Duh! the two batteries are in series. The one with the 12v tap cannot become
more discharged than the one without because the battery without the tap
will charge the one with. Or the one with will discharge the one without
until they are both the same. This is the same thing that happens with
individual cells in a 12v battery. With two 12v batteries in a series one
simply has more cells in a series.

Duhhh, Hay Capt. Neal......
Son, you better go back to your Basic Electrical School, and ask for
a refund of your tuition. You didn't learn a thing, about DC Systems.
The above is total nonsense, and has to basis in FACT. The current in
a series string is the SAME, anywhere in the series string, and limited
by the highest resistance element in that string. No charge will flow
from one cell in a series string to another cell, in that same series
string, and they will NEVER balance themselves out during discharge.
That is what and Equilizing Charge does, and that is deterimental
to the battery cells that have lower internal resistance, as the
Equilizing Charge brings those cells with Higher Resistance up to
full charge. The only reason for doing an Equilizing Charge, is that
it is less detrimental to the total battery to overcharge the good cells,
then it would be to allow the weaker cells to continue to be
undercharged.
Best you stick to navigation, and leave the Blackgang Stuff to the
engineers......
