The SmallRig V-Mount Battery Adapter Plate with Extension Arm assists in improving the battery life of your run-and-gun setup. Compatible with most V-mount batteries, the adapter plate also provides two 14.8V D-Tap ports, an 8 VDC port, and a 12 VDC port to power your accessories and camera with ease. The dual-rod clamp mount can attach the plate to 15mm rods, and its angle can be adjusted with the included extension arm, while various 1/4"-20 threads allow you to mount accessories like a magic arm or super clamp mount directly onto the plate. Utilize the power switch to quickly turn all the ports on and off.
