Designed to work with your SmallRig COB LED light (either daylight balanced or bi-color), the SmallRig V-Mount Battery Plate provides power to your light from its D-Tap output port. Simply mount the battery plate onto the lightstand supporting your light fixture and connect the included 5.9' long D-Tap to 3-pin XLR power cable to the battery plate and your light fixture for long run times without changing the battery.
