Shimano BT-EN805 504WH Battery

The Shimano STEPS BT-EN805 is a high-quality, long-lasting 504Wh lithium-ion battery designed for integrated frame mounting on compatible Shimano STEPS E-Bike systems. Featuring Shimano's second-generation battery management system, it delivers reliable power, consistent charging performance and excellent durability, making it ideal for demanding E-MTB riding.

Its compact, low-profile design allows the battery to fit neatly inside the frame's down tube, providing a clean, integrated appearance while offering improved resistance to impacts and vibrations. The waterproof construction helps protect the battery against wet and muddy riding conditions, while its high 504Wh capacity (36V, 14Ah) provides excellent riding range, potentially exceeding 100km in normal assistance mode depending on terrain, riding conditions and assistance settings.

Designed for long-term reliability, the BT-EN805 offers approximately 1,000 full charging cycles while retaining more than 60% of its original capacity. A full charge takes approximately five hours, while the integrated charge level display, error signal information and on/off switch make battery monitoring and operation straightforward. The battery also features a charging port and locking system for added security.

Important Compatibility Information: This battery features Shimano's second-generation (Gen.2) battery management system and is designed exclusively for Shimano STEPS DU-EP801 and DU-EP600 drive units. It is not compatible with older first-generation Shimano STEPS systems. Please check your existing battery, motor and mounting system before purchasing.
