Product overview

You’re looking at the Power Queen 48V 100Ah Lithium Golf Cart Battery, Group 8D LiFePO4 Battery with Bluetooth 5.0, Built-in 200A Smart BMS with Low-temp Protection for 5kW Motor Golf Carts Club Car DS E-Z-Go TXT. This battery is designed as a direct replacement for multiple flooded lead-acid batteries and aims to give you more range, less maintenance, and smarter monitoring. You’ll find it engineered to fit BCI Group 8D dimensions and to integrate smoothly into common 48V golf cart systems.

What this battery replaces and why it matters

This single 48V (51.2V) 100Ah battery replaces six 6V or multiple 8V flooded lead-acid batteries, reducing installation complexity and maintenance. For you, that means fewer connections to check, less weight in some setups, and a lot less time watering and balancing cells. The idea is one installation replaces the old multi-battery bank and gives you immediate benefits.

Who this is built for

This battery was created primarily for golf carts—Club Car, E-Z-Go, Yamaha and similar models—plus low-speed vehicles, UTVs, NEVs, and even electric outboard motors when arranged in parallel. If you want extended range, strong hill-climbing and a maintenance-free option, this unit is targeted at you. It’s also a strong fit if you want Bluetooth monitoring and a modern BMS for peace of mind.

Quick specifications

These quick specs give you a snapshot so you can check fit and capacity at a glance. You’ll be able to see what matters for physical fit, electrical compatibility, and expected performance.

These specs should help you judge fit and suitability quickly. Make sure to confirm physical dimensions and terminal type match your installation before purchase.

Battery performance

You’ll get strong real-world performance from this LiFePO4 pack compared to flooded lead-acid alternatives. The capacity and discharge profile are suited to higher-power motors and extended drives.

Range and usable capacity

With a usable capacity of roughly 5.12 kWh, you can expect about 40–47 miles on a single charge with a typical 5 kW golf cart motor under moderate conditions. Your actual range will vary with terrain, load, driving style, and accessory usage (lights, stereo, etc.). Because LiFePO4 chemistry supports a wider usable depth of discharge, you can use more of the battery’s rated capacity without harming longevity.

Power delivery and acceleration

You’ll notice sharper acceleration and better hill-climbing thanks to the 200A continuous discharge capability and the 1-second 1000A peak. That peak gives your motor short bursts of extra torque for steep climbs or quick maneuvers. If you often carry heavy loads or drive hilly courses, the improved discharge capability will matter to you.

Efficiency and self-discharge

This battery’s low self-discharge (≤2% monthly) means it stays ready for use longer than flooded lead-acid batteries. You won’t need to top it off as often if your cart sits unused for days or weeks. The high round-trip efficiency typical of LiFePO4 also lowers energy loss when charging and discharging, so more of what you charge is available to drive.

Build quality and design

The Power Queen battery is assembled with prismatic LiFePO4 cells and a robust enclosure designed for the rigors of outdoor vehicle use. You’ll find it both compact for the energy it stores and built for repeated cycles.

Physical dimensions and fit

Sized to BCI Group 8D dimensions (20.47 x 10.59 x 8.66 inches), this battery should fit many OEM battery compartments designed for that group. Even so, you’ll want to measure your compartment and check terminal location before installing. Proper fit reduces stress on cables and prevents rattling, which helps longevity.

Connectors, terminals, and mounting

Terminals and connector placement are designed to be compatible with common golf cart wiring patterns, but you should check polarity and terminal orientation carefully. The pack includes robust terminals suitable for the current this battery will handle, and the case vents heat effectively to keep temperatures balanced. Secure mounting is essential to prevent vibration damage—use factory hold-downs or equivalent brackets.

Built-in BMS and safety features

The integrated 200A smart Battery Management System (BMS) is an essential part of what makes this battery safer and more user-friendly than older battery types. You’ll get automatic protection and state monitoring that simplifies use.

200A Smart BMS capabilities

The BMS handles over-charge, over-discharge, over-current, short-circuit, and high/low temperature protection. It also offers self-recovery protection and a pre-charge function for easier compatibility with some controllers. For you, that reduces the chance of catastrophic failure and provides smoother compatibility with your cart’s electronics.

