Today at 1 pm I replaced my 18650 AW IMR battery in my Vamo (the battery was charged the night before). I used it a lil bit whilst walking to work (was having problems with my coil in my aerotank... it kept reading low ohms when screwed on to tight... stupid stock coils!) I was using it not long ago and all of a sudden it red Low ohms and I unscrewed it slight (as I've been doing when it does this) and it wouldn't fire or anything... It wouldn't do anything even after I took the entire tank off... I'd used it maybe a total of 45 mins - 1 hour at 10 watts... My question is do you think the battery could be faulty? When I put them into my Vamo they usually read 4.1v instead of 4.2 as they should after just getting off a full charge.
