Question about Feelworld FW759

Apparently it is battery operated. Neither the battery nor the cable for the battery is included in the delivery content.

Here are the contents of the kit:
1 × Mini HDMI cable
1 × Lens hood
1 × Hot shoe mount
1 × Battery plate F970
1 × HDMI socket lock
1 × User manual

Normally it is this, according to what I found:
