About the BYD B-Box

Safe Battery Chemistry

The BYD Lithium Iron Phosphate (LFP) chemistry is recognised as one of the safest Lithium chemistries currently in use.

Safe Battery Construction

Built with the same battery modules as BYD's Electric Vehicles gives these 'stationary' battery systems the durability of devices designed for motive and high vibration applications.

High Power Output

BYD's High Peak Discharge capability makes them ideal for off-grid applications where surging loads are used.

Usable Energy Ratio

With smart design the B-Box can deliver a usable energy ratio of 96%!

Easy Installation

The B-Box systems have been carefully designed to simplify installation. The modular nature of the system components means they can be installed by a single technician.

Flexible Extension

The modular design also allows for flexible expansion of system sizes over the whole lifetime of the system!

Natural Cooling

Using natural convection cooling allows the B-Box to achieve the highest system efficiency as well as enabling operation without the noise of fans or pumps.
