That is odd. I have no idea why it would get so hot unless the
current passing it was significant. This was a schottky or a power
diode right, not a zener? Most zeners will not take the current.

The problem isn't that you'll completely discharge the part of the bank
you're pulling 12v off of, but rather if you discharge the bank unevenly
and charge the entire bank in series then you're either overcharging the
part you're not pulling 12v off of in order to properly charge the part you

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 with

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.

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

~12v should be OK by specs, but I've never heard of anyone doing such a

Just be aware that 24v and 12v batteries have a higher voltage for charging.

I only have the one NSM5 to connect, I could hook this up to the parallel

What voltage were the batteries spitting out? They charge at 27v but
without a charger put out much closer to 24v until they begin discharging.
If it fried the radio I would first think that it was connected wrong, not
that the voltage was too high.

Charger isn't going to spit out 24v for batteries that need charged, it's

Yes you will. The batteries will probably be around 27v which Ubnt won't
