It just dawned on me that I may have been barking up the wrong tree
I only have the one NSM5 to connect, I could hook this up to the parallel
segment of my battery bank and get only 12v while the rest of the
installation that's connected in series gets 24v. Do you think this will
work? Don't
~12v should be OK by specs, but I've never heard of anyone doing such a
low voltage to a Ubnt device. Not sure if no ones tried it or it just
ended quickly in failure.
Just be aware that 24v and 12v batteries have a higher voltage for charging.

I've had installations like this. Its best to move the radio periodically if
you are draining the batteries.

I have done this at home with a Pico M2HP. My setup has two 60w 12v solar
panels connected to a charge controller with 2 12v 55AH AGM batteries in
parallel. The Pico is connected to the load output of the charge
controller with a DC input POE injector that I bought from Amazon for
about $10.
My two cents: If you discharge part of your battery bank unevenly (pull off
just half of your 24v bank to get 12v for some loads) you will have trouble
with part of the bank getting over charged and part of the bank not getting
charged enough. If you were charging the bank with an AC charger that
I have a PS2 wired to the 12 starting battery of a generator which starts
and stops a few times a day with no issues. The PS2 doesn't even reset when
the gen starts and the battery pulls down to around 8~9 volts while the
starter is cranking. When the gen runs the batt voltage goes to ~14.6.

Why not run the NSM5 on 24v? Just add a diode or two to the + side,
the 1v drop on them will protect the NSM from
the charge voltage of the bank. $2 fix

I tried that method. Diode got hotter than hell. Burnt right through the
insulation I covered it with (and since it was bent the jacket came right
off).

hehe. well now you know why Rectifiers.. (large diodes) have
heatsinks on them

Mine doesn't. Only doing about 25 watts though.

Where did you put that diode? I have done this and at the low power
that is needed they do not get noticeably warm at all.

Thanks Greg,
I can see how putting load on just one part of the battery bank could cause
issues but this load is quite small compared to the total battery capacity.
I will be putting only 8w on two 150Ah 12v batteries (3600Wh total
capacity). It would take 400 hours to deplete the battery bank
