An increasing people are using DSLR to shoot video or film, people love to use Sony A7 NEX-5 5R 5T 5TL a5100 a5000 a600. However they have to face an  unavoidable issue "POWER SUPPLY" The original battery can only last 1 hour, obviously it is not enough. The cameraman need to shoot over 8 or 12 hours per day, they can't carry so many battery, they need a new " Ammunition” to supply their big gun.
The FW-50P is the new" Ammunitions " , it can be connected to the outside battery resource(we also suply the V mount battery plate which can distribute the 16.8V into 5V,7.4V,12V,15V) so the camera can use the power from the V mount  (or Anton) battery, the capacity of the V mount is 8 time equal to the orginal FW50 battery. From now on the cameraman won't be bothered by the power supplying problem any more
