Only reason I bring it up because if true that might affect the readings? Only thing I can think of is maybe some batteries have bad IR readings at low current tests but at high currents the IR is very good. I am aware that lipo batteries in general do have better IR when they warm up but maybe some do this a lot more than others because of the mixture?
From what Wayne Giles has told me a few times, some LiPos seem to be constructed to have a better "heat coefficient" where they can tolerate, or are purposely designed to withsdand higher discharge when warm than another battery warmed to the same temp - or something to that affect.
