Has anyone heard of these batteries?

I can get them in Canada. But if it sounds too good it's probably true. Zero ratings or reviews on Amazon but that's probably because it only became available 2 weeks ago. I can get 200aH battery for roughly $800USD

Don't know about those ones.

To replace my single lead battery in my camper, I did order 2 of VoltXcell batteries https://www.amazon.com/Lithium-Batt...d=1&keywords=voltxcell&qid=1599330428&sr=8-13

which are working fine for me: they have powered my fridge for 3 days at least.
I've not run full capacity tests, but I am happy with those so far.
