I just tested that out, and what do you know, the threads fit perfectly! But there's no airflow, and when I loosen it enough to get airflow, I lose contact. It might work with some 901 batteries, if they allow enough airflow, but it's a no-go with any of mine. But the VK batteries will power a 901 atomizer, so they're dual-purpose. AND, the atomizers will work on a Screwdriver, and get just barely enough airflow for mouth-puffing, albeit a hard draw.
Hmm, sounds like a whole new era of mods is on the horizon.. Thanks for that info Leaford!
