Looking at the example circuit, it seems like the chip's power lines are hardwired to the battery cell. monitored-battery does not seem useful today, as we don't have any information about writing values onto the chip :/ And I'm not willing to experiment with that! :P Konrad > > Best regards, > Krzysztof >
