Quite frankly CBA and other testing is not remotely close to results myself and others see while running TP packs in F3A applications.
You can quote all the static air testing you want where those performing the tests let the temps soar to rediculously high values....its not realistic in an F3A application. Our packs see a huge amount of forced air cooling through the entire flight...I have rarely ever seen one of my packs go above 50C (122F) post flight. Testing a pack and letting it run at 180F and having a failure is not representative of real world.
Fact is the Prolites are great cells in real world applications, which is where it matters.
To the original posting at hand...my highest cycle pack is sitting about 75 cycles (TP 5300) perfect balance and the same V under load that it had as new....not noticable degredation that I can tell. I have "heard" of others running well over 100 cycles, but ExFokkerFlyer is the only one that I trust has valid #'s

I think a lot of people guess at their cycles! and are way off!
If you have 4 packs of Prolites and claim 200 cycles each you would have needed to flown 800 flights since about June of 2005!
