So I was coming home after writing this post and at the bottom of the same hill the maintenance light comes on like clockwork. I'd just coasted down this big long hill, hitting 90kph, but I didn't use any regen this time. Then got to the bottom and started winding on throttle to go up the other side, light comes on immediately. Sigh. Same place 3 times in a row pretty much.
Is there some issue with coasting fast down hills that I should know about?
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.

oh, maintenance light usually means a glitch in the CAN bus, or even the motor position sensor
for that sort of thing, unless something stops working, don't worry about it
Error codes aren't stored anywhere. If you're keen to find out what the error is, the only way is to ride around with a laptop connected logging the CAN data.

I still had 5 bars of battery left at the time (like >138V?) and the light came on at the bottom of the hill after coasting down, before the significant climb back up the other side. Where would the low voltage come from if the bike had been essentially at idle for >1min?
Still waiting on the CAN->USB cable to arrive... any day now... any day...

Where the charger is present, the dash uses the SOC reported by the charger to drive the fuel guage.
The fuel gauge can be simultaneously full, and the motor controller in low voltage limit
Though if the red light came on before you started drawing significant amounts of power, that would seem unlikely
Was the red battery light persistent? or did it turn off again?

It did turn off again once I crested the top of the hill and went a little further on the flat.
So I had an epiphany on the way home. That random range figure that I thought was busted always hangs around between 130 and 146 km... wait... oh... ooooHHHHHH. That's the pack voltage!!! So I must have a later firmware. Maybe already the dugass or something. Coming back to the warning lights. Now that I have the pack volts, I tracked that over the big down and up hill and it got down to 129 at the lowest. No lights came on.
