I'm kind of new to this stuff, but isn't the C (or Capacity) rating just the amount of current the pack can sustain without damage. To me it has nothing to do with how well the voltage is going to hold, rather how much current it will put out without damage. I have seen some voltage/current charts for some batteries but I haven't seen them listed for 30C and 60C rates.
The ones I have dropped quite a bit. I agree about some over rating and some underrating, but there may be some differences about what is over/ underrating. One engineer may say that at full discharge the cell must not drop past “x” value, another may specify a different value. This industry is fairly new so very few standards have been developed.
