here are some graphs 
Cell Voltage is at 3.5V, Diff is below 10mV, ChargeVoltageLimit value was changing somehow, but never went to 3.75 :-( |

done Select which version you want to install and enter the corresponding number [1]: 6 --2024-04-16 16:34:20-- https://github.com/mr-manuel/venus-os_dbus-serialbattery/archive/refs/heads/master.zip and the new version got started in debug mode I will watch now if the behaviour is changing and will report here. thanks a lot for the support |

unfortunatley the bevaviour has not changed usng the nightly build from 04-16 
no error, no reboot in log files, which in debug moede only seem to last for approx five minutes any other info I could provide? |

missed one diagram - cell difference is below 0.010 for more than 900 seconds |

Below Discharge Current Limit there are other very relevant informations, if you enabled DEBUG correctly. |

Hi Manuel, 
I hope this is now more useful for you. cheers |

Yes, in this screenshot the cell voltage difference is What if you change CELL_VOLTAGE_DIFF_KEEP_MAX_VOLTAGE_UNTIL = 0.010
CELL_VOLTAGE_DIFF_KEEP_MAX_VOLTAGE_TIME_RESTART = 0.013
CELL_VOLTAGE_DIFF_TO_RESET_VOLTAGE_LIMIT = 0.080to CELL_VOLTAGE_DIFF_KEEP_MAX_VOLTAGE_UNTIL = 0.015
CELL_VOLTAGE_DIFF_KEEP_MAX_VOLTAGE_TIME_RESTART = 0.025
CELL_VOLTAGE_DIFF_TO_RESET_VOLTAGE_LIMIT = 0.080It seems that this is the problem. |

Yes, in this screenshot the cell voltage difference is
0.010V, which is very close on0.013V.What if you change
to
It seems that this is the problem.
