B- and GND

[67exec]

putting a dna 60 in a vapor flask clone, and I'm sure that I can just hook the B- and the GND together, but checking first.  The daughter board was broken in the device when I got it, so it had to go by the wayside. Next question is, should I run a jumper from B- to GND, or run 2 separate wires from the solder tab on the 510? This mod uses the case as the B-

 

Thanks in advance

going through pinout again, and noticed that B- and GND are connected internally

That's right, you don't need a jumper on the DNA board, but I prefer 2 wires to spread the current and lower the resistance.

With 2 wires, can I run 20g-22g instead of 18g? Space is at a super premium w/o a daughter board
