Hi,

 

I have a pi4 with a PICAN-M - NMEA 0183 & NMEA 2000 HAT, where the power is coming from the CAN bus,

 

So here is the question , If i wanted to add the UPS HAT, would it be able to charge the battery without the external power supply ?

 

Many thanks

The Raspberry Pi UPS HAT charges the battery through the USB port on the shield.  It cannot charge the battery via GPIO.
