To be honest, i'm not really sure what battery i currently have. I'm fairly new to vaping. I stopped smoking tobacco about two weeks ago. I am really getting into the hobby and want to upgrade to a variable battery or mod (whatever its called) but i don't know what tank and atomizer to get. I currently have the vivi nova 2.0ml tank and i'm not sure what the atomizer is. I just want to get the most vapor i can, but keep my nicotine level at about 18-24. If you guys have any other suggestions on what to do please let me know. I don't know if the vapor is controlled by the variable mod or the atomizer.
