High-Safety 51.2V 16kWh Floor-Type LiFePO4 Battery with BMS and Wheels for Residential Backup




The 280Ah LiFePO4 battery cells offer large capacity, ensuring consistent performance while helping to save on material costs.



Safe LiFePO4 battery with smart BMS and integrated fire extinguishing aerosol — built for secure home energy.




Designed for convenience, the system offers a touchscreen, mobile-friendly wheels, quick installation, and true plug-and-play functionality.





How to work

1. Saving bill with PV
In the daytime, the PV will power to the load and store the excess power in the batteries. In the evening, use the power from the batteries to power the load.

2. Ensure uninterrupted power supply
When there is no PV and the grid power failure, lithium battery will take the load, to ensure uninterrupted power supply as power system.
3. Peak-to-valley spread arbitrage
Storing capacity on batteries when tariffs low using battery capacity when tariffs peak. Save on peak rate costs

1.  What is the main application of this lithium battery?
This battery is primarily used for home backup power, off-grid solar energy storage, RVs, outdoor activities, and small commercial applications.


2.  Is it compatible with solar panels?

Yes.  The unit supports solar charging and is compatible with most solar charge controllers and inverters.  MPPT compatibility is recommended for optimal efficiency.

3.  Is it safe for indoor use?
Absolutely. LiFePO₄ batteries are among the safest lithium battery chemistries. The system includes a built-in Battery Management System (BMS) for protection against overcharge, over-discharge, overheating, and short circuits. Additionally, it features an independent physical aerosol fire extinguisher for enhanced fire safety.

4.  How long is the battery lifespan?
The battery is rated for over 10000 cycles at 100% depth of discharge (DoD), which can provide 10+ years of service under normal usage.

5.  How long does it take to fully charge the battery?
This depends on the charging power. The battery supports a maximum of 150A charging and can be fully charged in 2-3 hours at full power.

6.  Is it easy to move?
Yes.  The battery comes in a vertical cabinet with industrial-grade wheels and a handle, allowing for easy transportation and positioning.

7. Can the battery be monitored remotely?
Yes, the battery supports Bluetooth monitoring via a dedicated mobile application. Users can check real-time battery status, including SOC (State of Charge), voltage, current, temperature, and fault alarms directly from their smartphone. This enables convenient and efficient system management.

8. Is the battery compatible with inverters?

Yes, the battery is compatible with most mainstream inverters on the market (such as deye, Voltronic, SMA, VE, etc.).


9.What’s the payback period for solar + lithium storage?
In many regions, especially where electricity costs are high, the ROI for hybrid solar + storage systems can be achieved within 2 years.
