I have Fiido t1 20ah battery found melted phase wires at controller so I've upgraded display, 866 controller replaced motor. found bad key switch both terminals loose turning inside switch arcing and getting hot. Lucky for me I got a replacement bike so used spare and it had a improved switch with square shanks to stop terminals from working loose. So not an isolated problem. Has anyone else seen this?
