75v/100v dual ubox fire


Ok, so it was probably running something around 70-75 bat and 90A motor per side… But it was like that for about 3 months with no issues and some really hard riding… This time I started ripping up a hill and about 50 feet in the board cut out and then the wheels turned like they were stuck in mud… It wasn’t a normal fault… What should I look for in this autopsy?
