I'm not doubting the differences in the electrical properties of the batteries. That can easily be shown and proven with various testing instruments, no problem. The problem I have with what you said is that you can HEAR the difference between two different BATTERIES when playing music.It isn't about the music beig listened to it is about how the load os put on the battery in a way it os like compairing a deep cycle to a starting battery the kinetik has thicker plates than the powermasters resulting in a slower transision response belve me or not doesn't mater to me. Just saying the info I had found a while back when I was comparing difrent d31 AGM batterys that's the reason why people will find they can pull higher numbers in spl comps even though the batterys may have the same cca as another or same ah as another. All AGM batteries are not made the same that and ts been tested that kenetiks aren't made equal you can test 5 of the same type of batteries from them and get difrent cca and ah off almost all of them.
"kenetic will be better for long bass hits that it will be drawn apon for prolong periods of time but the power master will be better for kick drum hits and draws that are quick and powerful."
An SPL competition is one thing where there are heavy, long draws on batteries and you have instruments out testing the SPL, current draw, etc. But to actually be able to hear the difference between two similarly spec'd batteries through the dynamics in music? Psychoacoustics. Unless one battery was small and weak in the first place, and the other was fully charged and twice as big, I still call BS.
