I think raw voltage measurements on this system are dodgy, since the alternator does not work the same as an alternator from the ‘80s would have. It’s a PWM system, if I remember right, so that makes it difficult.
What the low voltage could be telling you is that the computer determined no charge is needed, because it’s a new battery.
