I have 24 Nissan leaf cells available. 8.2v, 55ah approx. From a 2012 Leaf. Im using the remainder in a Motorhome conversion. $160 Each. Can be freighted.

8.2V would be 2 cells in series, wouldn't it?

They are an unusual configuration, 2s2p in each "cell" So each individual cell has 4 4.1v pouches inside.

These are the normal Lithium Iron Phosphate batteries similar to Winstons and all the others.

The only peculiarity is that each Leaf battery module contains a pair of 55 Ah cells in series and has three output terminals on the top of each module, instead of the more usual two for a single cell.
Charging voltage is 4.1 volts and lowest recommended discharge voltage 3.0 volts per cell.
Nominal voltage is probably around to 3.25 volts per cell, and one Leaf module maybe 6.5 volts nominal for both the cells each module contains at about the 50% discharged level.

So you would normally need two of these Leaf modules for a 12 volt system, and eight for a 48 volt system.

Only a few weeks ago I looked into importing some of these Leaf modules from the US myself, but bringing them into Australia was problematic, so decided to go with some brand new 60 Ah Winstons instead.

These could be a good deal for someone, as the price is well below what I paid for the Winstons.
