You can select your battery's Voltage and Capacity (Ah) values from the product options. This way you can choose the battery that matches your riding habits and range expectations.
The following details are shown clearly next to the option you select:
Every cell used in Byqee batteries goes through detailed testing before production.
Only cells verified to be in the %95 – %100 SoH (State of Health) range are put into production.
Think of capacity ("Ah") like a fuel tank. The higher the Ah value, the more energy your battery stores and the further you can ride.
Higher Ah = longer range.
Beyond that, it has no other effect, positive or negative, on motor performance or on the electrical system. A change in the "Ah" value doesn't mean you need to replace the motor, the controller or the wiring. Your bike keeps working exactly as it does now.
Range figures are calculated based on the original range stated by the bike's manufacturer.
Example: On a bike rated at 50 km with a 10Ah battery, increasing the capacity to 25Ah gives a theoretical range of around 125 km.
️ Real-world range varies with speed, riding style, gradient, rider weight and ambient temperature.
For this reason, range is not guaranteed. The battery's capacity, however, always matches the stated value.
Charging time depends on the battery's capacity and on the amperage of the charger you use.
Example: A 10Ah battery reaches a full charge in around 5 hours with a 2A charger.
If you want faster charging, you can browse our higher-amperage chargers on the "Chargers & Accessories" page.
