For two GC2 batteries in series fully charged “Open” circuit will read 12.73 volts

Buying another converter or using an external battery charger will not yield any better results...

See battery charge table... from Trojan website...

The stock 3 stage WFCO will do as good as any regarding charge rate, charge times, etc... you won’t see over 12.7 volts when just in battery power

You will however see 13.4 to 13.8 when hooked to a 120 VAC source and converter is running.

The plates in the GC2 series battery are much more robust than typical flooded cell RV batteries
