likely allowing 6–9 rounds.
• Hilly or heavy-load operation: If the course or terrain has frequent slopes and you carry heavier loads, expect range closer to 40 miles per charge. The battery’s high current capability will help maintain performance, but energy use will increase.
• Utility or residential use (mower, UTV): For lawn mowers and work vehicles, runtime depends heavily on motor power and accessories. You’ll often find this pack sufficient for morning or afternoon jobs without recharging mid-day.

Warranty, support, and after-sales

You get a 5-year after-sales service commitment with the product, and the manufacturer offers technical support, video installation guides, and reasonably fast responses during their advertised hours. If you run into installation or battery behavior questions, you’ll likely find helpful documentation or direct support.

Frequently asked questions (FAQ)

You’ll likely want answers to these common points:

• Can you connect multiple batteries in series? No. The manufacturer explicitly warns against series connections as they can cause irreversible damage. Parallel connection up to 8 packs is allowed.
• Can the LCD and mobile app run at the same time? No. Bluetooth allows only one connection at a time; you must disconnect the mobile app to use the LCD and vice versa.
