The double plate can be equipped with 2 V-mount batteries at the same time, then you can get the total capacity of two batteries, and mounted on V-mount equipment, to make the equipment long time working.
Two pieces same voltage, same capacity batteries are suggested to use with the plate. For example, if you use two pieces fxlion 14.8V, 265wh battery with the plate, you will get 14.8V, 530wh power.
If you need your V-mount equipment to work long time, we suggest you the other option: fxlion BP-F100U battery.
