When I cycle, I look at the 8 volt time, 120 second and 240 second voltage numbers to compare, along with the IR, total discharge time, total mah and average voltage. Basic GFX stuff as well as what the pack looks like on the icharger.

With the mudboss packs, I'd see anywhere from .5 to .7 per cell on the icharger or 1.4 to 1.7 total on the gfx. I'd still be running those now but they're heavy, in the 330 gram range.

I've compared 6500's, 7000's, 8200's and 8400's. These have been R1, SMC, Intellect, EA, Fido as well as some no name brands. Everything but the 7000's were 7.4v packs, with the 7000's being 7.6 packs. All full sized stick packs. In each case, the 6500's always had the lower IR's compared to the other open packs (non mudboss). What Trilerian said makes the most sense to me with the cell configuration and the heat in the larger packs not being as high as the lower mah packs after a cycle, but I always put two cycles on each pack and used the second cycle numbers as the result. They were all done at the same temperature, other than what they gained due to the cycle. When I'd cycle the packs, I'd cycle one pack once, then a different pack allowing the first to rest until the second pack was done then put the second cycle on the first pack.

Overall, just trying to learn more. As I said in the original post, the fact that the battery manufacturers are starting to post the cell configurations with the other battery information peaked my curiosity.
