Picking apart other peoples testing and ignoring the actual math of it all is really just trying to start a war... There are LOTS of numbers out there to support the suggestion that cheaper packs do NOT live up to their C rating and that SOME more expensive packs DO live up to their claimed C rating... there are people out there smarter than you or I doing these tests for NO biased reason other than curiosity.

Using Maxamps as an example of an "expensive" pack is just silly... everyone knows their stuff is overrated and under delivers FOR WHAT IT COSTS (in caps because its an important point)

But, packs like SPC, SMC and ProMatch are all mid priced and, in independent tests, DO provide their claimed C rating.

So, IF you can accept that these packs DO deliver the C rating they claim and IF you can accept that high performance brushless systems can draw 160+ amps and IF you can understand the math in regards to a batteries ability to supply amps based on its C rating and capacity... youd be able to clearly see that yes... high C rated packs (given the C rating is real) DO provide more performance. The question of weather or not the average person can FEEL it is so subjective is worthless to argue.

On the other hand... if you CANT accept the points listed above... theres really no point in anyone posting because minds have been made up long before anyone posted and some just want to argue.

The independent testers I have spoken with all agreed Turnigy and Zippy packs do not deliver their claimed C rating... same goes for Maxamps. So, if the argument is between maxamps and Zippy/turnigy... go with the cheaper option.
