I'd like to see a wood Box Mod, or a metal Box Mod, or any cool small Box material you can come up with, just not plastic,, using a pair of these Batts = 3500 mAh HTC EVO 3D Li-ion 3.7V battery or one better with higher mAh.. And the batts where installed back to back on each other or only a thin piece of Milar in between them, and making the Mod so it is as thin as possible, putting a decent Chip in the Mod so it was variable from say 3.7 to 6--6.3v ish, has a drip well for the Atty, with a Green or Blue LED showing the voltage, and the electronics must monitor the Atty resistance like the Darwin does. could even be variable watt if ya got the know how, if not then VV, but must monitor the Atty's resistance. Also making the Mod as small as possible utilizing those Batts.
I think that's a pretty good start if ya can handle that then I got Dibbs on one of them

and good luck Azish in meeting the challenge.
