I just received some new Kanger T3's in the mail and my eVic will not register them. However, they will work on my ego-T batteries, but they are tasting a bit burnt. I've tested 5 coils on it now and same thing on all of them. However... I have two other Kanger T3's that I've been using on both the eVic and the ego-t's for a couple of weeks now with great results.Any thoughts on what the issue might be? Is there something not making contact on the Evic that is making contact on the ego-t's? I noticed there is what may/may not be a set screw on the bottom of the T3 coil head. Do they come from the factory screwed all the way down and I need to back it off or something?
