This 48V 15Ah electric bicycle battery provides a reliable power source for your daily commutes or longer weekend excursions. Depending on your riding style, the terrain, and the weather, you can expect an autonomy of roughly 70 to 80 km on a single charge. To keep the cells safe, the unit includes intelligent protection systems that prevent overheating and overcharging. The internal components are housed in a black plastic casing featuring an integrated lock and key, allowing you to secure the battery to your bike frame when not in use.
