B-Mount Battery – 28.8V / 293Wh


The B-Mount Battery is a cutting-edge battery system developed by ARRI and Bebob to establish a new industry standard for digital cinema and video production. It offers advantages over traditional batteries, including real-time communication between the camera or luminaire and the battery, smaller battery plates, and various power specifications. ARRI also offers two chargers specifically designed for the B-Mount Battery.


The B-Mount Battery is a cutting-edge design jointly developed by ARRI and Bebob. It has been created to establish a new, future-proof industry standard. Compared to V- and Gold-Mount batteries, the B-Mount Battery offers several advantages:

With additional data pins, the B-Mount Battery allows communication between the camera or luminaire and the battery. For example, it can report the status of battery capacity and cycles.

The internal release mechanism of the B-Mount Battery allows for even smaller battery plates than with V- or Gold-Mount plates. This is a significant advantage, especially as cameras continue to shrink in size. The new release mechanism also facilitates quick battery changes while on set.

B-Mount batteries are available in various designs and power specifications, with a minimum output of 15 amps at 24 Volts. Our chargers can charge the batteries with up to 4 Amps of current.

We also offer two new chargers specifically designed for B-Mount batteries.
