I have 2 CR2 in series and when I try and vape with my Tankomizers (Volcano & Wicked) they will not work. Doesn't seem to be a problem with the regular 510 atty or the Clearomizers. The same problem exists when I try and vape my 808D-1's. Anybody know why/whats going on? Sorry for the newb question. What do I have to do to be able to vape these attys at the higher volts on my mods? What am I missing? Any help would be great. Thanks.
