The loaded voltage is about 12.5 to 12.8 comparable to what would be in the trunk of a car starting at 13.8 at the battery alternator connection.. including voltage drop... That was the design anyhow... Astron's or eq are some what of a problem as they really do not sag at all.. 13.8 all day all night all nice....
I chose a different route at work and built a battery stack with a trace engineering charge controller float charging the batteries active all the time using a astron or eq as the "charger" source.. The trace engineering controller ( from the solar world) does the charge maintenance etc like no aftermarket tool I have found for eq money....I think it was a Model C40 or C65... maybe a C30 would do... all are different current specs...
