The design of the BT-EN605 battery from Shimano lowers the center of gravity for a more natural riding experience and is particularly suitable for use on the E-MTB. The compact lithium-ion battery is designed for mounting on the down tube or seat tube of the frame.
Thanks to the 2nd generation STePS battery management system, the use of high-quality cells and the capacity of 504 Wh, riders benefit from an increased range and shorter charging times. Even after more than 1,000 charging cycles, the long-lasting battery still offers 60 % of its original capacity. The extremely resilient construction is highly water-repellent (IPX5), which is not only ideal for use in all weather conditions, but also allows cleaning with low water pressure.
