That supply has battery revert and will charge a 28v battery and the CPS has a couple of options for batteries. I don't have the software running to see but I think its lead acid or AGM type. Not sure what the harness P/N is but they show up on eBay for reasonable prices. If the fan intake gets dusty do not try to clean the dust off while the PS is running. When the fans inhale the dust the PS can fail and I've seen this first hand.?
