To not do so means you will miss out on the improved energy density that lithium allows. Which is the whole point. And will not take advantage of the increased lifespan possible. Lithium hated high discharge rates, and being full, or empty. So a large pack means you charge less frequently, and work each cell less hard.
For EG one of my chairs uses 120Ah lithium, the new chair I just aquired will be getting 180Ah. The smallest pack that makes any sense is about 90Ah as used by expresso in new york.

Why not use differential axles ? They have high/low gears too .
Around US$ 90 --- 200 .
Can be very short wheelbase.

1500W motor plus rear axle completed with high/low gear shift is US $120.00 , and others lowest as $60.00.
