I've been trying out these Kgo mega batteries and I love them, but now I'm starting to wonder if they're not junk. First one I tried worked great, so I bought I second. I charged it, put it on a smok dual coil cartomizer and tried to hit it, but the button just flashed red/white/blue really quickly and wouldn't produce any vapor. I messed around with it over the course of a few days and somehow managed to get it working again. However, yesterday I dropped the OTHER battery (the one that was working just fine) and now it's pulling the same thing too, and I can't get it work either unless I BARELY screw the battery to the carto. What does the red/white/blue flashing mean? I've done the gently pulling up on the center pin trick. It didn't have any effect. Does anyone know any other tricks or know what could possibly be happening?
