From what I understand this is an important part of the kit. If you want to use the BMPCC6K or BMPCC4K for professional use, a V-mount battery is required and this cable will allow you to use it. It has worked flawlessly so far and I'm willing to bet it will last for quite a while if not abused. Great affordable cable and I love the coil design. Even with a 1V bayonet battery, I can use it to charge my BMPCC6K all day long!
