Build or Buy?

Currently have 48v ~10kwh home brew with Seplos BMS.
I want to double or triple capacity.
What's the most economical these days? Vendors and suggestions appreciated.

There are threads but I'm not seeing recommendations.

Not sure you will get a Recommendation but you will get everyone’s opinion on the matter.

It’s a very subjective thing.

Surely, if you've already built 10kWh DIY battery you know what is involved time and effort wise. So is not working out what is most economical just spending an hour on the interweb checking out prices of cells and BMS to whereever you live, compared to getting a reputable battery rack system delivered to whereever you are?

If I were you, I'd be looking at adding another DIY rack with 280Ah cells to add another 14kWh, using a Seplos BMS again for ease of integrating the two systems together. But, as @Nobodybusiness said, 'it's very subjective'
