ok... I have a fairly big and frustrating problem...
i bought about 10 ego-t type b attys from vapor hawk, china thing,
either way, most of the attys work decently, then when I take them off the battery and blow the
juice out to switch they stop working, and then sometimes they magicaly start again. Plus i am using them on ego twist, i like it at 4.0 V.... oh and i drip.... so what am i doing wrong??
