Since I got my Pcc I don't have a need of huge batteries any more. I've been looking with love at this 510 Mini eGo Battery (400mAh,3.7v) [C-B7 Vision 510] - $10.50 : Healthcabin Electronic Cigarettes - Wholesale and Retail maybe someone can tell me how good (or bad) they are. What worries me is the voltage regulator, I want 3.2 all the way. Seems these aren't regulated, should I get myself an eGo 650 instead?
