Compatibility answer

Will the Shimano BT-E6001 battery (504 Wh, 1st gen) work with the Shimano STEPS DU-E5000 drive unit?

Yes. Both use Shimano STEPS 1st-gen rear-carrier battery (BT-E6000 / BT-E6001).

Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.

Why

  • ✓ Both use Shimano STEPS 1st-gen rear-carrier battery (BT-E6000 / BT-E6001).

Good to know

  • Shimano's compatibility chart pairs these with BM-E6000-A/-B mounts; not listed for DU-E8000/E7000/E8080.
  • Shimano Gen.2 (BT-EN..., used with EP801/EP600/EP500) and 1st-generation (BT-E...) components: 'With some exceptions, first-generation and Gen.2 products ... are not compatible with each other.' Gen.2 batteries and mounts are marked 'Gen.2'.
  • 'EP8' is used for both the DU-EP800 (1st gen) and DU-EP801 (Gen.2), and 'EP6' for DU-EP600 (Gen.2); check the drive-unit model number, not the marketing name.
  • Shimano: 'It is recommended to use a SHIMANO genuine battery' and 'Use the specified battery and battery charger combination for charging.'
  • The battery must also match the bike's battery mount and frame; Shimano's chart lists compatible mounts per battery. Watt-hours here are 36 V x the Ah Shimano states.
  • Safety: use only batteries and chargers the drive-system maker approves. Lithium batteries that don't match can overheat.