Low-temperature protection and charging behavior

The battery supports low-temp protection, which prevents charging below a certain cell temperature to avoid lithium plating and damage. This is important if you operate in colder climates or store the battery in an unheated space. The BMS will block charging when temperatures are unsafe and resume automatically when conditions recover, so you don’t have to babysit charging in cold weather.

Bluetooth 5.0 monitoring and the app

Bluetooth 5.0 lets you monitor SOC (state of charge), voltage, current, power, and remaining capacity via the Power Queen app. The app can also present low-battery reminders—e.g., SOC display color changing when below 20%—and enable remote discharge management or shutdown. You’ll appreciate the visibility into battery health and usage trends, especially if you manage multiple vehicles.

Compatibility and installation

You’ll want a clear checklist before you buy to ensure the battery will integrate smoothly with your cart and charging system. This section helps you confirm compatibility and gives tips for installation.

Golf cart and vehicle compatibility

This battery is designed for 48V systems found in many golf cart manufacturers (Club Car, E-Z-Go, Yamaha, etc.), plus LSVs, UTVs, NEVs, and certain marine or off-grid setups when used appropriately. Check your cart’s nominal system voltage and controller ratings—particularly continuous and peak current limits—before installing. If your controller or motor exceeds the BMS continuous rating or expects a different voltage, consult a technician.

Replacing 6V/8V flooded banks

Because one 48V 100Ah pack replaces multiple 6V or 8V flooded batteries, you’ll simplify wiring and balance issues. You’ll remove the old series/parallel ganged batteries and replace them with this single pack, but you must ensure the new terminal polarity and voltage match your cart’s wiring. If you’re switching from a 6V string, you’ll commonly remove six 6V batteries; in an 8V layout, confirm how many units were used and their configuration.

Installation steps and tips

1. Turn off the vehicle and isolate all power. Remove keys and place main disconnects where applicable.
2. Remove old batteries and clean terminal areas and tray. Inspect cables for corrosion and replace if necessary.
3. Verify the Power Queen battery dimensions fit in the compartment and that hold-downs secure it firmly.
4. Connect the main positive and negative leads, observing correct polarity. Use appropriately sized cables and torque terminals to manufacturer spec.
5. Power on the system and allow the BMS to complete any pre-charge or initialization steps. Use the app to confirm SOC and health.
6. Take a short test drive to verify motor response, controller behavior, and no fault codes.
   You should follow manufacturer guidance and consider professional help if you’re not comfortable with high-current electrical work.

Durability and lifecycle

If longevity and total cost of ownership matter to you, this LiFePO4 pack is engineered to reduce replacement frequency and maintenance costs compared to lead-acid alternatives. Expect a noticeable difference in lifecycle economics.

Cycle life and expected lifespan

The battery is rated for over 4000 cycles to its specified end-of-life criteria, with a projected useful lifespan of up to 10 years under normal usage. This cycle life is far superior to typical flooded lead-acid batteries and translates into fewer replacements. If you discharge to conservative depths of discharge and avoid extreme temperatures, you’ll get closer to the higher end of that lifespan.

Maintenance-free operation

You won’t need to water cells, perform regular equalization charging, or manage cell-specific balancing manually. The built-in BMS and the stable LiFePO4 chemistry remove much of the routine maintenance older battery chemistries require. That saves you time and reduces the risk of operator error damaging the battery.

Real-world use cases

You’ll find many practical scenarios where this battery shines, from heavy use on hilly courses to multi-day event coverage without recharging. Think beyond golf to other vehicles and energy needs.

Golf carts and low-speed vehicles

For golf carts with 5kW motors, this battery can deliver consistent power throughout rounds and often complete hours of use without recharging. You’ll appreciate more consistent voltage under load compared to lead-acid, which reduces dimming lights and slower top speed common toward the end of a charge in older systems.

Other applications (home backup, outboards, mowers)

Thanks to the robust BMS and parallelability for larger capacity, you can also use this battery for electric outboard motors, lawnmowers, home energy storage, and off-grid systems when the installation is designed correctly. You could parallel multiple units for higher capacity and redundancy, but always ensure the BMS and system wiring support the combined currents.
