I don't quite understand what battery 1 and battery 2 means. The Go Power or any charge controller will only show the voltage and amps of the battery or batteries it is connected to. So if battery 1 and 2 are connected together to form a battery bank then it will tell you the voltage of both together and the total current for both. If it is only connected to battery 1 then it will tell you the voltage and current of battery 1.
BTW I have the 10A Go Power controller. It is a very nice controller but it is a pulse width modulation (PWM) controller. These are less efficient than maximum power point (MPPT) controllers and can only be used with solar panels wired in parallel, not in series. If yours is an OEM installation then they were certainly wired in parallel.
