Those are some odd cells… they’re shaped like 2 18650’s wrapped together actual dimensions are “37.2 x 64.8 x 19.1mm”
Nominal voltage of 3.65 x 12 = 43.8. So 12S, but from the looks of the block it’s 12S4P. I was thinking 12S8P but since they’re essentially a double width 4P.
Power wall cells are usually not a good fit for eskate, but those can supply 13A so in 4P you could have 52A which is enough, and 21.2Ah plenty of range. however if you stick all those cells on a board and your looking at about a 20lbs battery. If it’s a really good deal on the cells, it’s possible I guess, but a normal 18650 is a whole lot easier. Never know if there are some weird quirks with that kind of battery cell.
