The company is only 1 year old, I would not really trust them yet at this point.
What is the shipping charge to your country?
Did you ask them to show the pictures of the inside of the unit so we can see the construction of the unit?

Price is low, but not impossible. I don't know the current price of 200Ah cells, but in the past 230Ah cells were $65 or so, and 100Ah cells $35 ex shipping. (Higher Ah cells have beter $/Ah price)
So assume $60 or so for a 200Ah cell, 16 cells would be $960. Leaves $240 for the case and BMS....

So yes, from a price perspective, it seems possible using common bulk cells. For fully matched cells, I doubt. However, there is still a risk of lower quality cells, and/or bad internal constructions.

And with a rather new seller, it's always a bet. If you want to be the test.. go ahead. Might be a good deal, but it also might not if you're getting crap.

Keep in mind that 48V / 200Ah is going to be massive in weight. For maintenance and handling it might be better to go for 2x 100Ah sets.

Wondering how they would come up with 200Ah....
9 cells in parallel, so each cell would be 22.22Ah?

Sounds like a strange cell value to me. If they are 25Ah cells, 9x would be 225Ah...

And I still have to find a Chinese seller which will advertise cells BELOW their rated capacity.. It's more commonly to overrate cells...

Or there are some kind of 22.22Ah cells, or they are derated 25ah cells?
