2 Volt OPzV batteries?

While attempting to select batteries for my 55 Safari solar power setup I came across references for 2V sealed batteries.

One site notes the following:
"OPZV Sealed Lead Acid Tubular Sla Battery 2V 500AH,High Reliability and Quality lead acid battery with Longer Service Life , it is the best choice of solar system"

Is anyone here using a bank of 2V batteries in their RV?

What are the advantages or disadvantages of a 2V bank of batteries in a 12V system with inverter for 120V appliances?

You are gonna need 6. And at 500ah, I would reckon they weigh close to 250lbs... Each.

Size and weight are most critical, hence the move to lithium

I see. Not too practical for RV
I am now looking at the Carbon Foam batteries.
Oasis g31
Any thoughts or experience here?
I like the look of this battery system.
I have all I need for my photovoltaic power system except the battery.
