No proof? I've posted links to credible sources. You're just shooting down everything I say without backing it up with legitimate facts.
As for the quality of the battery/manufacturing process, who knows really? How are you supposed to prove that??? I'm trying to focus on what we do know and have proven to have a positive effect.
How do you know the charger doesn't use a CC/CV charge algorithm? Seems to me that it does considering how much longer it takes to finish charging the last 10-20%, based on the status light on the battery. If what you're suggesting were true, it would take the same amount of time for each of the charge lights to blink before reaching a full charge. From my experience, a P3 battery at 50% charge takes only 10 minutes to charge up to 3 bars, and then another 30-35 minutes to full once the last charge light begins to flash. This can be confirmed by a significant drop in temp on the charger while it finishes with a CV charge algorithm.
If the batteries did not have a high enough C-rating for the application, there would be a more significant voltage drop at full throttle than what I've seen. Everything is within normal limits based on the voltage drop under full throttle load.
I have one P3 battery with 15 cycles on it and it will actually stay balanced to within .01v even at full throttle. My other battery has 7 cycles on it and all of the cells stay within .03v of each other at full throttle. It was more like .05v on the first cycle. While this change doesn't sound like much at all, it goes to show how the internal resistance of the cells is dropping and equalizing. The break in procedure helps this process along by taking it easy on the battery until the cells' internal resistance is within 10% of each other. Ignoring this process will instead increase the cells' internal resistance, causing imbalanced cells to magnify in severity under load until the finally lose enough capacity that they begin to effect flight time and performance.
