Blackmagic URSA Cine Battery Plate B Mnt

The Blackmagic URSA Cine Battery Plate B-Mount is a dedicated power solution specifically engineered to integrate with the URSA Cine camera system. This sturdy, professional-grade plate allows you to attach a single high-voltage, third-party B-mount battery directly to the rear of the camera body.

By utilizing this direct attachment, you can provide reliable 24V power to the camera and its accessories without the need for any external cabling. This creates a clean, streamlined rig that is ideal for high-end productions, ensuring the camera has the necessary voltage to unlock its full range of frame rates and resolutions.

Product Features in Detail

High-Voltage 24V Power Optimization

The URSA Cine is designed to operate at peak performance within a 24V to 34V range. This B-mount plate allows the camera to draw the higher voltage necessary to unlock its full potential, including high frame rate recording (up to 120 fps in 12K or 224 fps in 8K) and maximum sensor readout speeds. Using this plate ensures the camera is never "throttled" by the lower voltage limits of traditional 12V–14V battery systems.

Streamlined Direct-Attachment Design

Engineered specifically for the URSA Cine chassis, this plate mounts directly to the rear of the camera body. This integration eliminates the need for messy external "pigtail" cables or dangling adapters, resulting in a cleaner, more professional rig. The direct connection improves reliability on set by reducing the number of potential failure points in the power chain.

Integrated Regulated 12V Accessory Port

In addition to passing high-voltage power to the camera, the plate features a built-in 2-pin LEMO output. This port provides a regulated 12V supply, allowing you to power smaller accessories—such as wireless video transmitters or secondary monitors—directly from the battery plate without needing separate power splitters or D-Tap adapters.

Advanced Thermal and System Stability

By utilizing 24V B-mount batteries, the system operates with lower current draw compared to 12V systems. This results in reduced thermal loss and less heat buildup during long takes. For high-end cinema productions, this translated to a more stable operating environment, ensuring the internal electronics of the URSA Cine remain cool even during intensive 12K or 17K RAW capture.

Secure Locking for Professional Environments

The B-mount standard is built for the rigors of high-end film sets, featuring a robust mechanical locking mechanism. This plate ensures that heavy, high-capacity third-party batteries (from brands like Bebob, Core SWX, or IDX) remain securely fastened during aggressive camera movements, handheld shooting, or when the camera is mounted on jibs and gimbals.

Intelligent Communication Support

Designed as a "smart" interface, the plate supports data communication between compatible B-mount batteries and the Blackmagic OS. This allows the camera to display accurate, real-time data such as remaining percentage or runtime in minutes directly on the 5" HDR touchscreens and the status LCD, giving the crew precise control over their power management.
