box mod 12v rda big boy clear mosfet 18650 dual

Bored figure id share this with you guys. Needed a heafty box for the large coils ive got goin on in my Big Boy rda so i built one with 2 npn power transistors and a large 12v battery pack. The other one i built for my exothermal rda that i never use. I was bored and felt it needed its own box...
