Mount two mini-99 or micro V-mount batteries onto a standard V-mount battery plate with this Hot-Swap Dual V-Mount Battery Plate Power Supply Adapter from CAMVATE. The plate's two female V-mount battery plates allow you to hot-swap your batteries without having to stop shooting to reboot your camera for longer, uninterrupted runtimes. The plate draws power sequentially—from one battery at a time—and LED indicators alert you to which battery is in use. Two D-Tap outputs are always active, drawing from the active battery. Weighing less than 10 oz, this plate is made of flame-retardant ABS plastic.
