I work in the audiovisual/electronics field and I'm used to dealing with a bunch of different connector types but e-cig battery threading is giving me fits. As mentioned elsewhere, I'm an 808 user who's looking to upgrade his setup a bit without going to a new threading (yet). My 808 cartos/clearos work fine on my Triton battery, although they look a little funny due to the difference in diameter. I've got a couple of eSmart batteries on the way and these also accept 808 heads, and I noticed an "808 eGo" battery at Smoktech that's a bit cheaper than the Triton battery but looks an awful lot like it. So anyway, are "808 eGo", vGo, etc. really the same connector?
