Error "A0" is not an error.
Cause
If your scooter displays "A0" and isn't charging anymore it's because your scooter is fully charged.
The "A" is the equivalent of "10" in hexadecimal, so you have 10 0 or 100% charged.
You likely installed firmware on your scooter with "show battery percentage while idle" enabled.
Fix
There is nothing you need to do as this isn't an issue.
It just means your scooter is fully charged.
If it bothers you you can flash stock firmware to the BLE and DRV/ESC to remove this functionality.
