RE: 9v mod
Hi and welcome Enouk!

9v batteries are designed for very small current delivery for a long time. They are not even close to being capable of supplying enough current.

Or for very long.

If you were to connect several hundred of them in parallel, maybe.

RE: 9v mod
Well most vape batteries are 4.2 volts so i think two 9v would be able to do it even if only for a few minutes

RE: 9v mod
It's the power delivery. 9V batteries can only deliver a tiny amount of power, which is defined as voltage x current. At 9V, you would need to pull one amp from a cell not capable of much more than 1% of that to get 9 watts. Which is pretty low power by most standards.

Here's the data sheet for a Duracell 9V battery. https://d2ei442zrkqy2u.cloudfront.net/wp...S12141.pdf

It holds about 600mAh of charge when discharged at 2mA or about 550mAh at 10mA discharge. 10mA x 9V = 0.09W.

RE: 9v mod
4.2 volts AND 20-30 Amps, no 9v cell is going to work in any kind of usable way.  
Give Don the benefit of the doubt on this one enouk, he knows more on the subject than anyone else I've met, period! 

Don't forget to apply for the freecycle section!

RE: 9v mod
You can make a suitable coil glow with one. Just. I didn't believe they could till someone pointed me at a YouTube video showing it. You won't get much vapour out of such a coil though.

There you go gently - a challenge for you. Build a mod to accommodate these batteries.[Image: tongue.gif]

About 10,000 of them in parallel and you should get something usable at 20A with respectable life.
Bit bulky though and I volunteer not to be the guy who has to wire it all up.
