Ok so I have had the 5v WoW for a while and love it. I just purchased a DCT tank and got in today. I put it on and vaped until my nearly dead batteries gave up the ghost and needed charged. Replaced the batteries (2x 16340) and when i hit the button the light came on but no vape and the light wouldnt go out. I pulled the batteries and tried again light flashed, no vape, and nothing after. Pulled the batts and tried a few more times and it randomly does one of the above two symptom sets. Pulled the tank off and put on a Boge carto, works fine. SO... Any tips on getting these things to work with tanks? BTW tried the tank with both 1.5ohm dual coil and 2ohm dual coil, same thing with both.
