I see them on ebay, modules are 2 cells, I'm assuming 24ah and people want $90 to $100 for them.
That's still $700 for 1 useable KwH if the cells actually hold 24ah and they are 24ah.

Now if you bought an entire used battery that would be $200 to $400 KwH then you still have to take it apart and rearrange the cells for normal useable voltage unless you have a lead on an inverter that will convert leaf 400vdc to single phase AC?
