B-Mount

Powering the future

Representation of the battery plate, a 24 volt camera and a lighting system.
24 V open-standard battery system

The B-Mount battery interface is an open industry standard endorsed by ARRI and the wider industry. Providing high-capacity 24 V power, but also able to support 12 V, B-Mount offers more efficiency and improved data communication over previous systems. Cross-compatible with camera, lighting, and stabilizer equipment from manufacturers worldwide, it enables productions to streamline their power requirements.
