Lithium battery bank (VE Modules) and Multiplus II

I know this question is bordering not relevant for Victron, but I may not be alone with this issue - and there are so many skilled techies here so I hope you can forgive me.

I just purchased 5x VE modules Samsung SDI 2,08Kwh, modules are configured in 12S cells 42Ah, so the voltage range is between 38,4v-49,2v.

I want to build a bank around 10kWh capacity, so the config 12S5P.

I have a Multiplus II 48/3000 wich I want to use, so the question is the voltage range suitable for the charger section of the Multiplus?

Attached an image of one module

Thanks for your answer,

The individual 42Ah cells are welded together and I suspect messing with that is going to cause more pain and cost more than I would like.

This is why I suggest to give it a try with 12S5P
