Kind of, but not really. Standard shunt on a INA219 is 100mOhm, i personally use a 7.5 mOhm (75 mV @ 10Amp) shunt at the moment but will switch to a 50 Amp shunt after testing.
So set_calibration_16V_5A, with the ability to chose a custom shunt resistance would be great.
This here looks great, but i don't know where to apply those settings: https://forums.adafruit.com/viewtopic.ph...ml#p879003
