One thing I found interesting is that this guy makes the same assertion as the BattleBorn CEO did in Will's
interview with him (that low temperature is more of a soft limit relative to C rate than a hard limit).

If I understand the chart correctly, wear and tear on the battery is roughly equal at 1C @ 10°C, 0.5C @ 0°C, 0.25C @ -10°C, or 0.1C @ -20°C
It would be interesting to see how the chart would look beginning with a more modest charge rate at a more comfortable temperature (say 0.5C @ 20°C) or beginning with the standard testing profile which I believe is 0.2C @ 25°C
