Looking for advice on ability to have 2 strings of 5 x 25.6V for a total of 10 in the same system configuration. There are 2 Quattros 8kVA. We have Cerbo GX as part of install.

Smart Lithium 25.6V 10 off in two banks of 5
@Justin Cook - Bay Marine Supply USA Thanks for your time on the phone.
According to the VE.Bus BMS datasheet this configuration is not possible. Datasheet says a maximum of four batteries in series I read this as four 12.8V batteries for a maximum of 16 cells in series, so only two 25.6V batteries in series to make up a 48V system.
Also, datasheet says it's maximum Voltage is 70V.

EDIT:
If, by a "string", you mean a set of five 25.8V batteries in parallel, then yes, that is possible for one VE.Bus BMS. Then you can have the other parallel set with its own VE.Bus BMS.
Afterwhich, you can connect these two sets in parallel to maintain a 25.8V system Voltage.
Thank you . @WKirby The Lynx distribution states up to 32 batteries? Can that be used?
Oh, I think I am misunderstanding what you mean by 2 strings of 5 in parallel. Do you not mean 5 in series?
