Title: Zero SR/S Lowest_cell_voltage_mv as low as 2100
Post by: ms_smart on July 26, 2023, 10:26:12 PM

Reading through my generated logs from OBD2 I realized, that from time to time I get a significant imbalance of cells with an average mv of 4000 and Lowest_cell_voltage_mv as low as 2100. This year I see this far more often than before (may be once a week). The chart shows Lowest_cell_voltage_mv over time.
Is this something I should be concerned of?

These cells should basically NEVER dip below 3.0vdc and there are safeguards in place to prevent them from doing so. I'd be willing to bet this is some sort of false reading.

Thanks!!! This was also my thinking. I just wanted to double-check:) Looks like reading this sort of data from OBD2 (lowest_cell_voltage_mv, pack_capacity_ah) is kind of pointless since you can't trust the data.
