Badcaps Forums - View Single Post - EBC-B20H 20A 12-72V Lithium Battery capacity tester just bought one

I have read this as well but I do not know how to interpret the results of what the ESR value would mean for battery cell health that you could rely on

I have tried this but I have had mixed results so I do not use this for an evaluation method
