SmallRig 5881 Intelligent V-Mount Battery Adapter Plate with 15mm Dual Rod Clamp

A battery adapter plate for universal standard V-Mount batteries used to power cinema cameras, monitors, video transmitters and lighting.

The plate is mounted via a 1/4-inch threaded hole on the underside into the included 15 mm dual rod clamp. This allows the device to be integrated into 15 mm LWS rod systems for expansion with accessories.

Power Management and Connectivity

The system features intelligent power management with two operating modes toggled by double-pressing the side button. In combined discharge mode, multiple batteries are used simultaneously, while sequential mode uses batteries one by one. The unit has 4 D-Tap and 1 BP input, as well as 3 D-Tap and 1 BP output. Each output can deliver up to 100 W constant power.

A built-in 12 V switching circuit provides a stable 15 V output even when input voltage is low. A bidirectional USB-C port on the side supports up to 65 W for both input and output. A digital display on top shows the real-time status of all five inputs.

Operational Reliability and Hot-Swap

When using the included D-Tap to D-Tap cable, batteries can be replaced without interrupting power to connected devices. The system maintains a stable output of up to 100 W during the swap. If the 100 W limit is exceeded, a warning light illuminates and the output shuts down automatically. Under a continuous load of 100 W, the outer casing may become hot to the touch.
