Soooooo. Just got the ol dna 200 in the mail last week. Been vaping on it for nearly a week as well. Battery life is absolutely horrendous and I doubt my high wattage tastes help it either. I also cut down screen brightness to aid with this as well as making all the screens only show messages for like a second. Just wanted to give some feedback on the 1200mah 3s lipo pack. Otherwise works like a charm and the dna chip is incredible.
