Looking to implement a back up power system for my seven XPR 8400 repeaters.
Wondering what the most reliable, lowest maintenance method would be. Cost is a factor too.
Obviously, I could install a bank of seven lead acid batteries using the factory connection and the repeater's internal trickle charger. That's a lot of batteries though, and constant trickle charge might not be the best for the service life of the batteries. Furthermore, there is no way to monitor the condition of the battery. I would like to at least figure out some sort of isolator circuit so I could use one battery to back-up multiple repeaters.
I could use some UPS's, but it seems a little clunky and inefficient to use an AC UPS to power a AC to DC power supply, but maybe this is a fair trade off in terms of maintenance.
I've also got a pre-selector that also would need to be backed-up, but that is low enough draw I'm sure I could piggy back it off whatever I decide to use for the repeaters.
