One blunder I once made was to let the battery run down.

Context: Upgrade appeared to have gone well, but I got an error message. This turned out to
be a hardware fault on the K3, but that's another story. At the time, I thought it was firmware,
so I wanted to upload again from a different computer. It was much more convenient to do it on
battery. The K3 powered on, showing MCU LD / blinking TX, but the K3 utility was unable to talk
to the radio.

It took some frantic correspondence with support before I thought about checking the battery
voltage - which turned out be about 8 V !

Embarassing.
