I have the x6 charger that reads IR. If i use my normal long (12 inches) charging leads to measure IR I get IR in the mid 40s (45 mOhms) if I use a high quality short leads like I would use in the race car I get closer to ~ 5 mOhms and on some packs down to 3 or 2.5 depending on temperature.

So many things go in to IR, the temp of the battery and the resistance of the cable and connectors, calibrations of the tool your using to measure. we are talking about micro numbers here, my reading of your pack with my tools may be different than your readings of your pack with your tools. you should be looking to make sure your testing the same way every time and the same temp, once you establish a baseline you can track and monitor trends.

to the OP: I would do more testing of other packs that you have a known IR and get your baseline for your testing setup, also have other people test your packs that know their own base line and see what you get and work from there.
