Oops! I needed to take into account MOSFETs and DIODES!
Each mosfet/diode can handle 50 amps for a while (maybe 1 minute?) until things heat up too much. But read the datasheet. The mosfet is no problem. It can handle 130 amps continuous (well, it would need some AMAZING heat sinking, thanks ben, and the leads might not like that much).
The diode is rated for Irms = 50 amps, but it's root mean square! So, to be safe, all you have to do is keep both diode and mosfet root mean square current under 50 amps. This allows for higher peak currents in the current limiting software under most circumstances.
So, assuming that you limit Irms to 50 amps for both the mosfets and diodes,
Here's a table of controller current limit:
0% PWM DUTY 500 amp current limit
10% PWM DUTY 527 amp current limit
20% PWM DUTY 559 amp current limit
30% PWM DUTY 598 amp current limit
40% PWM DUTY 645 amp current limit
50% PWM DUTY 707 amp current limit
60% PWM DUTY 645 amp current limit
70% PWM DUTY 598 amp current limit
80% PWM DUTY 559 amp current limit
90% PWM DUTY 527 amp current limit
100% PWM DUTY 500 amp current limit
