Help? Have a question. Last night I filled a carto, and tank, then put it on my battery to vape it and the light on my battery stayed on for like 5 seconds solid before going out. I didn't get any(or very little) of anything out of it. I took it off, wiped everything off, tried again and got the same thing. I tried it on another battery, did the same thing. Then I tried another tank(on the original battery) and it was fine. (using the ego starter pack smaller batteries, not the twist) Is it possible that maybe the carto was bad(it was brand new, but I'm sure once in a while there's defective ones) and the battery was telling me something was wrong? (if only they could talk!) Has anyone else had this problem? I put that tank aside and will change out the carto later, since I think that's probably the problem but I didn't feel like messing with it last night. I had other tanks to fill. But I thought I'd ask and see if it's happened to anyone else. Any advice/comments/suggestions/answers, etc would be appreciated. Thanks!
