Have not seen them sold but you can make your own from two dead 901 attys.
Dismantle them, use the tube from one, connect the center post and push the second connector on the other end.
With current atties, when you take a draw, small droplets of e-liquid are drawn from the metallic wool through the hole in the center of the ceramic pot on to the hot nichrome wire.
If the nichrome or any other heating element would be pooled with liquid, it wouldn't have the necessary heating...
Excellent, it looks perfect.
Already drooling here!
I'm going to find a shop that will do it for me or I'm going to get all the tools to make it myself! :D
Just a small request: could you pretty please post the switch part opened?
Black is a bit dull, so now it looks like this:
Pop those spray cans and let your imagination be free!
PS: remember to protect it with some varnish after the paintjob.
It works, just not practical for anything larger than a 10400.
Count on 3-5 hours charge time for a 10400, 9-15 hours for a 14450, 27-45 hours for a 18650.
It's way better and safer to use a 6V power supply and wire the attys in parallel rather then using 12V and wiring them serially.
If one dies slowly on 12V (serial connection) it will suck the life of the other one too.
Look after a 3A (minimum) switching power supply to cope with atty...
I use a copper pipe cutter to cut the tube 1cm down from the connector then some sharp tools to split along the last cm of tube and the connector will remain untouched.
My first was opened using Shreck's suggestion, then used the above mentioned method.
RIP mosfets, ESD is a *****.
Don't wear anything that can charge you electrostatic while handling them. ESD protected soldering station is also a must.
Pretty nice light effect!
Pipe is 22mm in diameter with a 1mm wall thikness, so inner diameter is around 20mm. Protected 18650 batts are a little thicker then 18mm so there is around 1mm space.
That's why I called it my take on a copper mod :D
There are many variations, this is just one of them.
I like small buttons...
Thanks for the kind words. I just hope more people will be able to do this at home, it's relly easy.
Besides the parts list I've used a drill and a soldering iron.
You can use any USB charger sold for normal e-cigs also, just couple it with a manual battery adapter so you'll be able to screw...
Yes, silver solder just tried it. It was a new battery, never charged and lasted 5 hours without a drop in vapor production, then I let it charge overnight. A 900mAh lasts me for 10ml of juice so this one should be good for at least 20ml.
I prefer counting in ml then in hours as everyone vapes...
This is not for sale, I am just showing that using some copper pipe and paper to fix the parts in place anyone can throw a big battery mod together.
Just passed a store that had all those nice copper pipe fittings and thought why not?
And the monster was born:
Li-Ion, 2200mA, 18650 type...
I just got the PCB's I've ordered 2 hours ago.
If there is interest in just the PCB or complete soldered PCB then I think I have to register as a supplier, right?
Crash, I have your back with a dremel!
Interesting, the black and red 18650 and 14500 from DX don't blow and the protection survives when shorted indefinitely. Tested myself when I forgot my multimeter on amps and tried to check the voltage :shock:
Using a mosfet to drive the circuit is cheap...
