Maxi Roughstack battery question

[timnav]

Backstory (not necessary reading for the question at hand):

So, I ordered my RS in January of this year and I've been vaping away at 7.4v using 2 18350's to get the job done. Recently, I've had difficulty finding the joyetech "HV-6" high-voltage atomizer (anything else didn't seem to last 1/4 as long as those). So, I switched to using a single 18650 battery @ 3.7v and a 1.5-2 Ohm atomizer. I've been using the betterlife 3 hole dripping atomizer (I drip of course), and I love it. The only problem is I have a bunch (6) 18350s with lots of life left in them, and only 1 18650. I don't want to have to buy a bunch of new batteries if I can use the old ones.

Actual question:

Is there a way I can safely use a single 18350 in the space designed for an 18650? I first thought of using a wad of aluminum foil as a spacer, but that seems dangerous. Thoughts?

Thanks in advance for your help, ECF!

I would agree. It does sound very dangerous.

Bumping this back up to the top so that someone more knowledgeable might be able to help you with some ideas.

Def not foil, but how about a solid pc of aluminum stock cut to 30mm length and a rare earth magnet stuck to the bottom of the 18350 if needed to make contact. You can uy aluminum stock at any home improvement store, 16-18mm diam will work fine.

It's not so much a danger as a logistics problem. Usually the space that is reserved for a battery, and the spring of the unit, do not allow for different sized batteries to be used. You can try it, but you do so at your own risk. I do not claim to be an expert in theoretical battery size swapping. I am of the mind that if you are dead set on doing so that Alpman has a good suggestion. Spacers may bridge the gap between spring and battery post.

The Maxi Roughstack was designed for a variety of battery combinations. Two of the four options are 2 x 18350 (7.4v) and 1 x 18650 (3.7v). The other two I haven't used, but basically there are 2 x 3v batteries you can put in there for a 6v option or another single battery at like 5v. I guess I can see about getting an aluminum core cut at home depot.

I forgot I posted here and just went with the foil last night while my single 18650 was charging. It worked. No fire. I did only put the foil in there while I was actually vaping, taking it out as soon as I took a couple hits.

Thanks for the advice, folks!
