Bluetti Charger 1 (not working) Part 3

I stayed in the video. This is the third update for my Bluetti Charger one unit that came to me about a month ago. It's been nothing but an absolute nightmare. Tonight was the first night I could get it set up stable where it wouldn't reboot every 2 to 5 seconds... The problem is I needed to drop the voltage down to 20 from the advertised 56. If anyone is interested, I am using 8 gauge wire, that's suitable for a house. Any output cables are the Bluetti cables. I'm also hooking this up to a 2024 Ram ProMaster 2500. Power should not be an issue.
