A couple years ago I bought a 5v box mod from madvapes. I screwed on a new LR atty, dripped into it and fired it.. immediately popping the coil
I had no idea what higher voltage would do to a LR coil. I was so upset that I traded it to someone for a home made wooden 3.7 box that only fired intermittently.
