My Milwaukee is the plug in type (yes they still make them).  I have
power at the tower for the raising winch so battery operation is
not required.  It overheats after a minute or so when the load is
large.  I don't see any solution to that in a drill you can hold
in your hand; its limited by physics.  When the drill is cooling,
I crank by hand.  The drill and I are a tag team :-).  The winch
needs to rest too so it doesn't overheat.
