Why not use a large battery to drive Low Speed Vehicle Golf Cart ?

Why using many small batteries rather than a large battery to drive Low Speed Vehicle Golf Cart ?

There are several reasons:
1) Cost - being produced for quite some time now and are already widely used throughout the worldby far, they are the cheapest lithium ion cells available out there.
2) Thermal performance - Cooling is much easier and easy to control. manufacturer can have a cooling system around several cells and cool them much better rather than trying to cool one huge hunk of a pack from outside.
3) Reliability - Because of the decade long experience of cell manufacturers with this particular standard, quality has really improved.
4) Isolation - in case of a failure or a fire, it is much easier formanufacturer  to individually isolate these cells  thus making the packs super-safe. Larger cells will lack this feature and can potentially become a bomb in case of an event like thermal runway.
