if the bottom firing button isnt coming up to make connection with battery you can normally take it apart compleley and solve the problem with the aid of a spacer/washer . had similar issue with a mech i have that came with some extras washer in the bag and just needed to add one to extend the bottom firing pin uplift
The bottom button is coming up fine, I have just took the positive pin off and it is literally just a pin. Nothing else, just the pin. No spring nothing.

Just an update on this, seems as though I got it resolved and it is now working with my Fogger V3 (It was a connection issue but I managed to find that the Fogger has a bottom screw that lets you change the length of the 510 connection made this longer and it fired straight away - I'm still new at this ) - Doesn't work with PT2 but I'll just use the MVP for that.
