The piece from Jeff is quite correct when the system is fed by one charge source
only and I was going to point out the subtle but substantial difference, as Ed
has done here, with the twin 12V alternator arrangement; although entirely alien
to us here and I cannot think of one commercial or military vehicle this end
which uses such a system. Apart from being able to handle imbalanced loads I
cannot understand why such complexity is designed-in in the first place.
Its not just a case of discharging one battery of the 24V bank, you can envision
this with just one of the older style batteries having inter-cell lead links on
the outside. Here it is quite possible to tap one cell for instance (should you
want a nominal 2V source) and again destroy that cell and thus the other 5 by
the means previously described.
