I have two ego batteries. One is a smok Tech 900 mah usb passthrough, and the other is a 600 mah Smoov vv (twist type). They both have the same threading, whatever type that is. Today I bought a Vivi Nova mini (wrapper says "slim"). It's a Smok Tech, not a Vision. I'm feeling mighty stupid because the tank doesn't fit on my batteries lol. The threading on the tank is just a tad too small to screw into the ego threading. So I'm guessing I need an adapter of some sort. Is anyone able to point me in the direction of the correct adapter to make this thing fit? Thanks!
