When choosing a lithium-ion battery for a scooter, there are a few important things to consider. First, pay attention to the battery capacity, which affects the range. Typically, the higher the capacity (in Ah), the further you can travel on a single charge. But keep in mind that such a battery will be heavier. Second, it is important to consider the battery voltage. Scooters usually use batteries with a voltage of 36V or 48V. The higher the voltage, the more powerful your scooter will be, but the battery must be suitable for your model.
