The issues is not current as much a voltage headroom. If you are
running a 12 volt system which quickly drops to 12 volts when the power
quits, and your radios quit working at 11 volts, you will not have as
much time as if you were running a 24 volt system and the radios quit
working at 11 volts.

If you had a couple of < 10 watt devices, I don't see how you'd have an
issue with too much current.

I would never build a 12 volt site if there was any way to avoid it.

Don’t skimp by going with the lower voltage. You will run into an
amperage issues pretty quickly. Seen a 12-13 volt site with 1
backhaul and an omni run into amperage issues within a week. Voltage
is fine, just way too much amperage. It’s not worth the headache.

Hello all,
We're looking to build our first DC power site for small MicroPops
and I see two options after reviewing the WISPA archives.
The first option would be the the SDR-240-24 and DR-UPS40 with Two
12v batteries powering a Netonix DC switch.
The second option we were looking at is just doing the AD-155A with
one 12v battery but I see the charging current is only 0.5 amps and
voltage is only 13.3V which is not an optimal float voltage.
My question is, to keep cost down, would we be OK going the AD-155A
route with the slightly lower float voltage with a 35ah battery?
We're ok with the battery taking longer to charge but I'm just most
worried if the 13.3V will wreck the battery or not.
Thanks all
