For round numbers, pretend the controller is using 12 mosfets to do 600A output.

Instead of hooking 600A of batteries up to a single bank of mosfets, break the batteries up into 6 isolated packs of 100A. Hook each 100A pack of batteries up to a separate bank of mosfets. Evenly stagger the triggering of each of the six banks of mosfets. So each bank only gets 100A, and you're still outputting the full 600A (max). Did that make sense?
