I bought an eGo Twist and the dripper's bundle from Vaporcigzz.com My Protank worked fine with my eGo so I knew that the battery and connection was working fine. it seemed that the atty wasn't making a good connection with the battery. I found that there's what seems to be a spacer nut that comes on the atty connector. I removed the spacer nut and my 306 atty is now making a good connection with the eGo Twist battery and is working fine.
I hope this helps
