It was between 40-48F for this trip.

Started looking around but it seems 5C or 41F shouldn't impact SOC too much (1-3%). It's at -5C where capacity starts to be seriously impacted.

Moreover, the same trend can be also presented during discharging of the cell at subzero temperatures, where the cell capacity reduces to 92%, 85% and 82% of the cell’s depth of discharge (DOD) at -5 °C, -10 °C and -15 °C respectively
