    I guess they're asking where to actually buy them at these prices, not doubting that the price is dropping.

      Ah, those are wholesale prices. And the form factor will increasingly be prismatic LFP packs, not cylindrical cells. For buying LFP cells, I would start here: https://diysolarforum.com/ https://diysolarforum.com/

  Might be the form factor. I think most of the big companies have moved away from 18650 cells. The cheapest full packs (not cells) in the US are $800 for 5kwh. Search “Server Rack Battery” on eBay, amazon or alibaba. These things are way cheaper than they were 12 months ago. The raw cells can be had even cheaper, but they require more specialized knowledge and equipment to use.

  Yea and I don't see EV prices dropping either.

  To see if anything is getting cheaper over the time, especially long term it's useful to adjust for inflation - if everything getting more expensive fast but Li-ion prices rise slower than other goods - adjusted for inflation Li-ion getting cheaper.
