what's with the red/green flashes on my charger?

Also, please dont use the USB's of your PC to charge these batteries. Screw the battery onto the dongle, plug the USB into a USB to Wall adapter and charge that way.

USB ports on PC's simply are not powerful enough to charge the batteries and can actually cause them to short out your PC or cause your batteries to vent (or worse)

Just the reason I went to a mod setup, sitting there waiting for that pesky green light only to drain it again, then I realized the term chain vaper lol

Yup, tis simply the batteries way of saying "nearly done mate, but don't rush me"

Maybe I could operate a similar system for the wife so she doesn't have to huff and don a bored face?
