I was a smoker (I know the dirty word!) and I moved to vaping to help me quit and I have fallen in love with it. I started off with a kanger evod and I loved it until I didn't. I wanted to upgrade without moving to the full on units/mods? (Still not quite sure on the proper names and wording) My local vape store basically told me there are the tanks like I have been using but only better or the systems where I build and use the cotton (Again, don't even know what "the cotton" is) I went with what sounded like the least work and got an Aspire Atlantis tank and Aspire CF SUBQ battery. I am happy with that (at least for now) but I prefer to have two batteries just for convenience so I don't have to worry when one dies. So my question is (I know finally!) for the tank I have should I purchase the same battery or is there a different battery that would be better all around. I don't feel completely comfortable asking tons of questions at my vape store so I'm hoping I can get help here. Thanks!
