The Bebob Engineering Dual Battery Adapter for Sony F65 (V-Mount) is designed specifically for Sony's F65 camera. A plate similar in size to this adapter comes natively attached on the F65, and the adapter simply replaces that plate, using the plate's four screws. The F65 is a power hungry camera, and this adapter will enable attaching and getting power from two batteries simultaneously via a Lemo connection from the adapter to the camera. A Lemo-to-Lemo cable is included. The batteries mount on the left and right of the adapter.
