Default internal resistance, imax b6 v2

i just got myself a imax b6 v2.



the charger can measure the internal resistance of the cells. however the reading is very different than manually measuring it.





i took a few measurements with the b6 v2 (they're always a bit different with the same battery)



then, i measured the internal resistance manually using a 1ohm resistor and ohm's law and kirchhoff law.



what's your experience guys? can the b6 v2 mesure internal resistance of cells accuratly?

I don't trust my charger to measure IR (iCharger (Junsi) 306B and 308Duo)
I bought the "ESR/IR Mark II meter" and that is considered to be the "Gold Standard" for measuring ESR and IR and will also give an estimate of the pack's "true" C-Rating
Progressive RC has them.

But, you can read more about them here:

Sure, the numbers are not going to be exact/completely accurate. The internal resistance readings on chargers should only be used as a tool to see how cells are aging.
