12.78v predicted. Pretty close given likely error in hydrometer and volt meter. Even more so if it had settled slightly at 24 hours.
I know you didn't ask but I use a Victron battery monitor for voltage (does other stuff), it uses a shunt (like the Trimetric), and a Freas hydrometer which I understand to be pretty accurate.
I'm using three shunt meters as well - a watts up and two turnigies. They are not quite as good because there is 3 inches of wire between the battery and shunt vs the cool on post shunt a lot of you use, but both seem pretty accurate. I desoldered the shunt on one of my watts up with too much transient current. I am thinking of getting a larger one and remote mounting it at the battery post. They have directions on how to do this on their web site.
