IIRC, the limiting factor in the 500A controller is more the diodes then the fets. I would say upgrade the diodes and you can probably push it to 700A as long as the controller stays cool.

In theory, the limit is just bus caps and PFC and output transistor. The voltage sense circuit can be adjusted with different resistor values. The current sensor is good to 100A.

You should always use a pre-charge resistor with any voltage. 100 ohms is a Perry good value for any voltage pack. You will want already a 10 watt one but 20 would be better.
