Sir I have purchased this module but when I tested the same 18650 cell Everytime after charging it full then it showed wrong reading of the same cell.
1st time reading was :168mah
2nd time 95 mAh
3rd time 125 mAh
4th time 76 mAh
Why it showed wrong reading for the same cell as I charged it Everytime full for capacity testing.

Sand or grind down the metal see if that helps.

That's a great idea, I'll try that and let you know

I don't think it give accurate internal capacity
