Additional con:

  • In 1x26650 configuration, the driver sometimes works normally, and sometimes blinks, then shuts off. I was testing with a KeepPower 26650 15A. My guess is that when the driver first receives power, it tries to identify the battery configuration (1 or 2 battery). And it sometimes misidentifies the single battery as a two battery configuration. This explains why some of the review videos I saw show the SC04 running in single battery mode.
