The charge controller has a cut in of 13 volts and a cut out at 14.2 volts. I expected it to be in between those numbers. Not the battery volts(I understand 12.7 is full) but during the charge I expected it to be between those numbers..
Discharged batteries will see a slow rise in voltage to the numbers you expect.
It MAY rise to bulk/absorb charge voltage of 14.8V. It will not cut out but as the battery becomes charged it will drop to float voltage of 13.4V. OK the controller will cut off at night during the multi day charging.
Your small solar system may not be able to reach bulk voltage but it will still be able to charge.
