New server battery question

[Ennis437]

I currently have 2 SunGold power 48 volt server rack batteries headed my way, my inverters are the SunGold power SP 6500 do I need to do anything to balance the batteries before use? The manual is 0 help on setting up communication cables. I currently have 4 12 volt power queen batteries running in series that I top balanced each battery before instal just wondering if I need to do such a thing with these 2 running in parallel. Thanks

I would find out the max charge voltage of the battery. Charge it, and once fully charged, hold it there for 8 hours. It gives the BMS time to internally balance the cells.
