This new mod has been updated to the Q2v2.
It accepts 1 17670 for 3.7 volts, 2 CR123 3.0 volts for 6 volt, or 2 CR123 3.6 volt for 7.2 volt vaping.
"Longer, lighter, and sporting intriguing design features, the Q2v2 is all new for 2011. From its softly rounded quadratic end caps, to its softly textured body, the Q2v2 is a pleasure to hold. It vapes hours longer at 3.7 v than all other Copper models, using a protected 17670 battery. For vaping at 6 v, this model accommodates two protected (3.0 v) 16340 batteries, which is compatible with all atomizers. The Q2v2 runs longer, and performs as good as it feels!"
