    I did a litlle test today.
    I realized, after reading ypor post that I might not have done this test with a battery sub sero + the blue snowflake.

    We actually have above zero C temps now( warmer than usual), its been around +3 to + 5 C.
    After being more than one day in the garage (+14C) and charged to 70%, I left for work.
    SMT(BMS) reported 79.9kWh as Nominal full pack.( degradation has started just a little I guess :confused: )
    70%, 167Wh and 336km= 80.2 kwh

    When arriving at work:
    62%, 145Wh and 340km = 79.5 kWh

    After the day at work, before starting to move from the above point, no preheat( I think):
    57%, 145wh and 312km= 79.4 kWh
    Battery temp not checked, but somewhere closer to 5C as standing over the day and arriving at about 12C.

    Ive seen the SOC lower other days just by standing over the day earlier.

    At home again,
    47%, 145wh and 260km= 80.2 kwh.

    All readings quite close. Expected variations that comes from the only two value figures in SOC.
