Are there any recommendations for 48V already assembled battery？

[Rain@]

For those who have ordered 48V finished batteries, could you please recommend some brands and models?
How about "Tewaycell 48V 300Ah 15Kwh All-in-one Mobile ESS Built-in Hybrid Inverter"?

It's really local market specific and I'm not sure if we have a lot of German knowledge here. You could add In Europe to the title to get more specific answers.
