Sorry about the picture. I don't have another file service. I will put the image on my webpage if it still works.
Cor has it right. It is 16 "cells" making a 48V pack of LFP. The cells are each a group of parallel cells. Sold as a 20Ah pack (who know how accurate that is) and it does indeed put out about 1kWh. The groups have a strip of stainless (my presumption) with 4 tiny spot welds on between the strip and each individual cell. The 16 cells are connected in series with shorter strips also spot welded in place. It is clear that with the right combination of voltage and current that you can weld them together without starting a fire. What that combination is, I can say, but it won;'t be a very powerful setup and there is no real reason why it has to be expensive. I guess no one has tried this, yet? It seems pretty effective from an end user POV.
