I suspect the original picture is from either the end of the assembly line or a shipping facility. Your first clue that it’s not in a pack is the lack of connections between the batteries. Nobody makes an all parallel pack. 3V at how many amps would be too hot. They wire a bunch in series to triple digit voltages and then comment those packs together in parallel.

You could probably ship them staggered, but I’m betting they are at a weight limit anyway so making them more dense doesn’t save you anything.
