Will the Shimano EC-E8004 e-bike battery charger work with the Shimano DU-EP500 (EP5, Gen.2) drive unit?
Yes. Both use Shimano STEPS / E-BIKE charger (EC-E6002, EC-E8004).
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 / E-BIKE charger (EC-E6002, EC-E8004).
Good to know
- Charging a battery off the bike needs an adapter for some models: SM-BTE60 (e.g. BT-E6000/E6001/E6010, BT-EN404/405) or SM-BTE80 (e.g. BT-E8035/E8036, BT-EN805/806); sold separately.
- The older EC-E6000 charger 'does not support the charging of batteries with model names ending with -A' (Shimano manual).
- Shimano notes the list 'Includes batteries that may not be usable in your region.'
- Safety: use only batteries and chargers the drive-system maker approves. Lithium batteries that don't match can overheat.
