What’s included and the basic form factor

This product comes as a single 48V 100Ah LiFePO4 battery module with a touch screen and APP monitoring capability built in for remote viewing. The physical size is compact compared with legacy batteries, measuring 19.3 x 15.1 x 6.1 inches and weighing about 90 pounds, so you can carry and install it more easily than comparable lead-acid units.

Key specifications

You’ll want to know the headline numbers before deciding if this matches your needs. Below are the main specs presented clearly so you can quickly scan what matters.

How to read the table

This table gives you a quick reference to the battery’s performance envelope and physical footprint. Use these values to compare with your inverter, charger, and space constraints to ensure compatibility.

Design and build quality

You’ll notice the battery looks compact and purposeful, with a server-rack-friendly rectangular shape and a user-friendly touch display. The casing and connectors are designed to support indoor and outdoor use, though you should protect it from direct weather where recommended by your system installer.

Materials and cell quality

The pack uses Grade A LiFePO4 cells, which are known for thermal stability and long cycle life compared with many other lithium chemistries. That choice explains the long lifespan claim (10,000+ cycles) and contributes to safer behavior at elevated temperatures.

Weight and portability

At about 90 pounds, you’ll find it significantly lighter than comparable lead-acid modules, typically about half the weight for similar capacity. That makes transportation, placement in tight spaces, and installation in RVs or server racks substantially easier for one or two people.

Rack and mounting considerations

Because it’s designed as a server rack battery option, you can plan to mount it in standard enclosures or on shelving with adequate ventilation. Keep in mind the center of gravity and secure cabling to avoid strain on terminals during movement.

Capacity, usable energy, and longevity

This battery offers a nominal 5.12 kWh of energy and claims 100% available capacity, meaning you can use nearly all of the rated capacity without deep cycle damage like you would with lead-acid. With a stated lifecycle of over 10,000 cycles, you should expect years of reliable use when maintained correctly.

Real-world usable capacity and degradation

In practice, you’ll get close to the 5.12 kWh usable energy, especially when your inverter and battery management settings match vendor recommendations. Expect only minimal capacity loss in the first several years, and a much slower gradual decline compared with lead-acid alternatives.

Built-in 200A BMS — safety and protection

You’ll benefit from the integrated intelligent 200A Battery Management System (BMS) that manages overcharge, over-discharge, over-current, and over-temperature protections. Those protections are essential for safety, especially if you run high loads or have multiple batteries in parallel.

What the BMS does for you

The BMS will balance cells, cut off output on unsafe conditions, and limit currents to protect both the battery and the devices connected to it. Because it supports a max continuous discharge of 200A, you can run heavier inverter loads but you should match your inverter’s current draw to these limits to avoid tripping protections.

Performance: discharge, continuous power, and peaks

With a maximum continuous discharge current of 200A, you’ll have up to about 10.24 kW available at nominal voltage, so many household loads and most inverter setups will be supported. For heavy peak demands, check the inverter’s surge requirements and verify that the battery can handle short spikes in coordination with its BMS.

Matching to inverter and appliances

Make sure your inverter’s continuous and surge ratings fall within the battery’s discharge capabilities. For instance, if you plan to run motors, pumps, or HVAC, factor in startup currents which can be several times the running current and may demand a higher peak capability or staged startup strategies.

Charging behavior and recommendations

You’ll find the LiFePO4 chemistry accepts higher charge voltages and faster charge rates than lead-acid, and it tolerates partial state-of-charge operation much better. Use a charger or solar charge controller configured specifically for 48V LiFePO4 settings to maximize battery life and performance.

Charge voltages and balancing tips

Charge to the manufacturer-recommended voltage setpoints (often around 54.6V for 48V LiFePO4 full charge, but confirm with vendor guidance). Allow the BMS to handle cell balancing and avoid leaving the battery at extreme states of charge for long durations to extend lifespan.

Monitoring: Touch screen and APP features

You’ll appreciate the onboard touchable smart display for immediate status checks and the companion app for remote monitoring and logs. These interfaces let you view state-of-charge, voltage, current, temperature, and event histories so you can manage loads and spot issues early.

What you can do with the app

Using the mobile app, you can monitor performance remotely, check historical cycles, set alerts, and potentially update settings depending on firmware features. This makes it easier to operate a distributed system where batteries may be physically remote from your living or control area.

Expandability: paralleling up to six units

If you need more capacity, you can connect up to six of these batteries in parallel to create a larger bank while keeping the system voltage at 48V. This expandability supports scaling for larger off-grid systems, bigger RV installations, or more resilient backup arrays for home or business use.

Important parallel setup notes

When you expand capacity, you should fully charge each battery individually so they reach similar voltage states before connecting in parallel to avoid large inrush currents. Also, wire the bank properly with equal-length cables and balancing practices to prevent uneven current distribution among units.

Use cases and suitability

You’ll find this battery well suited for off-grid solar systems, RVs and motorhomes, home backup, trolling motors, golf carts, and server rack energy stores. Its combination of weight, cycle life, and monitoring makes it versatile across applications that require reliable, compact energy storage.

When this is especially beneficial

If you rely on frequent deep cycles (daily cycling for solar/Ai systems or heavy RV use), you’ll notice a lower total cost of ownership compared with lead-acid due to the long cycle life and deeper usable depth of discharge. It also shines where weight is a constraint, such as on mobile platforms.

Comparison with lead-acid batteries

You’ll see multiple advantages over lead-acid: roughly half the weight, higher usable capacity, nearly flat discharge profile, faster charging, and much longer cycle life. While the upfront cost is higher, the total lifecycle cost typically becomes favorable if you cycle the battery often.

What you trade off

LiFePO4 batteries typically cost more upfront and require compatible charge regulators or inverter settings, but they demand less maintenance and provide dramatically longer usable life. If you rarely cycle your battery, the cost benefits might be less immediate, so you should assess your usage profile.

Installation tips and safety precautions

You’ll want to place the battery in a clean, ventilated area away from direct sunlight and extreme temperatures to maximize life and safety. Use appropriate cabling, torque the terminals to manufacturer specs, and incorporate fuses or breakers as part of your install to protect against short circuits.

Handling and transport guidance

When moving the battery, use two-person lifts or mechanical assistance if needed because 90 pounds can still be awkward despite being lighter than lead-acid. Protect the terminals with caps during transport, and avoid dropping or striking the case to prevent internal damage.

Maintenance and long-term care

You’ll spend very little time on maintenance compared with flooded lead-acid systems since LiFePO4 does not require watering or frequent equalization. Periodically check terminals for tightness and corrosion, confirm firmware/APP updates if available, and keep logs of cycle counts to anticipate eventual replacement.

Storage considerations

If you’ll store the battery long-term, maintain it at a partial state-of-charge (often around 40–60%) and recharge periodically to prevent cell imbalance. Store in a temperature-controlled environment to minimize capacity loss over time.

Warranty, support, and returns

You’ll get a five-year warranty with the battery, and the seller promises support within 24 hours to help diagnose issues and provide solutions. If the product has quality problems, they offer a free return and exchange service, which reduces risk when buying a high-value item.

How to make warranty claims

Keep your purchase records and any serial numbers handy in case you need to contact support. Follow the vendor’s troubleshooting steps and provide logs/screenshots from the APP when requested to speed diagnosis and warranty processing.
