DIY Battery Monitor - ESP32 based
(2023-03-08, 11:38 PM)Techstyle Wrote: 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.

Thanks for the TI link, Jason. I actualy found it earlier and tried to muddle my way through it. In the end, considering the scary- low current capacity of this admirable project, I've decided to literally go in a different direction - using my relative beefy 300A shunt on the low side Wink

I'll be modifiying a Peacefair PZEM-017 to accept the ESP8266 D1 mini which I had originally ordered for this project. In addition, I'll be adding DS18B20s to measure battery temperature. All of this will be processed by SignalK.

The following very detailed articles provide the necessary direction:
