Hey all! Ive been vaping for 9 months now, and I have a lot of kanger tanks. No matter what battery I use, the juice I vape seems to end up burnt before I feel like the atty is truly ready to be replaced. For example, my current setup is an itaste vv and aerotank with 2.2 ohm single coil atty. Ive had the new head in for a week and I can already smell/taste burning. I use a chart to determine a range of voltage settings I don't really stray from on my itaste... what could I be doing better to prevent this unpleasantness? Thanks guys
