Has anyone noticed that in PWM mode, when selected less than 4 volts, the battery icon flashes up and down stripes?
I have checked it with full and low charged batteries, to see it does not depend on battery charge. I think it must mean something.
Maybe I didnt check it with discharged enough batteries to appreciate the right moment icon changes, but after watching Busardos review the meaning is clear. Battery icon indicates this way when it is in PWM square wave.
Another thought, according to great Busardos review:
Better to use always PMW mode as it can regulate below battery voltage, and above battery voltage it just turns to DC-DC mode.
