I see similar sag and low voltage alarm issues, though not quite as extreme, with those same cells in my car when it is cold out. all the cells are in my trunk so I have no way of seeing the mini BMS while driving, so I bought a cellog 8. it records voltage data on 8 cells at a time, and I can move it around until all the Cells have been tested. in my case it showed me that I have a couple of cells that sag to 2.3 volts while the rest stay up around 2.7v. It's a cheap way to get some good data.
