The Shimano STEPS BT-E8016 is a high-capacity 630Wh down tube battery built for the E8000 series e-MTB system. Offering Shimano's largest external battery capacity at the time of release, it gives serious trail riders the range to push further on every charge — while its compact, low centre-of-gravity design keeps handling natural and confidence-inspiring.

Highlights

  • 630Wh capacity: Maximum range for demanding trail and enduro riding on the E8000 platform.
  • Quick charging: Reaches 50% in just 2.5 hours and full charge in 6 hours with the EC-E8004 charger.
  • Long cycle life: Retains over 60% of total capacity after 1,000 charge cycles for lasting performance across the life of the bike.
  • Low centre of gravity: Down tube mounting position keeps mass centralised for balanced, natural handling off-road.
  • Charge level display: Integrated LED indicator lets you check remaining charge at a glance, on or off the bike.
  • Key-lock security: Battery is secured to the frame with a key-operated lock, allowing tool-free removal for charging away from the bike.
  • On/off switch & error signal: System switch and built-in error signal provide rider control and quick diagnostics.

Charging & Battery Life

The BT-E8016 is compatible with the EC-E8004 and EC-E6002 chargers. Typical charge times with the EC-E8004: 50% in 2.5 hours, 80% in approximately 3.2 hours, 100% in 6 hours. Note: the BT-E8016 is not compatible with the older EC-E6000 charger. The Li-Ion chemistry is engineered for durability — after 1,000 full charge/discharge cycles, the battery retains more than 60% of its original capacity.

Compatibility & Fit

Designed for the Shimano STEPS E8000 series e-MTB drivetrain system. Mounts to the down tube using the dedicated BM-E8016 battery mount (sold separately — required; not compatible with older BT-E8010 mounts due to the larger physical size of the 630Wh cell). Compatible with E8000 series drive units. Confirm frame compatibility with your bike manufacturer before purchasing.
