Medium cold in the Mountains in southern Norway, and freezing this morning. Checking how the battery acts during 10 hours from 4 degC to -2 degC this morning. Inside TMX temperature went from 4 degC to -0.7 degC. Battery kept almost constant. Will do this again for lower temperatures during winter. Can go down to -20 degC up here. Will warm up the X to 20 degC, will see how that affect the battery.
