Does anyone know what the internal power checking routines on a Roomba do and how they work? I am thinking they don't look just at the voltage, but may have some way to sense current. ( I am working with a Roomba 500 series base).
I am guessing if it is over 15v? it thinks it is on charge, and below some other voltage 13? it needs to be charged. I am struggling with multiple dead roomba battery packs. If I can feed a fixed voltage through the external unregulated power connector, perhaps I can better manage performance.
