Overcome power limitations with the D-Box V-Mount Battery Plate, a custom-designed solution for the Blackmagic URSA Mini and Mini Pro Cameras. This high-quality, durable battery plate offers power distribution, standardized remote start/stop, and hot swap capabilities for a variety of Blackmagic URSA Mini Pro models, including EF, PL, B4, and more.The D-Box V-Mount Battery Plate attaches directly to the back of the camera body using a special Molex connector, eliminating the need for external cabling. It seamlessly interfaces with the rear LANC port, enabling the D-Box to control the camera's run/stop function. The connectors on the D-Box are contoured to match the URSA Mini's, ensuring all cables can be installed without any collisions.This professional-grade battery plate communicates with the camera, allowing any ARRI standard start/stop trigger to be used with the 3pin Fischer port. The DC input on the D-Box is a Mini 4pin XLR, and the kit also includes a pigtail cable that converts to a full-size 4 pin XLR, providing the option to connect an AC Power Supply or External Power Plate. This feature enables you to power accessories and the camera during a battery change.When both battery and DC input are utilized, the D-Box defaults to the DC input, leaving the battery fully charged. The authentic IDX V-Mount plate provides 2x D-Tap (unregulated) on the power plate itself. However, one D-Tap may be obscured by the right side BNC connectors when in use.
