AP9211 Battery Protection Circuit, Datasheet suggests shorting the negative terminal of the Battery to ground
If you just erase the GND symbol in the AP9211 schematic you get the DW01A circuit.
In other words, the GND symbol in the AP9211 diagram just indicates where the negative terminal of the battery goes - nothing more. The ground for the circuit powered by the battery is &quot;P-&quot; in the AP9211 schematic and labelled &quot;BATT-&quot; in the DW01A schematic.
