Range: up to 1 micro-meter
Test Set-Up:
Pass high (known) current and measure voltage drop - have known shunt resistors (in the bay) so we can use that to ensure current measurement is accurate
Elec - test takes 10 minutes to do
For measuring resistance in-between pack: measure resistance of pack, and subtract the resistance of the cells - source a measure unit from school labs
To-dos: create a set-up for measuring very-accurate low-voltage readings
As high current as possible
Multimeter
Can be made by firmware though not required
Battery Impedance Meter - more detailed behavior, AC (not needed)
DC determines real-life behaviors whereas AC is a standardize-way of comparing between-cells
