Piper Driver:
Agreed - I've been thinking that the only way to reproduce the fault would be
to build a test rig with battery, charger and associated kit, then put it through
test cycles that simulate actual operation and beyond. Ideally, put it all in an
environmental test chamber to allow temperature cycling as part of the process.
This would perhaps be faster than flying the a/c
Perhaps they have this already, but the lack of info after nearly a month suggests
that the problem is far from obvious. It's starting to look increasingly likely that
some operation at the corners of the battery / charger spec may be triggering a
software bug, or battery management hardware running beyond design limits...
