U2 and unprotected 18650s (fitment question)

I just got my U2 a few days ago, just got the plastic insert out last night, and just finished charging my new LG 2400mAh 18650s. On sliding a battery into the light I notice that the positive end of the battery is pretty exposed and flat (no button like on a protected cell), and I also note that around the inside of the bezel there's a metal ledge which I *assume* is in the ground path. Is anyone worried about the positive end of the 18650 touching that ledge and making a kaboom? I've just eyeballed it, so I don't know how close they really are to each other when the bezel is screwed back onto the battery tube. :candle:
