This confuses me.. Don't all devices basically get equal shot at the
current? i.e. the output voltage of the charger reflects the voltage of
the batteries at that time and the service devices run off that voltage
too. Unless the charger dies because it tries to output more than it's
actually capable of in continuous operation (Is that what you mean by
current limiting?). But don't most of these systems basically float all
boats on the same rising tide? Most battery banks are capable of
sinking way more current than most chargers can output, so they charge
at 1/10C instead of 1/4C? or 1/x and take a very long time to charge
and don't do a good job of clearing the plates ( wet batteries ) ?

If the batts are fully charged, then your charger/rectifier should be
putting out exactly what the load is needing (plus a tiny bit of
battery leakage current).
If your load picks up, your charger will carry it up to whatever
current limit the charger has.
If you have an extended outage, the batts might suck more than the
charger can put out once the power comes back on. So the best systems
have some form of current limiting to ensure the load gets its current
first and any extra can go to charging the batts.

I’m still learning this stuff.
If I have a 48v battery string and it’s being charged with 10A, and my
load is connected directly to it taking normally 2-7A, the load will
not receive that full 10A current meant to charge the batteries, correct?
Or does it?
