I've never seen a low voltage disconnect on telecom rectifier + float battery setups. It's assumed that for a backbone ISP POP that you will have an auto start generator.
Or that you would rather drain your batteries all the way to dead, damaging them, but keeping the equipment online as long as possible (customer SLAs and hoping the grid power restores itself before the battery string is toast).
