If I haven't used the K2 for a few days, it sometimes falls back to the default settings.
It doesn't matter which version of the app I am using.
The battery voltage of the motorcycle is not a problem, it is always good. I also have the latest version of the power supply, with blue LED. Re-flashing the software does not affect the problem either.
But could it be that the backup battery (if any) in the K2 is starting to go bad?
The serial number of the K2 starts with INNOK21806xxxxx. Is it true that the K2 was produced in 2018? It could indeed be that the backup battery is starting to go bad. When I look at the picture of the pcb board, replacing the backup battery shouldn't be a problem.
At least if the backup battery is what I can find on the pcb board, see also the attached photo. Is this backup battery available separately? If so, how can I get this backup battery? I have experience with smd soldering and can therefore replace it myself.
