<div dir="ltr">The Dewalt 20v 6ah pack uses 21700 cells as well. Expensive, but there is a noticeable improvement for SOME tools. The DCF-900 storm-bringer 1/2 impact driver benefits from the extra current.

One of the reasons the old nicad tools are cheap is because they suck,<br>
compared to modern tools of any brand, even cheap ones. They're<br>
designed around the power output of the battery pack, and the nicad or<br>
NiMH batteries didn't provide much power. This is perfectly fine for<br>
things that don't draw much power, but it's pretty limiting for<br>
anything that drills, saws, or grinds. it's also why cordless saws<br>
used to be so incredibly gutless, but there are now cordless table<br>
saws that work as well as most jobsite corded table saws.<br>
<br>
Discharge current of a sub-c nicad (the cell in most nicad tool<br>
battery packs) is somewhere around 2 to 4 A; the lithium cells used<br>
in modern tools can produce 10 to 30A depending on the particular<br>
cells in the pack; milwaukee high output packs[1] (which use<br>
physically larger 21700 cells, instead of 18650 in their other packs,<br>
and commonly used by everyone else) can go even higher. That means<br>
18V lithium packs with three sets of cells in parallel have more<br>
potential power output than a 15A 120V receptacle, and tools with a<br>
pair of batteries (common for miter and table saws) are quite capable<br>
of taking advantage of that.<br>
<br>
[1] pretty sure other brands have 21700 packs, too.<br>
