    There aren't 24V they are wired as one big 12V battery and all the meter can see is on big battery. So 50% is just that half gone.

    BUT.

    Always a but, you normally discharge only to 50% so I wonder just what your 50% it telling you ? Common sense is that you are half way to 50% in other words 75% of the battery theoretical capacity.

    50% over all .. It is not 24v but two 12v in parallel ( so result is still 12v but with higher capacity )

    i think you should plug it in to the mains for a couple of days then see what it says.
    if it is a digital control panel like the schaudt ones some of them need to know what the battery capacity is so it can tell you more accurately.
