Hi all! This might be long so sit down (lol). Ok, so my husband and I are still pretty new at vaping. We started out with a starter kit from Vapor4Life and liked them alright. Then on a work trip out of state we stopped at a little vape shop to see what it was like. They sell Smokeless Image stuff. We tried some flavors and the cartos fit on our V4L batteries so I bought some. (The SI flavors are WAY better than V4L! But that's another story.) Well the next time I passed through there I bought a Mega PCC from the store, thinking that because the cartos fit on my batteries that it would charge my batteries just fine. Well it doesn't. Silly rookie mistake, I guess. Well when I bought the PCC the rainbow manual battery I ordered from SI was on it's way. It arrived and vapes great, but I can't seem to get it to charge on the PCC. I made sure the case was charged, my manual battery was low, and all the threads are clean. When I hold the button on the case down to charge, it blinks the "no battery" light then goes off entirely. Sometimes it will show some status bars for a second and the LED on my battery lights solid, then nothing. The LED flashes like it's low and I'm back to the beginning. Am I doing something wrong? Any help would be appreciated!!
