Is V6 compatible with studio flash set QIHE BJ 150?
... or any other QIHE flash ...
The V6 is compatible with any strobe that has a sync-connector.
You'd need a sync-cable between a V6 receiver and the strobe to connect them up. This cable does not come with a V6 but can be cheaply obtained.
Note, however, that this will only allow you to trigger the strobe. You won't be able to remote control the power of the strobe. Remote power control only works with supported flashguns.

This is the cable you will need for connecting a V6 (set to RX) to a studio strobe. Most of the strobes has a 3.5mm or 6.35mm sync port:
