Charge relay keeps switching

[K!NG]

Just finished the Ardumower build.

It's configuration:
PCB: v1.3, based on kit Marotronics Q1/2021
Firmware: Azurit v1.0a10
Battery: Ardumower Power Pack 25,2V 5Ah (ASN1286)

Now I am facing an issue when the charger is connected to charge the battery. In that situation the charge relay keeps switching. ~3s ON and 3s Off.

The logging shows this:

Does anyone have an idea what to check ?

Thanks!

Check the battery setting.
The " Battery is fully charged if current is below " can stop the charging too late, Try to put 0 here.
The " charging starts if Voltage is below " try with 24V or less
