Hi!
I have a generic 72v 35A controller.I have stress tested it a lot when I first got it,and it ran fine without any issues(this was around a month ago).Yesterday I was riding on flat road with medium throttle until it overheated so much that I almost burned my hand when I touched to check.The phase wires were also really hot but only from the controller side until the yellow box (where the controller and motor phase wire ends are screwed together).When it overheats it cuts the throttle
When I take the cover off after it has overheated,just the 2 80v capacitors are really really hot and everything else is cool.
So, is it worth replacing the capacitors for some beefier ones or this is unfixable now?
When my batteries are fully charged they are 84v so I suppose the caps are really struggling,but until yesterday it worked without any issues even when I was stressing it for good.
