Can I use these or should I try to return?

[Greybeard]

I bought 2 overkill 8s BMS's because my plan was to run 2 24v banks. As it turns out in had a 48v 4k growatt in stock so I bought it and now I'll be running 48v.

Am I correct thinking I can run these two in series to make a 48v? Or should I just go find a 16s unit somewhere?

I'll probably buy a 16s 200a daly for backup as I'm buying doubles of everything
