The best way to use IR (in my opinion) is to have a general idea of what they are when the pack is new, and watch out for individual cells that are WAY higher then the others.
Most new packs are like 1-3 (these days) but I've charged some old packs that are like 20-30, but they still work, just not as great as the lower ones. Depends on what plane you're using and for what. Those 20-30 milliohm packs are perfect for lights and rx packs. And who knows, maybe those 5 year old packs that are 20-30 were always 20-30.
It's really good after a crash or you drop one and you see a particular cell twice as much as the others...then you know that cell is going bad.
Does that help?
