Did you use the same resistance for all of the tests, or did you pick different taps for each battery?
No the load is not the same. It can not be the same if the IR of the Cell are not equal. But if it is programed, could be the same.
The tests are with purpously designated devices Load tester with heat extraction and calculas
The devices allow to test the battery performance with algoritm and/or governor controlling the battery figures and change the resistance as per load function programmed.
One example for such a test. (It is a racing battery for Boat 6800 30C, developed over 6600 65C)
On some of battery the loads aplied are bigger then the C-rate to test the strenght of the tabs, or analyse the electrodes after the test.
I have posted the curves for 5000 25C discharged with 150 amps (30C)
One more good project 8000 25C (but in weight limits)
