nmc batteries to replace first lead acid expired

spacebass

After dreadful experience on Aliexpress trying to buy cheap life4po batteries (Ali express on their part do seem to be refunding the money ok after 10 weeks 8 weeks non shipment) I have decided to buy in Thailand where I live and go for quality.

The question is do I go for 2 x 8 string in parallel of Samsung sdi NMC 94 ah 3.7v or 1 string x 8 Catl or Sunwoda 246ah 3.7v. Obviously trying to get to 24 volts system.
I strongly prefer the Samsung option as these batteries seem to be true industrial quality and have more cycles than the average nmc and are used in BMW electric cars !!
