All right then. I want to thank every single person that helped or provided links, or answered any of my questions. You guys are all awesome and have been a tremendous help in taking my vaping to the next level. All from one simple forum post, learned the comparisons between Cartos and regular atomized tanks, learned that wattage all comes down to personal choice with flavors and each has its own sweet spot, learned where to get resources, and what a dual or single coil can do for the experience. Now I just have one last question before I can call this a closed case. Where can I get a second battery for my Lava tube 2.5, does any particular company matter and are there some better than others?
