"A 18650" means one, just like "no such thing as a 5AH AA" doesn't mean a whole pack of AA's, it means one AA. The question I replied to was specifically asking about 18650 flashlights with handlebar mounts. Yes, there are some flashlights that accept multiple 18650's, but they are not generally handlebar mounted due to their size, where single 18650 lights such as this, for example are by far the most commonly used style of handlebar mounted flashlight. The question I replied to was not about arbitrary bike lights with separately mounted packs of multiple 18650s, it was about handlebar mounted, 18650 based, flashlights.

Then have a look - that one is advertised as 5, even, which is even more absurd. That's what I was talking about. These things abound, even on reputable sites like Amazon. Their claimed capacity is stamped on EACH CELL (not pack - there is no pack), and that's what I was trying to warn the person I was replying to about, as they often test at or below 50% of their rated capacity (which can be fine, as long as you realize you aren't getting what was advertised). I was attempting to be helpful by pointing out these false claims. I made an accurate statement that there are no 4 or 5 Ah 18650s (NOT packs thereof), and you claimed that my statement was wrong. It wasn't. I don't mind being corrected, but it helps if I'm actually wrong, which I wasn't here :). I tried to be friendly when pointing this out initially, but for some reason you keep pushing on it. It isn't helpful, and only adds confusion.

Anyway, peace - I admit to a bit of irritation when I wrote the above, so trying to end on a better note. Nothing against you - let's chalk it up to a mutually different view of the thread of conversation? Hope you enjoy whatever lights you run!

The issue is that you could have been clearer in your original post. Because Li-ion packs are constructed from individual cells they are often referred as 18650 packs. But for the use of a noun, your post would have been much clearer.
