Hard to tell if it includes a BMS and what type of LFP cells. The price is also hard to decipher. Could be a good deal depending on freight and contents. What do you know about seller?

The size is different depending where in the description you look. It is also difficult to tell what the following means,
''Built in 12.8V BMS Transformer 220v used 3.2v 105ah"
When someone is that loosey goosey with the descriptions it is hard to form a positive conclusion about the quality of the used cells. Or is the transformer used? or maybe it is a BMS Transformer, whatever that is?

I don't know if the word "used" in the title means they are used cells. "100Ah 12v Lithium Ion Battery Pack for Solar battery Camper Built in 12.8V BMS Transformer 220v used 3.2v 105ah " Or what Transformer 220v means.
Also, the container label reads 4S1P, but the description reads 4S2P and the capacity reads 200ah, I would confirm all these values, and also ask who the cell manufacturer is. The company seems legit, if you believe its page on AliExpress.

Yes, they make it hard to know what to believe.
Someone else bought the 24 volt version. You could post in his thread and ask how it's holding up.
First Build | A portable solar power station that isn’t ugly
I wanted to make a stand-alone home backup unit that was modular and small enough to move easily— but robust enough for sustained power tool use and 2+ days of emergency lighting and refrigeration. Stretch goal: an attractive form factor that doesn’t involve a hand truck. To keep the build...

As has been suggested I would be asking questions. Who is the cell and BMS manufacturer, are the cells new, are they matched and anything else you can think of.
