When I was faced with choosing a lithium-ion battery for my scooter, I faced many questions and doubts. It is important to consider several key factors. First, pay attention to the battery capacity, which is measured in ampere-hours (Ah). The higher this figure, the longer the travel distance on a single charge. For example, for daily city trips, a battery with a capacity of 10 to 15 Ah is usually enough. It is also worth paying attention to the voltage (V). Scooters often use batteries with a voltage of 36V or 48V, and the higher the voltage, the more power and speed the scooter can develop. I would advise choosing a battery with the same voltage as the original to avoid incompatibility.
