| Battery | Shimano STEPS BT-EN605 (504 Wh, 36 V) |
|---|---|
| Native drive system | Shimano STEPS EP8 / EP801 / EP600 |
| Verdict | fits (native pack) |

| Will not fit | a different drive system, or a different Bosch/Shimano generation even if the shape matches |
The Shimano STEPS BT-EN605 is proprietary to the Shimano STEPS EP8 / EP801 / EP600 drive, so it fits that system and no other. The BT-EN605 is the 504 Wh semi-integrated frame pack for the EP801 and EP600 drives, mounted on the BM-EN600 holder. It is the frame-mount sibling of the in-tube BT-EN805 and charges in about 5.5 hours.
Confirm the mount and the Higo / Julet charge and signal connector on your own frame, because packs that look identical across generations do not always interchange.
