18650 is an industrial cell specification. 18x65mm
They are lovely batteries, though a little scary sometimes. I'd make sure to put AW brand protected cells in that, from a reputable source not knowing how well it regulates current to each cell
As an E-cigarette vaper, I use tons of 18650s in my e-cigarette. You get what you pay for with them!
The technical term for what they do when you get one that fails is venting with flame. Which is about as exciting as it sounds(aka not fun, there's a user over on candlepowerforums who got hospitalized from a lithium cell going off) legally you can't even ship more than 3 18650s together.
That 4 pack looks neat, but honestly seems like total overkill to me. No wonder it took so long to charge, each of those cells could be up to 2800mAh.(for reference my cell phone battery is 1700).
I might try it as a charger for the 18650 cells if they were charged independantly, so I could pull a cell out to run my ecig on.

I keep the unprotected cell as a spare, and use a good quality AW cell in it.
Single cell avoids the risks of multiple cells. Also easier to slip in a pocket.
