$16.25 per Ah is still pricey. If you specifically need two now, it's an okay price.

These use premium 21700 cells which allow it to be much more compact and powerful than the other 4.0 ah battery that's currently available. Next best thing to the powerstacks.

Solid deal IMHO if you need some batteries for tools. Good deal if you keep a couple with the tools and throw the extras on a charger as you're bombing around the jobs.
