Greetings! I have purchased a Blu Cigs starter pack, and have received it via the mail. I charged the Blu pack (PCC I guess is the term) and then plugged a battery into it. Now, for a while the external LED blue light on the pack was solid, but after 15 minutes, the blue external LED began to flash periodically. Meaning the LED was off for a bit and then flashed blue, then off then blue etc. The instructions say once the external LED light turns off, charging is complete for the battery. But I can't find anything regarding the periodic flash, and Blu CS hasn't answered my question regarding it yet. Was wondering if anyone here could shed some insight? Thanks for your time.
