Early stage of development for phones.

 

Thoughts on replacing lithium batteries in augers?

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?

Without a doubt!

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.
