Can someone tell me what the difference is between 510 and 808? The ones I would like to replace has a recessed battery connection or the threaded end. And when I order them do I need to look for a specific resistance. These came with a starter kit and I knew nothing at the time I ordered it. Their website offers filled cartomizers but no empty ones. I didn't realize how easy it would be to burn them up if they got dry and ruined most of them. I have a better setup now but think these would still come in handy. Any advice is appreciated.
Thanks
