You’re looking at a purpose-built 48V 100Ah LiFePO4 golf cart battery designed to replace multi-battery lead-acid banks with a single, lighter, and smarter unit. This PowerUrus-branded pack promises high cycle life, robust safety features, integrated monitoring, and enough capacity to cover most recreational or light commercial golf cart uses. If you value longer runtime, less maintenance, and better performance, this battery is aimed directly at your needs.

Who this battery is for

You want more range without frequent charging, reduced maintenance compared with lead-acid setups, and a lighter battery that fits into tighter compartments. Whether you operate a standard golf cart, a street-legal cart, a lawn mower, or a low-speed vehicle, this battery is built to be a plug-and-play upgrade for many of those uses.

Key specifications at a glance

Below is a clear breakdown of the most important specs so you can quickly see whether this battery matches your cart and expectations.

You should double-check the physical dimensions and charger requirements before ordering so you don’t run into fitment or accessory problems.

Performance and power delivery

You’ll notice a big jump in usable power and responsiveness compared with legacy lead-acid setups. The LiFePO4 chemistry gives you a steady voltage profile under load and a much higher usable depth of discharge (DOD) without harming cycle life.

You can expect strong acceleration out of the gate plus consistent power across the pack’s discharge window. The pack’s low internal resistance helps deliver higher currents to the motor with less voltage sag, so hills and heavy loads become much less punishing.

Discharge capability and peak currents

The battery supports a continuous max discharge of 300A, with short peaks available up to 600A for 5 seconds (or 550A for 10 seconds). That means quick bursts—like rapid starts, steep hill bursts, or short heavy loads—are supported without tripping protections.

From a practical standpoint, you get the ability to handle heavier carts, additional onboard accessories, or quick torque demands while retaining protection from over-current events courtesy of the built-in BMS.

Real-world range and driving feel

With 5.12 kWh of usable energy and support for 100% DOD, the battery can power most typical golf carts for roughly 40–50 miles per charge depending on terrain, load, driving style, and cart efficiency. That makes it a solid choice for longer course play, property management, or neighborhood transport.

You’ll also notice more consistent speed on inclines and less of the “weak downhill” feeling that comes from voltage sag in lead-acid batteries. If you’re carrying extra passengers or gear, performance will still be noticeably better than older battery banks.

What affects your range

Your real-world distance will depend on:

• Terrain: rolling hills or steep climbs reduce range.
• Load: passengers, cargo, and added accessories increase draw.
• Driving behavior: frequent stops/starts and high speeds consume more energy.
• Cart efficiency: motor type, controller, tire pressure, and mechanical condition matter.

Plan for a lower bound (for heavy use and hills) and an upper bound (unloaded, flat course) when estimating range.

Battery Management System (BMS) and safety features

Safety is built into this pack’s design. The integrated Max 300A BMS handles cell balancing and multiple layers of protection including short-circuit protection, over-current protection, over/under voltage protection, and temperature protection. That means the pack actively protects itself against the most common failure modes.

The steel case is fireproof, shockproof, anti-corrosion, and rated IP67 for water resistance. You get good physical protection against vibrations, splashes, and brief immersion situations—important when you’re operating outdoors in variable weather.

Thermal and electrical safeguards

The BMS will cut off charging below 0°C (32°F) and will cut off discharge below -20°C (-4°F), automatically re-enabling when temperatures return to safe ranges. During high-temperature conditions the BMS will also limit or cut current to prevent cell damage. These protections help extend lifespan and keep your battery operating safely in a variety of conditions.

Low-temperature operation and protection

If you operate in cooler climates, you’ll appreciate the low-temperature protection. Charging is disabled below 0°C (32°F) and discharge is disabled below -20°C (-4°F), preventing harmful lithium plating during charging and avoiding cell damage during extreme cold use.

You need to be aware of these limits so you don’t get caught expecting full functionality in freezing conditions. The BMS automatically resumes normal operation when safe temperatures return, so you don’t have to babysit the pack.

Practical tips for cold weather

• Keep the cart in a sheltered place or garage overnight to preserve battery readiness.
• If you must charge in cold outdoor conditions, bring the battery to above-freezing temperature first.
• Monitor battery state via the LCD or app to confirm charging/discharging status before heading out.

