I've been thinking about simple testing battery internal resistance/voltage under load.
I realized that the oscilloscope have 50ohm impedance high load mode, so as long as we don't burn it its perfect to test IR by just switching the input impedance and comparing.
Is it such a bad/stupid idea to connect a battery directly to oscilloscope probe?
I plan on using zt-702s built-in scope for this.
Constructive criticism is welcome
