Different cars have different strategies. Here's a random eBay buy-it-now, for a 24V 250Ah 5.2kWh cell out of a a Tesla S 85, https://www.ebay.com/itm/115749249082 https://www.ebay.com/itm/115749249082 , $340. Google is telling me conflicting data on the S, saying twice the capacity. But also nicely explains the cell configuration: > The 5.3 kWh battery module in the Model S and Model X vehicles is made up of 444 Panasonic NCR18650B cells in a 74p6s Then a number of these 5kWh modules are combined in the car. But like, I have a LTO battery from a Honda plug in hybrid that uses much much bigger rectangular cells than the 18650 cylinders and is just like 12s1p or some such. I forget the figure exactly but capacity is much less than 5kWh.
