The V-mount Tilta Power Pass-Through Plate Kit for DJI RS 2 attaches to the RS 2 gimbal in place of the standard camera sled and lets you power your camera and multiple accessories using an optional V-mount battery. When used individually, the Power Pass-Through Plate is designed to connect to the Tilta Power Supply Base Plate for DJI RS 2. But when combined with the battery plate included in this kit, it lets you simply attach a battery for power.
