Charging overtemp at 75C seems high even if within spec. Since the release is 55 I would drop it to 60C
Undertemp seems low at -10C as most specs I read 0C would be minimum for charging. I have mine at 2C and release at 5C.
I don't like pressing the temperature specs too hard. Unless this is a special application that needs it.
Charging voltages are fine. I run mine a bit lower but again it depends on usage.
