48v single cell lithium ion battery

I'm searching different options for batteries.

I saw a comment on one of the videos basically stating there was restrictions regarding a lower voltage battery used in a bank.

So my question is this. Is this battery a viable option for my needs? If not, why? What would be a better option? Im limited on funds for the time being and the funds I have are draining quickly to supply gas for my generator.

I already have onsite 12 230w solar panels and a 48v all in one converter to power everything in two RVs. With the capacity to expand. Link below for reference and specs.

That would power a light bulb for a short time .
What model inverter do you have? Will it work without batteries ?
Maybe second hand or new forklift batteries might be better choice for you. Lithium is expensive and you are going to need a lot of power. 12 of 230w panels means 2760 watts available at peak sun which might happen sometimes but not that often but its a start.
An inverter that does not need grid connection or batteries would seem to be the best choice but they are up over a grand.
