I bought a man batt for my 901 so i could try to drip, and because(after watching a very instuctional video on youtube made by some goofy guy named chris) =) I have started taking longer hits, drags, draws, whatever you call 'em and my auto batts shutdown. So i was all excited put it together, fully charged it and ,prepared with some of my lung capacity returned, to take a nice long slow 6-7 second draw and after 5 seconds the damn orange light blinked. I was pissed the f-ing 901 man batts still has a 5 second timer. I was like WTF ok sorry for the rant but it doesnt say on any site i found that they have a shut off and i didnt want anyonelse to get one thinking they could take an 8 second ride on a 901 finally.
happy vaping
