In the manual, two methods have been mentioned to power the FC
– Connect 5V power cable from ESC or UBEC to the ESC/Servo port, the J1 jumper must be closed.
– Connect 5V~12V power cable to the extend power port, the J1 jumper must be removed.
Now if you look at the image I have marked the pins used for both the methods.

So I dont think the power module is compatible with your FC since it has a 6 pin connector and was specifically made for APM with current and voltage info. Maybe you can use the module with some mod to power your FC only but why dont you use a Ubec instead?
V2 seems to be without the manufacturing defect but quality issue may crop up since its HK.
The module looks like this when soldered, the image may help you
