In principle, such cameras can be operated with an additional V-mount plate and such a battery. I assume that the power is sufficient for the camera. The advantage of this battery is its relatively compact size.
That should work. As far as I know, the Godox lights with battery operation can only be operated at a lower output. I'm not quite sure about the percentage value, but mine are limited to 60% output and more is not possible with a battery. 100% is only possible with mains operation.
Hello SandroR830, this should fit without any problems. The V-mount interface is compatible regardless of the manufacturer. Have fun with the Godox VL-150!
