Possible to DIY Something Similar to Fortress Power eVault?

You would need 20 280Ah cells to equal 18KWh storage... and it’s a 16S voltage, so... you would need over 350Ah cells to duplicate the capacity.
And you would need the rated enclosure, and the monitoring setup, but I don’t see why you couldn’t equal the build yourself.
 
How much is that fortress unit? Looks robust (and expensive)!
 
The eVault is about $10,000-$12,000 when you consider 32 cells plus BMS plus hardware plus case, you could likely make it for about 1/2 but you would not get the engineering and the warranty and some of the fancy bells and whistles it has. So if I am going to spend $40,000 on a solar system, spending an extra 15% or so for the piece of mind is likely worth it (for me, at least).
