Well, are conventional Lithium ion batteries good enough?   How much more expensive are these?   Would people be willing to pay an extra $50 or $100 to save a pound or two, or to be able to drill an extra 30 holes?

I'm with Del on this one. M-18 9ah battery $199 has 15 EA 18650 batteries @$5 ea. M-18 8ah has 10 EA 21700 batteries @ $9 ea. $149. M-18 12ah has 15 ea 21700 cost $219. This new battery sells for $24 each which would make a 12 or 15 ah battery with 15 EA batteries price point at $500 - $600. I believe 30 extra holes would be a strech with the new battery.

So, looks like theoretically you would get 5000/3500 times as many holes, roughly 50% more.    The cost increase, using the retail price for the cells, would be $300.
