This short .pdf shows how to use a DeWalt pack
_without modification_, allowing the use of the stock
charger and stock BMS.

Using the stock charger and BMS seems awesome. With that, you could
make a pack that is:

4.5kWh
156 lbs
45 kW at 10C !!!

That would be an incredibly awesome motorcycle battery pack!

And then I found the bad statistic: cost. 60 batteries at $115 each is
$6900. Ouch; I don't want to spend that much on batteries, even
light-weight awesome batteries. And then you have to add the cost of
chargers.

Yup, it sure is expensive. I know several people who
have purchased an EVs worth of DeWalt packs and have
taken them apart to build a bigger pack. But then
they had to develop their own BMS. There are also
people who have just wanted 2 or 4 packs for a bike or
scooter. I think this is a better solution for them.

I spoke with someone who wouldn't want me to say he
worked for DeWalt... he confirmed that the tool is
"resistively programmed" (meaning there are different
values of resistors in the tool) to tell the battery
pack how much current to allow before a fault. I
believe he said that the "Saw-Zaw" type tool DeWalt
sells puts out the most power. Other than that, I got
more technical information from the link below.

Now that I think of it, I think I was wrong, and it
was their cordless LiIon Circular Saw that draws the
most current.
