I love my 401 atomizers. I've been looking at a bigger battery on it, sans a big tube. The vapor4life batteries are 380mah, pretty respectable in a little stick. But I can't for the life of me find a 808/901 -> 401 battery adapter. Anyone out there got a lead on these things? I have a 901 atty I've been fiddling with but it just doesn't compare to my 401.
