3.41A at tail (bad dmm*)
I dont have any resistors that can handle much power.
Is there a way to test resistance with current draw and voltage?
I searched up some guy who did the test but his explanation still confuses me.

Second method
With this method both measurements are made with a load on the battery, this makes it possible to measure the resistance closer to the actual working point.
The formula to calculate resistance is this.
Note: measurement 1 is the high resistance, i.e. low current measurement.
current1 = voltage1 / resistance1
current2 = voltage2 / resistance2
Resistance = (voltage1 - voltage2) / (current2 - current1)”
I am not sure what do do with resistance1 and 2… where do I find these values?
For the first method, I think I could take apart a computer PSU to find some fat resistors in there. What value is a good value for this test?
I got so many 18650 I want to test!
