For my project I built a BLDC motor controller.
Now I have to cut of the controller from the battery. A relay is not easy because common my application needs >200Amps
The highside switches I found is the Voltage rating too low. The max Voltage I found was 60V.
Battery voltage is 60V and the max current about 200A.
Also I am afraid of using semiconductors because they like to shoot trough after burning...
