It consists of a top plate, a V-mount battery plate, a side plate, a baseplate, and a power cable. Overall, the kit fits in well with Sony FX6 in terms of the design appearance, and color. Among these parts, the rear V-mount battery plate together with the power cable attaches the battery for an extra power source for prolonged operating time.
