The CXVM-FX6 mounts directly to the back of the Sony PXW-FX6. The milled aluminium product attaches into the top of the camera(with included screw hardware) to provide a secure platform for mounting v-mount batteries directly onto the FX6 camera. It has a 19.5v DC output with a visual low battery warning LED and a DC barrel input (OEM camera power supply) for hot swapping between external and on-board power. In addition, it’s equipped with a power tap and USB to power additional accessories. A USB firmware update port on the rear ensures future compatibility with camera firmware updates.

Up to a BP-U100 battery pack fits inside of the battery cavity on the camera, allowing the user to hot swap batteries. Once the v-mount on-board pack dies, it will automatically pull power from the BP-U battery and you will see the battery indication on the viewfinder change.
