These are quite common in 18V cordless tool packs where there is a small version with only 5 cells (1P). 

If you are working all day with the tool overhead (like drywall on the ceiling), then I'd want the battery to be as light as possible, even if it meant that I needed several packs to keep one runnable at any given time (with several chargers topping off the stand-by's). 2000-mAh is short running time, but it is a small price to pay to have high amps in a small package.

The 2P / 10-cell 18V packs often have 30Q cells, since 2P of the 15A cells can provide 30A, so...twice the weight provides three times the run time.
