Sparkplug / Thermo Battery Compatable Combinations ? HELP

[abraxis669]

Hello,
I have a sparkplug mod with the thermo tube.. and I was wondering all the battery combinations that can be used with these. I know about cr123s / 16340s but what else? I've heard this can be used at many different voltages and I would like to be able to do this.

Thanks in advance for any help!!

A 17670 will fit in also- good for 3.7 volts with an LR atty.

I'm using a 18650-sized 4.8v 600mah battery in my Thermo. I found 6v to be a bit too harsh, so I stepped it down and it's working out well. I had to use a rare earth magnet on the batt to complete the connection (it's a flattop battery), and it's unprotected so I'm kind of wary about that, but overall I'm really pleased with the vape I get from it.

They really are terrible PVs. I bought the SP1 which comes with no-name unprotected cells. When I use a protected TrustFire16340 (the white one) I can not screw it together properly. I ended up using some o-rings to cover the exposed threads.

My sparkplug & thermo thread all the way w/ all the batt types I've used so far.. But my switch has become a PITA. It wasn't working whatsoever but I took it apart and used a 3-sided nail file/buffer/shiner type thing to shine up all the contact points and now it works much better.

Pathetic switch design also. For it to make a complete circuit the shaft of the button also has to make contact with the sides of the hole it slides through. Pay attention to that area and keep it shiny clean.
