The Connect a battery to Portenta H7 – Arduino Help Center tutorial mentions that we should use a Li-po battery with a ACHR-03V-S connector head, but I have not managed to find a charger in the market that could charge a Li-po battery with such a connector head. Does anyone know how I can charge the Li-po battery?
I think the battery side is a three-position, 1.20mm socket (female) with no pin in the middle.
If the portenta is like the Nicla voice then you use some code to enable the onboard charging i.e. connect via usb and then charge from the board HTH
