Another Nova guy here. Grew up in Herndon and now live outside of Warrenton. I have yet to go to any shops as most are a good drive for me, hopefully something opens up close buy as I am pretty new to vaping. Started with a smaller ego type battery and just a plain jane clearomizer. As of yesterday I am a proud owner of a Magneto and Aspire nautilus tank, what a difference. Does anyone have an idea how long the coils last as well as the 18650 batteries? The batteries I am just wondering how long they will hold a charge.
