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.

That's what I'm talking about, except we like twice the off grid
capacity... When the shit hits the fan, don't like to be adding
recharging duty to the recovery cycle... So we look for 24V PS's that
can do at least 28 amps...

Many batts don't want you to exceed C/10 or a 10 hour charge. But that
varies by chemistry and manufacturer. Always a good thing to check at
design time.

Personally I do a 24v site. Two 12v 12a batteries. Using WS-12-250-DC.
The Netonix will actually convert from 24v to ~50v inside and then deliver
24v and 48v from that.

And those batteries would be toast at 11V... But more importantly pick
a charger that will recharge your batteries in a reasonable time when
power returns. More than once we have seen power problems return in
bad weather and if your system takes two weeks

As stated before, don't skimp on voltage. Lower voltage setups will
increase the current required for a given wattage proportionally. Lower
volts means you need bigger wires, and the drain on the batteries goes
up as well.
Your 70 watts is almost 6 amps at 12 volts, but only 3 amps at 24

You can still do that. Just charge one 12 batt at a time. Probably fully
charge one in a half hour then switch. Come back the next day.

Our site was a backhaul, an rb750, and an Omni. We had tons of issues with it
until we upgraded to 24volt. Under load it would draw more amperage and things
would suffer. Had another similar site and it’s issues went away after an
upgrade to 24 volt.

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.
