Can the battery of an electric car be used on a motorcycle

Motorcycles, electric vehicles, and car batteries are all 12V and can be replaced with each other, as long as there is a place on the car to place these batteries of different sizes. (The so-called 36V and 48V electric vehicles refer to connecting multiple 12V batteries in series).
The biggest difference between the above 3 kinds of batteries is:
1. Motorcycle: Since it only needs to start the power supply and lighting power supply, and the engine can be charged after starting, but the battery compartment is usually small, so the capacity and volume are small, usually 4~8Ah.
2. Electric vehicles: Since all power and lighting come from batteries and cannot be recharged by themselves, the capacity is relatively large, usually 10~20Ah
3. Car: Since the startup consumes more power, and there are many electrical equipment, there is enough space to accommodate a large battery compartment, so it is usually more than 30 amp hours.
As for whether to add water, it depends on whether the battery is a dry battery or a wet battery. Therefore, replacing an electric vehicle battery with a suitable size can make your motorcycle more sufficient, especially for motorcycles that are more power-hungry such as xenon lights.
Electric vehicle battery:
The vast majority of current electric vehicles are equipped with lead-acid batteries, because lead-acid batteries are low-cost and cost-effective. In 1860, France's Plante invented a battery with lead electrodes. The unique feature of this type of battery is that when the battery voltage drops after a period of use, a reverse current can be applied to it to make the battery voltage rise. Because this kind of battery can be charged and can be used repeatedly, it is called "lead-acid battery".
