One of my problems with "% charging" is if you are not supposed to go below 20%, then you mis-calibrated. Whatever was 20 needs to be zero (0). My amplifier goes all the way to 11. Yours only goes to 10. Meh. I'm not in "Spinal Tap" I don't need to go to 11
. The battery 0-100% should be calculated to optimize total energy thruput on the device. I would like to see a rating as above: 0-100 @ 6000 full cycles. This should be whatever the point is that maximized total energy in/out.
