DNA40 transplant into vf clone question

[AtmizrOpin]

I have a Waidea vapor flask with the Rayn V3 still in it. I have a dna 40 board on the way for it. I actually have 2 Waidea's, one black and the other silver. The black one I put a FDV V3 510 in and stopped there. But the silver one I'm going to go all out, FDV and a DNA40. Now I know I'm going to have to use the extra ground that's on the board to ensure a proper working mod. My question is, any thoughts on where I can put this ground? Space is minimal at best. Silver epoxy maybe somewhere? Any help would be appreciated. I'll post pics of my progress down the road.

I've just done a transplant into an infinite clone. What I did was solder one of these header pins into the battery negative socket on the board.........

I then soldered a wire into the OUT -ve, ran it up the board, split the insulation, soldered it onto the header pin, and let the wire continue up to the ground on the 510.

This way both negatives are connected to the 510 with a single wire. I have photos but not here, now.
