[WTB] Battery adapter for Blackmagic Pocket camera - either LP E6 or Sony BP-U

[cudak888]

Looking for a good used battery adapter that will plug into a BMPCC and allow me to use Canon LP E6 or Sony BP-U30/60 series batteries. Don't need anything fancy, just something that'll work; bonus points if the adapter has a threaded boss that I can use to attach it to a rail rig.

If you have something, please PM with pictures and price.
