Is Trinity white carbon really that good, better than anything else on the market?
Do you have any experience with Performa? I have seen couple of people running them at my local track.
I am not sure about new reedy packs, but it seems the older ones use to last really long time if not...
Ir is useful but you can't really tell if the battery is good.
I had one protek battery that showed good ir on both cells, I don't remember the number it was over 4 years ago. But one cell was so bad that had less than 1000 mAh capacity, and lvc would cut very early
