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 !
