I’ve just finished soldering and wiring up the perun v3 optical mosfet as per the instructions, and used the 25amp fuse. I get to the calibration stage, pulled the trigger until the beep stopped as per the instructions, then pulled the trigger again and the fuse blew. So i put in the 40amp fuse, then as i connected the battery the fuse blew immediately. Can anyone tell based on this what i have done wrong?
battery is a nanotech 6000mah 25-50c, 11.1v with xt90 connector.
