Will two 18350 batteries fit in a c6 host? Yes!

[Shady At Best]

I did a search for this subject and found mixed info on it. Some said yes some said no. Some said only flat tops would fit some said button tops would fit.
I was surprised to only find one thread on lpf about it and it ended with no conclusion.
I didnt want to buy some batteries online only to have them not fit.
Cruised by the local hipster hangout (planet of the douche bags, I mean vapes) and they have some aw imr 18350's. I tested two and they fit. Its a tight fit but the cap closes all the way.
Finally, I can run my laser at 8.2+volts and keep it in its compact configuration.

You could also use 16340's they fit fine. As do cr123's

When someone needs 2 batteries in a C6 without an extension tube its probably best to buy 16340's unless you know what kind of 18350's to buy because some will fit and some wont.
