Der maximale Line-Current ist dort mit 120A programmiert. Du kannst in der Programmierung auch bis 150A angeben (mehr lässt die Firmware nicht zu).... und mit etwas Glück kommen dann am Motor 130A an

.
Mit 'nem ND72530 kannst Du in etwa bis 150A Line-Current hoch gehen (450A Phase-Current), mehr gibt der verbaute Akku leider nicht her, da das BMS dann dicht macht.
Thank you for that neat summary.
I was trying to find the basics here. Many threads and posts!
OK, so the 72530 I have bought (not yet fitted) can be set to 150A, from the 120A the original controller is set at, and if it draws more than that then the battery will shut off?
It is the software provided to us that does not allow the higher setting, and even if we did set it to higher, the battery would say 'no'.
Does the battery trip sometimes anyway, if it is close to the battery limit? What is the battery's 'safe' true capacity, and is 150A already stressing its BMS?
Perhaps a more modest 140A, so a nice 15% increase, less resistance in the bridge so perhaps more, and the battery is happy?
I guess the motor and its many windings would be capable of more. When I have done a road test, it does not seem to get hot at full load for a long time.
