Qualifying info: If you don't want/need any features like temperature
compensation or low voltage disconnect, then all you need is a power
supply that can be adjusted to your float voltage, then you wire the
batteries and load in parallel.

You don’t need two power supplies. Just pick the power supply that
has enough current to both power the radios and supply a healthy
recharge current right after a power outage to the radios.

Subject: [AFMUG] DC Power Site
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
