Ok so this is my first ever mod, and shockingly except that it is so damn ugly, I love that it's perfect for my uses as far as utility goes. 4x14500 batteries, 2 in parallel, 2 in series gives me 7.4+volts @ 1800mAh. Basically I can vape all day and not worry about charging. I had to glue two old boxes together because 4xAA filled the battery box completely, the other box I used for the presoldered 501 connection only since it didn't fit the ciruitry I bought. Anyways my next mod is going to be with 4xAA w/ LM2596 + VVolt display. I've only got to find a good 510 connection for my atty and a box big enough. 
That reminds me, anyone know where to fix a 8xAA box? Thanks all
