hi you mean both the UPS in PRS(parallel redundancy systen)
mode.then u have to connect the battery back to each UPS
separately.untill unless we are using as single sourse we
should not connect the both possitive terminals of Battery
bank connection in a common bus bar.if any one UPS failed
and EB power also goes off the entire load will be shifted
to single UPS which is working good condition also the
Battery bank which belongs to that battery bank only
support to the load.
remember in PRS mode output only paraled not input sources
(AC mains and battery back up)
