RV Battery bank advise or opinions

I got 280ah Lishen and they are good so far. Looked brand new when I got them, QR codes clean etc.

Buddy of mine ordered from same source and they only had the 310s. 310s came in swollen and QR codes hidden by black top cover tape stuff. He peeled it off and QR code scratched off. These sources are middlemen and really should have better QC. I think the factory switched up on the suppliers. So for now I am giving the supplier the benefit of the doubt and seeing what they do to make it right.

I'm the buddy who got the dodgy cells. They haven't done anything to make it right so I'm not affording them the benefit of the doubt. If anyone cares to know what it's like to deal with them when there is a problem, here's my experience with them

Deligreen 310Ah cells SCAM

Warning: disgruntled customer who only registered on the Forum to warn others about supplier (and do a little bitching in the process). This is the outcome of my order from Deligreen (Changsha Deligreen Power Co on Alibaba): A couple of weeks ago I put in an order with Deligreen through...

Please note as this is an ongoing issue there is no outcome to post of yet and I will instead update it as the situation evolves.

I ended using (20) 280 from Amy for the RV. I bought the 310 just to test and play with them.

The PEX lines across the top scare me. But I guess if you ever had a electrical fire they would melt and help control it

That's a superb installation, better than what I see on premium yards built sailing yachts!

This I doubt. While this is a fantastic RV install and the OP has done a really nice job I see several things that are against the ABYC.
