UPDATE: Still working thru this, 14.7 at the charger when in bulk mode, only getting 13.6 at the batteries with a digital meter when the charger is in bulk mode, 13.4 with the shore power disconnected at night without solar input.
I'm thinking there maybe an issue inside the Giggy Box.
Will provide further info whenever I disconnect the batteries, and remove the custom battery box to permit access to the Giggy Box.....
