The manual says that fault codes appear in the odometer, anything there when it plays up?
it depends lots on which version of firmware is loaded. The early versions gave you very little indication of what the actual fault was
red battery light on its own usually means the motor controller is running at low voltage limit. I forget what it is for the original firmware.
I *think* it was 108v, which if you're doing a sustained hill climb might make sense
A later version of firmware, which you might have loaded, would light the red battery light if the battery voltage was below 115v for some period of time. Though the red battery light wouldn't then go out until you recharged.
