Can the batteries of 2-wheeled and 3-wheeled electric vehicles be changed?

2-wheeled electric cars are generally only 12v batteries, but the 2-wheeled electric vehicle battery capacity is small, the normal is 12Ah or so, and 3-wheeled electric vehicle battery only is 12V, but much larger capacity, some battery capacity in 20-35Ah or so, if you want to change, all should be changed, because the voltage is consistent, Capacity depends on the size of the battery compartment of two vehicles, the premise is consistent voltage, consistent capacity.
