Hi all.
I try to measure how may energy a battery has stored, discharging them to a resistive load and measure current and voltage using INA260.
My problem is the following:
During the discharge, the output in my raspberry pi3 python is 1,66Amp which could be correct.
But in the same time I measure 12 millivolt between terminals I+ and I- to my adafruit ina 260 board and, if the resistence is 2 milliohm, the current must be 6.15Amp.
I have this 3.7 factor.
Could be the INA260 resistence 7milliohm?
Where I'm wrong?
Thanks.
INA260 mesaure less current=
