ARRI has announced its support for the B-Mount as a universal 24 V battery interface standard. The B-Mount is a new open industry standard for battery interfaces developed by German battery specialist Bebop in collaboration with ARRI, which is intended to remedy the problem that modern digital cameras, accessories and rigs are increasingly pushing existing V-Mount and Gold Mount 12 Volt systems to their power limits. For example, the ALXA LF requires between 120W and 160W in standard operation with viewfinder and activated wireless video transmitter.
B-Mount, as a new high-capacity 24 V industry standard, is therefore expected to provide a future-proof solution to this growing power demand of professional camera and lighting systems, as per B-Mount can potentially deliver three times more power than conventional 12 V systems.
Since LED lighting is also powered by batteries, an industry standard makes sense for both cameras and lighting. ARRI has therefore already implemented the new B-mount battery interface in current ARRI cameras and lights, and will continue to do so in future models. The B-Mount standard is based on a universal protocol and is designed for robust construction in a compact form factor, and also offers seamless locking.
Another advantage is the possibility for extended communication between the battery and camera or lighting equipment. This enables, for example, a very accurate display of the remaining runtime as well as the charging time.
Batteries with B-Mount can be freely produced by all battery manufacturers due to the open standardization - so well-known battery manufacturers like Blueshape, Core SWX, Fxlion, Hawk-Woods, IDX and SWIT are already working on products with B-Mount. Bebop itself had already become the first manufacturer to launch B-mount batteries at announcing the B-mount standard at NAB 2019 and offers a whole range of B-mount batteries. ARRI offers B-Mount plates or adapters for all current ARRI cameras as well as for the SkyPanel S30, S60 and S120 lights.
