The most flexible battery mount of all time

B-Mount® Battery Interface

The B-Mount battery interface is an open industry standard endorsed by ARRI and developed by bebob. It offers significant advantages over previous systems, including high power and multi-voltage capability, smooth mechanics and universal battery communication.

Cross-compatible with popular on-set camera and lighting equipment from manufacturers worldwide, the B-Mount makes it possible to supply all devices on set with one single battery system.

High-Power Batteries
for Cameras & Lights

Streamline your power needs for easy and efficient shooting:
The B-Mount interface offers maximum flexibility regarding the choice of batteries and accessories on set.

It has three times the potential to meet increasing on-set power needs than traditional 12V systems – offering a sustainable solution to meet the increasing power consumption of modern cameras and lighting.

One for All – 24V and 12V

B-Mount batteries from bebob provide 24 Volt high-power but also support multi-voltage (both 12 Volt and 24 Volt) – widening the range of equipment that can be utilized on set.

Furthermore, bebob offers customized V-Mount and Gold Mount adapter plates to power various cameras and lights with B-Mount batteries.

Being adaptable for the respective needs of each device, B-Mount batteries make it possible to supply all devices on set with one battery system.

FAQ

You are talking about 12V and 24V systems, but my batteries read 14.4V?
Today’s 12V Lithium-ion batteries read 14.4V nominal with 4s designs (using four cells in series in the battery pack). 24V Lithium-ion batteries read 26.5V nominal with 7s designs and 28.8V nominal with 8s designs.
Can I power my 12V devices with the B-Mount battery system?
Yes, our B-Mount batteries offer this opportunity. You need one of our 12V B-Mount power plates in addition, which will only pass 12V through from the battery to your device.
Which cameras and lights can be powered with B-Mount batteries?
We are continuously extending the range of compatible B-Mount adapter plates for the most popular cameras and lights. We are continuously extending the range of compatible B-Mount adapter plates for the most popular cameras and lights. You can find our available plates here.
