During a flight in Northern Ontario, during good weather, my Matrice controller warned me of a 'Compass Malfunction" and that it was 'Switching to IMU backup'.

This happenned during a second flight as I thought it was a flike (and we were flying in VERY remote conditions, so risk was extremely low).

On bringing her in for maintenance, the diagnostic data turned this up (photo attached).

The Matrice only lives in her storage case and is typically stored inside. While we were up north it got cold at night during one evening where she was stored outside (10') but this wasn't cold enough I though to affect anything. During one flight, while 120m up, we recieved a warning that the battery temp dropped below an acceptable level) so we brought her down. The batteries felt normal to the touch when we took them out.

The unit is exactly 1 year old from purchase.

Do let me know what to look for, what may have happenned, and how to repair please.
