48V Rhino - LiFePO4 - 276Ah - 14kWh


10 Year Warranty

SKU FWRHN-48140-G1 Category SKU#:

This isn’t just another battery, this is the RHINO! The RHINO is the thinnest and strongest wall-mounted battery on the market today. This battery is unmatched in terms of power density with 14kWh of capacity in only 4 in. of thickness.

Our goal in designing the RHINO was to surpass the “Tesla Powerwall 2” in every category. This unit comes with our advanced BMS and utilizes the safest and most advanced LFP cells available today to provide you with the greatest possible capacity, more life cycles, and a wide temperature operating range so no matter where you need power, you’ll have it!

Our RHINO comes with everything you’ll need to install it in your shed, garage, home, or wherever you’ll want to tuck it away. The wall mount makes it easy to place your RHINO wherever works best for you and the LED interface on the side of the unit allows you to monitor your battery’s health and status at all times. You shouldn’t need to spend $10k or more for a fancy logo, because the only spec “less” for the RHINO is the price tag. Order yours today!
