Welcome to the forum! I might be able to build a pack for you. I live in Denmark.
Here is some reference of my previous work
But I need to look into if I can get my hand on a decent BMS for the sufficient voltage in time, as I don’t have any on hand at the moment. I’m leaving the country for summer holiday around July 15-20, and only coming back around September 1. So I would need to have everything on hand by around July 10 to finish the pack before I go on summer holiday
