I'm in need of some help. I started out with a set of KR808D 1 batteries from Smokeless Image and then upgraded to a 5 volt OMG mod from Vapor4Life. I recently read a string of horror stories about stacked battery mods being a terrible idea, including my very own OMG mod. I would very much like to move to something more durable, with longer battery life, and less chance of explosive disassembly. The Silver Bullet seems to fit the bill nicely, but with one hitch. I've fallen in love with my dual coil tank setup, and have heard about lackluster performance at 3.7 volts. ALl I want is something close to the hit of that 5 volt hand grenade. Can anyone with more experience help me out?
