Longest cells that fit in a thrunite 1C

I’ve just purchased a Thrunite 1C Archer while out of town and am waiting to get back home next week to see if my RCR’s will fit or if I have to stick with Primaries. Does anyone know the longest cells it can take?
My only RCR’s have a protection PCB on each end and are extra long, to long for several of my 1x twisty lights. Should I go ahead and order a 12pk of CR123’s now or should my dual protected RCR’s fit?

I have the Neutron 1C which I believe has the identical body. It should pretty much take anything you put in it. I always used Trustfire Flames and more recently, EagleTac protected 16340s. I have it in front of me now with an EagleTac in it, and I can press the battery down about a half inch before it bottoms out the spring. You should be hard pressed to find a 16340 that doesn’t fit.

That’s good to hear, thanks.
