Jakiper battery, cells 6 and 7 voltages reading jump and change erratically

[Aridom82]

I saw the red light of alarm on the battery and when i checked the cell voltages i saw that cells 6 and 7 voltages keep jumping around and changing. Seems that the bms has trouble reading them. Eventually it starts reading them correctly again.
Any idea of what could cause this? These photos of the display have been taken within 15 seconds of each other.

You probably have bad connections on those cells. I would clean the busbars and terminals.
Then put everything back together and make sure the terminals are torqued correctly.
That worked for me when I saw what you are describing.
