Battery Technology
The BT-EN806 uses a lithium-ion cell pack operating at 36 V with a 17.5 Ah rating, delivering 630 Wh of usable energy. The flat integrated design was engineered specifically for Shimano's second-generation STEPS battery mount system, allowing frame manufacturers to build slimmer, more natural-looking e-bikes. The battery charges safely between 0 °C and 40 °C and operates in temperatures from −10 °C to 50 °C, covering the full range of Australian riding conditions.
Durability & Longevity
Shimano rates the BT-EN806 to retain more than 60% of its original maximum capacity after 1,000 full charge cycles — representing years of regular riding before any meaningful performance decline. IPX5 certification means it handles rain, trail spray, and post-ride washdowns without issue. The battery also features an error signal function that alerts the rider or technician to any fault condition, making diagnostics straightforward.
Compatibility & Fit
The BT-EN806 is compatible with the Shimano STEPS DU-EP801 and DU-EP600 drive units. It requires a second-generation Shimano STEPS integrated battery mount — compatible brackets include BM-EN800-A, BM-EN800-B, BM-EN801-A, and BM-EN801-B. Recommended chargers are the EC-E6002 and EC-E8004. This battery is supplied as a replacement or upgrade unit; frame compatibility should be confirmed with the bike manufacturer before purchase.
