Why not non-lithium batteries?
Apparently wp:nickel–iron batteries are safer and less harmful to the environment.
Slow charge/discharge rates, cycle efficiency (in vs. out) is much lower than lithium, much heavier and bigger for the same capacity, liquid electrolyte to spill, generates hydrogen gas when charging.
Basically, it's the wrong battery for this kind of application. Great for a house battery charged off a lot of solar that you want to keep for 50 years. Not so great for a scooter.
