I started out with 510 auto batteries so when I decided to move to bigger batts I went with the eGo.I have a 1000mAh manual passthrough and 2 1000mAh auto batteries,problem I am having is that the autos quit working on me after about a week of use.They will charge to green but then do nothing when I use the atomizers even though the attys work on the passthru.I ordered them thru Cignot who have been nothing but outstanding with their warranty. Vicki says that autos are sensitive to liquid getting inside them and shorting out. Could someone please help me to increase my time out of these batts as I love them to death, I just hate that I obviously don't get along with them.Nina
