We actually have equipment that has a board with it that does serial communication with a watchdog that also does AC and DC input to 18volt output. Sweet board, but there are issues with the serial communication, the price is too high, and it's proprietary so it will only work with this certain manufacturer's equipment. We need this to install equipment on power poles and give battery backup while keeping our physical footprint down as small as possible. Hate to put a UPS on a power / light pole.

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?
