Yes, they fit. It is pretty tight with a stock tailcap, but it works. If you want to go super-elegant, FiveMega has a deep 2C tailcap. I have the pleasure of owning two of these:

Unprotected 18650s will fit without any problem into a 2C if you remove the spring (you will need to deanodize the inside of the tail-cap for conductivity). For protected 18650s, I have read in this forum that you could fit them in if you move the stock switch nearer towards the bezel.

I'm not sure if theres much metal to machine in the tailcap is there? I need to cram some 18650's into my 2c, but you cannot do up the tailcap when I try. 
I'm gonna have to try to move the switch if I can... I only need 3 or 4 mm more space then the tailcap can be done up.

I just took the spring out and use a bit of aluminum foil to power these lights:

The original ROP LE uses all the stock parts in a 2C. You just deanodize the inside of the tailcap, cut the spring, and stick it down in the bottom of the cap. Nothing to buy (except some lye).

I run two unprotected 18650 driving a Lux V in a 2C. It is a tight fit with no spring. I took the deanondize route which is kind of time consuming, but ends up looking a little nicer than scraping or grinding would:
I can't imagine two protected cells fitting in my light. Had FiveMega's tailcaps been available, I would have grabbed them.

Guys CPF member Download can help you out with a "MAGRING" if he has any left, a good way of getting the extra few mm you need to fit protected cells in. Just a few dollars and it includes a solution for a contact - nil technical skill needed

FiveMega also sells a battery extension tube for this purpose.cd-card-biz said:

Unfortunately he's run out of c sized extension tubes, but the ring thing looks like it should work. Thanks for the info, I thought I'd be stuck with 18500's until now.
