Low cell voltage

I have a 12V Victron 160ah LiFePO, BMV, MPPT, and Buckboost set up in a campervan. I’m recently seeing low voltage on a single cell in the battery.

The system did a full charge yesterday and now reports an SOC of 62%, with -58 consumed Ah

The MPPT is configured using the preset, and the system has been working for 3 months but clearly something isn’t right at the moment

Any advice to force the battery to equalise or other help would be very welcome

Do a full charge first, and see how the cell voltages are then.

and I'd check the BMV if it doesn't reset to 100% too soon, this can give an incorrect SOC reading.
