princeton: No, the motor has inductance becasue of the coils inside (well it would anyway,but it has more inductance becasue of that), so the current wants to keep flowing, and if you just shut off the mosfets, and don't give the current anywhere to go, it will piledrive through the mosfets from drain to source.

1000amp controller total cost in parts would be very similar to total cost of regular 500amp controller. Maybe an extra $20 or so in metal. So in modest bulk, probably $350, but I don't know how well it will work yet. haha.

Optimal number of farads: infinity. But that's not practical.
