Powering the board above 6.0V will permanently damage the >onboard voltage regulator" One cell should be sufficient for powering the Pico. The regulator lower limit is 2.3 V so there is a need for deep discharge protection on the cell. -- Dipl.-Inform(FH) Peter Heitzer, peter.heitzer@rz.uni-regensburg.de
