Representation of the B-Mount for cameras and lighting.


Powering the future

24 V open-standard battery system

The B-Mount battery interface is an open industry standard endorsed by ARRI and the wider industry because it makes mobile shooting easier and more efficient. Providing 24 V power, but also able to support 12 V, B-Mount offers decisive advantages over previous systems. Cross-compatible with on-set camera and lighting equipment from manufacturers worldwide, it enables productions to streamline their power needs and source batteries locally.
