And then what voltage did your capacitors charge to ?  Again, if your
charger is like mine, you're going to get something like 18-20 volts, which
would explain the high current.  Especially when applied to a stopped DC
motor.

4,000 uF is certainly adequate for this, but I wouldn't call it overkill ...
ISTR my 10A bench supply has 50,000 uF and it still has some ripple.
