Last weekend, I had problems with my Speed Passion Reventon Pro switching itself off once I'd brought my car to a standstill after a 5 minute race. When I switched the ESC back on for the first time after this, the speedo would constantly beep and flash the LED's. I cant remember what colour the LED's were flashing though. The only way to stop the ESC from doing this was to disconnect the wires from the batteries. The motor and ESC's temperatures were normal and not excessively hot. Can anyone tell me why my speedo was doing this and how to prevent it doing this in the future.
