the INA219 is a high side (positive side) DC current sensor
Ah, I see. However, I wonder if this might be a bit of a conundrum for me; my battery management system requires the shunt to be on the negative side. I had planned to use the same shunt.
Are you able to say how the other sensor which you had mentioned must be wired into this system if it were on the low side?
you could use the INA219 on the low side, you just wouldn't get the battery voltage. I believe that INA226 can grab the voltage as well as getting low side current sensing but do not have experience with it

I just put up a second video on the subject showing the NMEA2000 integration, and getting into more details about the board preparation and assy.
