Regarding building a 5v mod, what all do you need? I'd rather not buy the 5v box mod kit from Mad Vapes, just because I like finding cases around the house I can use, but I'm interested in building one.
Oh, I should clarify a couple things. Yes, I can solder well enough. I am familiar with building a 3.7v mod. I just don't know what I need for reducing the voltage from a pair 3.7v's to 5v. And why the heck isn't there just a dang 5v battery?
