In Stock
The Shimano STEPS BT-EN805 delivers 504Wh of integrated battery power for e-MTBs and e-bikes running the EP8 or EP6 drive system. Its slim, flat profile integrates cleanly into the down tube or seat tube of purpose-built frames, keeping weight centralised and the centre of gravity low for a riding feel that stays close to a conventional bicycle.
Highlights
- 504Wh capacity (36V / 14Ah) — substantial range for trail and commute riding
- Slim, flat form factor enables slimmer frame designs and lower centre of gravity
- Second-generation Shimano STEPS battery management for optimised performance and longevity
- IPX5 water resistance — suitable for all-weather riding and low-pressure washing
- Built-in charge level indicator, on/off switch, and error signal
- Retains over 60% of initial capacity after 1,000 full charge cycles
- Compatible with DU-EP801 (EP8) and DU-EP600 (EP6) drive units
Battery Technology
The BT-EN805 uses Shimano's second-generation lithium-ion cell chemistry paired with an advanced battery management system. The management system monitors charge cycles, thermal conditions, and cell balance to protect long-term capacity. Charging from flat to 80% takes approximately 2.5–3.2 hours with a compatible EC-E8004 charger; a full charge is reached in around 4.0–4.5 hours.
Frame Integration
Designed specifically for frame-integrated mounting, the BT-EN805 slots into the down tube or seat tube of compatible e-bike frames using Shimano STEPS battery mount hardware (BM-EN800-A/B or BM-EN801-A/B). The flush fit keeps the battery protected within the frame and contributes to a clean, uncluttered aesthetic without exposed battery bulges.
Compatibility & Fit
The BT-EN805 is compatible with the Shimano STEPS DU-EP801 (EP8) and DU-EP600 (EP6) drive units. It requires a frame with an integrated battery cavity and Shimano STEPS second-generation battery mount points. Compatible chargers: EC-E8004 and EC-E6002. Battery mounts: BM-EN800-A, BM-EN800-B, BM-EN801-A, BM-EN801-B. Not compatible with first-generation Shimano STEPS systems (E6000/E8000 series).
