that was not a typo. I ran it until it would not fire then fired a few more times lol. battery was at 3.2. I mean some say it is okay to let a regulated device catch it. I agree, 3.2 is killing the cell. other than an explosion batteries are cheap. I have vtc5's that I seriously abused. running to 2.6 in mechs for a year. they still held a charge but I did myself a favor and retired them. I think we all know these are nothing to play with. I just wanted to test the sx mini. I can reasonably get 17k. I use the kanger ni200 coils. I am disabled. I am currently running 520f,36j on them. I know that is very high but I like it hot. these are real good coils. sometimes my grandsons or great grandsons will build my tobh. obviously I would prefer that. the kanger is decent though. I know I said this but regardless of your feelings the 350j does more than the dna40. I think that is pretty much given. if you need all that to vape I don't know. I honestly think it would be better to use a discharger than try to figure out joules. I really do not think the 350j will let a battery explode however. it even says if it is overloaded. I would not rely on that of course on a regular baises
