Expectations for 6 volt batteries
We replaced our two 12V group 24's with two 6 volt golf cart batteries - 220 amp hours. We also have 270 watts of solar, a Trimetric monitor and a Progressive Dynamic 9100 converter with a Charge Wiza...

Specific gravity should be 1.275 fully charged. Might be a little higher (maybe 1.285) for new batteries. Also, like what was said, 12.5V with a load would be quite normal IF the solar isn't doing it's thing (which would be at night). Solar should be keeping the voltage up with light loads. Need to check your solar output voltage at the controller during the day with and without loads.
x2, What controller do you have? For the 6 volt batteries you need a controller that will take the batteries to 14.4+ and hold it there for some period of time during the day to ensure they are fully charged and maintained that way.
We have a PWM charge controller, 20 amp,sold by PAP Solar in Vancouver, BC.
