mosfet max amp is 240 (limited by package ) but can do more for small time period (if i understand all correct )
and vesc with 0.5 miliohm shunt i set 200 motor amps and all ok but in vesc with 1miliohm shunt i set 160 and drv chip is dead (will test more when spare drv chips will come)


Do you have any news on this, artteth? Got also some dead drv chips and I am using 1mOhm shunts.
