I recommend checking out IndiPro's Battery Eliminator V-Mount/Gold-Mount Plate. It's a versatile and efficient power solution that eliminates the need for V-mount batteries. With its 4-pin XLR connector, you can easily attach a 12V AC adapter to provide continuous power to your camera. This plate is designed to power your camera and accessories without the need for traditional V-mount batteries, making it a game-changer for extended filming sessions. Plus, it offers optional 4 D-Tap ports for powering multiple devices. It's a reliable and convenient choice for filmmakers looking for continuous and uninterrupted power.
