Since it's happened with other Dell battery same kind, I'm reporting it here.

After that, I cannot read it without Disconnect/Connect again.

Have noticed on one battery charging current was 3a, on another 4a, could you try charging same battery with 1a only current and check whether oscillation and interruption occurs?

2.5V

this one; for now you limited to 3 V

@djibattworkshop

sure

@batfix

You have "Ignore SoC, discharge beyond 0%" which is better than setting a minimum stop condition for the cell voltage. Don't forget that you don't have direct access to the cell, you have access only to the battery connector. Between the battery connector and the cells, there is a BMS. The chip part of the BMS decides which is the minimum cell voltage allowed until Discharge FET opens. Even you set 2500mV, if the chip opens the FET when TDA is set at about 2800mV-3000mV what do you do ?

You're right - I forgot I have no access to the chip's parameters and cell(s) as before in my time ...
