Correct: I chose 2.45 per cell.
If the resistance is 0.1 ohms and the current is 0.1A the voltage drop would be .01V correct? Which would mean I would only be seeing 3mV difference at the analog pins which is probably extrodinarily useless... But thanks for the heads up! I wasn't thinking of that being an issue.
So what would I expect the voltage drop to be if I move the current sense resistor the other other side of the mosfet (source path)?
