I finally got my first box mod built and it worked awsome, battery lasted about 6-7 hrs when I went to open it up to take out the battery there was a bunch of white chalky kind of powder in the inside of the box stuck mainly to the back side (the half with out the parts and batt) 
Did I do something wrong? well I am supervising the charging now Hope nothing blows up,,,, has anyone else heard of this or experienced it?