Installation and fitment

Installation is a straightforward process compared with wiring multiple 12V batteries in series. This single 48V pack removes the hassle of balancing series-connected batteries and most of the confusion around series wiring.

You simply place the battery in your cart’s compartment, secure it, plug in the external switch and connect the main power leads. The included LCD SOC meter also has a mounting bracket and hardware, so you can install the monitor where it’s easy to read.

Size, weight, and compartment check

The battery measures 16.14 x 10.83 x 10.63 inches and weighs 110.23 lbs. You should measure your cart’s battery bay before purchase—this battery is compact compared to lead-acid equivalents, but some carts have shallow or irregularly shaped compartments. Accurate measurements save you time and help avoid return shipping hassles.

Charger and wiring requirements

Because this is a 48V LiFePO4 pack, you’ll need a dedicated LiFePO4 charger, typically a 58.4V 15A charger to match the battery’s charge profile. Note that the charger is not included—plan to buy one if you don’t already have a compatible 48V LiFePO4 charger.

If you’re replacing a lead-acid setup, the wiring route is simplified since you’ll only connect one battery instead of several in series. Still, ensure your cart’s controller, fuses, and connectors are rated for the pack’s higher continuous and peak currents.

Electrical safety reminders

• Use the proper-rated fuse and circuit protection sized to the battery’s peak current and your cart’s max draw.
• Ensure solid, clean battery connections; poor connections create heat and voltage loss.
• Use the recommended LiFePO4 charger to prevent overvoltage or improper charge algorithms that can damage the pack.

Monitoring: LCD meter and Mobile APP

You get two monitoring methods: an LCD state-of-charge (SOC) meter and a mobile app. The LCD meter displays voltage, current, SOC, and basic status in real time, giving you an on-cart view of battery health and remaining charge. The app lets you view the pack remotely on your smartphone for added convenience and peace of mind.

This dual-monitor setup makes managing charge state easier and can prevent surprises mid-run. If you like tech that helps you stay informed, both monitoring options give you the data you need to be confident about range and performance.

What the LCD and app tell you

• Real-time voltage and current
• SOC (state of charge)
• Error or protection states triggered by the BMS
• Historical or live data via the app (depending on app features)

If you’ll be relying on remote monitoring, verify the app’s compatibility with your phone and confirm the Bluetooth or connectivity range for your typical use case.

Durability, cycle life, and maintenance

LiFePO4 chemistry is known for long cycle life, and this pack advertises 4000+ deep cycles. That’s significantly more than lead-acid cells and translates to lower replacement frequency and lower long-term cost of ownership.

The battery is maintenance-free—no watering, no equalizing charges, and no frequent cleaning aside from normal terminal checks. That’s a major convenience if you prefer spending time on the course rather than on battery upkeep.

Expected lifespan and real-world considerations

Under typical use conditions, you can expect many years of use before capacity falls below a useful level, but real-world lifespan depends on:

• How often you cycle the battery and the depth of discharge you use
• Operating temperature extremes
• Adherence to proper charging practices and use of a correct charger Balance heavy use with periodic shallow cycles if you want to maximize lifespan.

Size, weight, and space savings

At approximately 110 lbs and compact dimensions, this 48V 100Ah LiFePO4 battery is often about a third of the volume of an equivalent lead-acid bank and significantly lighter. That frees up space for storage, accessories, or simply better weight distribution in your cart.

You’ll enjoy easier handling when installing or removing the battery compared to lugging multiple heavy lead-acid units around. The weight savings can also make your cart more efficient, contributing to better range and handling.

Practical benefits of the compact size

• More cargo or passenger room
• Easier installation and removal for maintenance or storage
• Reduced strain on chassis components due to lower concentrated weight

Compatibility and use cases

This battery is aimed at golf carts but fits many other low-speed vehicles and off-grid applications with a 48V architecture. It’s suitable for:

• Golf carts and street-legal carts
• Utility carts and lawn equipment
• Small low-speed vehicles and custom EV conversions
• Backup power for small off-grid systems (where 48V is appropriate)

Make sure your cart’s motor controller and wiring are compatible with the pack’s rated currents and voltages.

Cart modifications and controller checks

If your cart originally used multiple 12V batteries in series, this pack typically replaces that configuration without rewiring—just ensure connectors and fuses match. If your cart has an older or low-rated controller, confirm it can tolerate the peak currents and has appropriate fusing to prevent damage.
