Get two AGM 12v trojan batteries wired in series. Get a tripplite inverter/charger made to have 24v dc input.
Now you have ac out with battery backup and a charger, and 24v dc battery out. That's more than you need (due to ups function with ac out) - sounds like a charger on the battery bank with your radios feeding from it with low voltage cutoff is all you need. Has anyone done that?
