I've seen how people use all kinds of different batteries and have had made huge mods that contained lots of batteries. I went and found this: Your Online Source For 9 Volt Hitech 1200 mAh Lithium Battery and wonder why nobody has tried this yet? I'm no electrician, wouldn't even call myself a tinkerer in it really. But I could see limiting the voltage on this down to whatever you wanted, and being 1200 mah @ 9v, wouldn't it last longer than all these 1.5v multiple battery mods? Just an idea. I'm sure somebody will come along saying how it's one of those unsafe batteries that would explode like a land mine if it went out. Just an idea that ran through my head. I know I'm not the first one to think of it....
**edit** Plus hey, I know 5-6v vaping is all the rage, but 9v vaping, maybe it would instantly vaporize 3 ml of liquid in 1 hit and give you a massive nic buzz?
