opinions about batteries....

little update, the IR of the firs pack kept falling but the second pack shot up right at the end at the end of charge they were 10 and 17milliohms, so I guess i can tell which was the low one now, although both seemed to have plenty of punch again for bashing, (no lap times as these are 3 year old tech budget backs and as such I wouldnt be raceing them even if they were brand new). They were fully balanced by the end of charge (about an hour) this time, so from that viewpoint at least they are improving.

Did you take those IR readings through the charge leads, or the balance leads? You will get better results if you go by balance leads, that's how most results are retrieved, but that is cell performance, and not pack performance. Real world results should be read as pack performance as that is all that matters for performance... on the other hand, the lower the actual cell IR, the lower the pack temps will be. That is good, and to be expected from a pack that the IR goes down after some cycles when it hasn't been used in awhile.

My G3 packs went from ~15mohm down to whatever i said before... 5mohm? When new 3 years ago they were 3mohm.
