How accurate is the Opus internal resistance test and what is a good resistance versus a bad resistance?
 


Opus resistance test is crap i would say. Its hard to get reliable values unless you know what you doing.

I also have video about another tester:

I test resistance based on charge and discharge at 1A. if they sort that they are good enough.
 
I think it's daromer who did a test where he put pressure on the bottom of the cell and that made a huge difference but having to apply pressure seems crazy.

In the end, I don't test for IR. Low/high IR will surface when I have them sit with a full charge for a couple of weeks. Low IR means high voltage, high IR means low voltage.
