That light will be my first modded pipe. Take the bulb out and add the atomizer. Remove the clicker from the button and presto! Super-cig! It's a single aa cell light even though it looks bigger in the pic.
if a person has the skill using a suitable flashlight body as a battery holder is the way to go.. it aint quite as easy as taking the "bulb" out and the "clickly" out of the switch thow... he he
but if u break an e cig down to its basic components its simply a battery holder.. a switch.. and some means of attaching the atomizer..
thats all a lady pipe is.. its all an SD is... something that takes an AA sized 14500 battery (fourth from the left) is a nice starting point..
some suitable off the shelf lithium cells to think about.. they go from 300 mah on the left to 5000 mah on the right.. find you own battery holder.. torch bodies are the obvious thing to go for..

ps.. the lady pipe size is the third from the left.. the little thing in the middle is a 901 battery cell.. the thing we call the battery (little tube) isnt.. its simply the battery holder..
ps 2... those orange ones in the middle are the original ruyan e pipe size..
ps 3.. the pic is part of my off the shelf lithium ion battery collection..
