The Hot-Swap Dual V-Mount Mini Battery Plate Power Supply Adapter lets you mount two mini-99 or micro V-mount batteries onto a standard V-mount plate for extended power to your camera, light, or other device. The plate provides two female V-mounts on one side and one male V-mount on the other side, allowing you to mount both the batteries, and you can mount the unit onto a camera or V-lock mount. Featuring uninterruptible power supply circuitry, the plate draws power from one battery at a time, ensuring longer overall runtimes. This compact, portable plate offers two 14.4V D-Tap outputs for powering accessories simultaneously with your camera. It is hot-swappable, so if you need to charge one battery, the other battery can power your gear without interruption. Status indicators on the plate indicate if the battery is connected and providing power.
