I was wondering if anyone has made a single 26650 dna30 or dna20 box mod. I have been cruising the site but I have not seen anything like that, one was dual but it was confusing to look at. Can the dna30 or the dna20 charge a 26650 battery? I have a couple of ideas of that I want to use such as the chi yu top cap, the firing button, and the tactile switches. I really would like to know which box was used for a single battery mod. I have 2 5000mah 50a sonys and one will be used in my Hades mech mod. Sorry about all of the questions but I really would like to make my own variable wattage mod.
