Hi there Im in a bit of a pickle . I have two packs of LR attys from Liberty flights . I've been using one atty for about a week no probs them yesterday it started not heating properly , it would heat but vapor production was very poor . So I changed the atty and charged the battery . New atty and battery working perfectly for about 5 hours then all of a sudden the new atty would not heat , the battery led would stay solid and like it was heating but the atty was not getting hot then when I release my finger the led would flash 5 times . I put the old LR atty back on it and it would heat but not get hot . I then tried a standard atty and hey presto that worked fine. So then tried another NEW LR atty and that now seems to working fine , but I dont know for how long . Can anyone help cos I can't afford to be using and atty a day lol .
