Nice work. How does this method of evaluating batteries compare to measuring a battery's resistance as found on some chargers?

- MarkusWandel 6y agoHmmm. Resources left on the board are: One Arduino I/O pin (the TX one), one unused relay. That could be used for one of the six channels to decrease the load resistance slightly by splicing in a parallel load resistor. By measuring the voltage drop from momentarily increasing the load, the ESR could be computed, at least roughly, for that one battery position.
