There has been much speculation and difference of opinion on the actual cost of a Tesla battery pack. At a cell level, retail prices for commodity 18650 cells can come down to around $4 each, so that would be ~$27K (6831*$4) just for the cells not counting all the other stuff that goes into an ESS "Battery box" but we assume Tesla gets a much better than retail deal on a per cell basis.
Comments about battery pack and cell prices have been scattered all over the place on this forum, so I thought I should start a new topic just for this subject.
Along with all the variance between wholesale and resale price (both for the cells, and the completed battery box), there have been discussions about the differences in prices between Tesla's Lithium-Cobalt "commodity laptop" cells and other types of Lithium-Iron-Phosphate batteries that have different characteristics but are also being used in EVs.
Note, Tesla says they use premium well known brand cells (although the particular manufacturer is not stated), but some of the costs comparisons are being made against upstart Chinese brands.
With all that said, here were some "bargain basement" prices seen on the net recently:

...The price available is $1.10 per Ah plus customs, container shipping, etc. Expect about 10% extra for those costs...
...The SE 180 Ah cells are interesting because they have the same physical dimensions as the Thundersky 160 Ah cells but are more energy dense at 102 wh/kg and 159.48wh/l ...
