BEFM (direct drive motor) higher than battery voltage.

So, let's say my max speed when BEFM equals battery voltage is 50 kmh. Let's say my battery pack is 24v (it actually is).
I bomb down a hill, hit 51 kmh and continue accelerating. What is going to happen?

Endless down a hill makes endless BEFM. Dump load is the solution. A high wattage low ohms resistor should be activated when the voltage rises to dangerous values.
