INA3221 as BMS wiring

Hey!
I have an ESP32 I’m flashing with Arduino IDE and I’m connecting a breakout board to it, so I thought posting here is sound.

My goal is to monitor the voltage of each cell through the balance leads in my 3S battery pack using the 3-channel INA3221 breakout board. I figured 3 channels would read 3 cells. Only have basic EE on my belt at the moment. I’m a bit confused on wiring, can anyone show me how I should wire the board to battery? 4321 leads are what I need to read from the ESP32.

Thanks!!

As far as I know, INA3221 cannot be used for monitoring cell voltage.

Well since its a high side current and voltage sensor, it obviously can be used to monitor a single cell's voltage.

chetan06soni might be confused with the chip itself, and the boards that are sold on ebay.
Those boards have the three shunts all connected together.
This recent post tries to "fix" that (did not read all of it).
