Ok..can't get it figured out as to why I can't vape at 5V with any of my genisis attys. No matter what I do...the ends of the coil between the post and mesh glow..and in most cases break. Doesn't do that with my 3.7v mods. This has a boosted switch and circuitry to handle the dual and triple coils, which the maker said actually increased the amps, wonder if that has something to do with it??
It could, it may also be the wire you are using. I always use 32ga. kanthal a-1 because of it's durability. I have had my Genisis mods up to 6v with no problem. The ends will glow at that voltage if the leads are long and there is not a lot of juice on the wick or if the mesh is shorting somewhere.
I know you've been using Genisis mods for a while now so I would not think it's a short, just added that for good measure
