Got me a few new T2's. One of them will not make contact with one of my eGO Twist batteries. I have anothert eGO Twist that it works fine on. I also have two other eGO regular batteries that it works on. It's just this one Twist battery it doesn't make contact with. I've tried other T2's and other devices on the "bad" eGO battery and they all work fine. It's just this one specific T2 on this one specific Twist that it doesn't work on. My guess is it's probably missing contact by only a few thousandths of an inch because I have, in the past, been able to get a half vape off of it. I initially thought it was lanyard interference but it's not because I'm not using the lanyard now. Any simple fixes without breaking out grinders and soldering irons? Thanks.
