Is your Twist a Joyetech? Does it have joyetech or eGo-c trademark on the lower part of the battery? Where did you buy it? And where did you get the T3?
This just in from Wayne, proprietor at heaven gifts who is in close contact with joye and kanger. (referring to the earlier thread on this issue)...
"I am also using twist battery+tabacc, it's working well and there is no problem like the thread says, I guess that customer is using a copy twist battery. Joye tech have two different eGo threadings, one 5 threads another 7, both can fit the Tabacc BCC. However, some Tabacc cartomziers center connector may not well contact the center connector of Joye series batteries, it's easy to resolve this problem, you just need to use a small screwdriver or a bamboo skewer to wiggle the center connector of Tabacc BCC out of its rubber seat a little bit, so that it would become higher, then it can well contact the battery connector. Joyetech don't have other eGo threadings, so it's not true that Joyetech has changed the eGo threading."
