When is the battery empty and when should the mower be switched off?

How do you set up your mowers? I have a 7S2P battery and I'm wondering when the mower should drive home and when it should shut down. Currently, I have the values set to 24.7V and 23.3V.
 
You would have to test at what voltage the motors stop turning.
I think it was just under 24V for the Matrix where they stopped turning.
 
I personaly use 23V to go to station and 22V to shutdown mower and no particular issue with 7S3P battery.
In all case always use a battery with BMS and check that voltage read by firmware is correct.
Try to check your 18650 cell datasheet .
To calculate On 7S simply do 23.3V/7=3.32V so you can stop later 3.0V is often ok for this kind of cell.
And you can go to station and 3.2V for example, so 3.2*7=22.5 Volts.

@Sascha Motor stop turning ?????, normaly they can rotate at less than 20V
 
Yes, I think they stop spinning then, but I'm not sure anymore how many volts that was.
