Are you looking for a reliable power source for your e-bike that fits discreetly into the frame? The Shimano BT-EN805-A is a high-quality, integrated lithium-ion battery designed specifically for a clean look in the down tube. With a capacity of 504 Wh, it offers you an excellent balance between weight and range – ideal for daily commuting or extensive weekend tours.

Thanks to Shimano's modern cell technology, you benefit from a long lifespan and consistent power output, even when tackling steep hills. The black casing visually disappears within the frame, while the robust design ensures that vibrations and shocks on uneven paths are not an issue.

Care & Handling Tips

• Charging: Always use the original Shimano charger for a long lifespan. It's best to charge the battery at room temperature, as extreme cold or heat can strain the chemical processes within the cells.

• Storage: If you leave your e-bike unused for a long time in winter, remove the battery (if possible) and store it dry at around 10°C to 20°C. A charge level between 30 % and 60 % is optimal to avoid deep discharge.

• Cleaning the Contacts: Always keep the connector sockets on the battery and bike clean. A dry cloth or a bit of contact spray (specifically for electronics) works wonders to prevent corrosion and ensure loss-free power transmission.

• Safety: Always check after inserting whether the battery is securely locked in place. A properly seated battery is essential for trouble-free electronics during the ride.
