6v usb rechargable nicostick?

[Jason365]

Is is possible to do this, I would like to build one from 2 cr123a's with a mini usb plug to recharge both batteries without fires or explosions. there are plent of the single battery usb rechargeable nicstix. why hasnt anyone done the 6 volt? what are the obsticles? Any of you guys like cybervex, or caesar want to chime in? Or any of you other guys that know anything about it.

THanks

You require 0.5v greater than the batteries being charged (destination voltage) to do this so its not possible to do it with a USB.

One solution would be to have a slide switch to set a 'charge mode' that would change the wiring internally to toggle from series to parallel. It's not particularly difficult so I'm not sure why it hasn't been done. The only downside would be that you could not vape at higher voltage while charging.

hmmmm. I must look into this more then. What would be a good size box for all this to fit in?

A battery box for 3xAA would fit everything pretty easy or you could use a 2xAA with CR2 bats if you're comfortable with unprotected bats.

Would you be able to run it at 5 volts while charging when if the switch was in the charge parallel position?
Configuring that switch to go from series to parallel sound tricky It looks like spaghetti in my mind. Any diagrams on doing that?

I found this does it make sense? look at the link for the correct diagram.

correct series-or-parallel-or-off switch wiring?
