Electric Scooter Batteries:
The battery is your electric scooter’s “fuel tank.” It stores the energy that is consumed by the DC motor, lights, controller, and other accessories.
Most electric scooters will have some type of lithium ion-based battery pack due to their excellent energy density and longevity. Many electric scooters for kids and other inexpensive models contain lead-acid batteries. In a scooter, the battery pack is made of individual cells and electronics called a battery management system which keeps it operating safely.
Bigger battery packs have more capacity, measured in watt hours, and will let an electric scooter travel further. However, they also increase the size and weight of the scooter — making it less portable. Additionally, batteries are one of the most expensive components of the scooter and overall cost increases accordingly.
