Yep my Best Power UPS is the largest that they build that runs off 
13.8 volts it's a 1.4 KVA.
I have a question, How long does the 4 33AH batteries last at what 
ever load that you have connected, and is it a fairly light load? It 
seems that they wouldn't last long with much of a load.

 Any UPS that is big enough to handle the load of a
 repeater is usually powered by 24 volts or more 
 (many 12 volt batteries in series).
 
 The one I just listed uses an internal DC voltage 
 of 48 volts, with all 4 33AH batteries in series.
 
 I agree with you though, the more times you "convert"
 voltage from one level to another decreases efficiency.
 At one of our club sites, we have a bank of 6 "2 volt"
 500AH cells in series, being charged by a commercial
 Staticon unit. The batteries only have to last about
 2 minutes, as there is a HUGE generator that powers
 everything at the site. Lucky I guess :)
