Sorry for my tardiness...
For an auto battery... I suggest the 280mah kr808d-1 batteries. I do not sell these at this time, but have plans to in the near future. I understand that there is a definite need for a good mini auto battery. In the meantime, I can suggest a couple vendors if you would like to send me a PM.
The reason I recommend the 808d-1, is the pressure switch, and battery life. As well as the availability of cartomizers. A pressure switch is better than a microphone switch, for obvious reasons. These batteries are also available in 3 sizes, both manual and auto. So it gives you some room to play.
You can get a 901-510 adapter, and some 510 3'ohm cartos. I will be stocking 3.0 ohm 808d-1 cartos in a couple weeks.
Beyond that, I highly recommend the ego or riva 510, and Boge 2, 2.5, or 3ohm cartos.
I hope that helps.
I buy all my stuff from you except the the 280mah kr808d-1 batteries.This is my favorite when I want the feel of an analog and for when I'm out.When do you think they will be in? Please say you ordered some girly colors.
