Yamaha PW-X3 / PW-ST / PW-TEDoes the Yamaha frame battery 500 Wh fit a Yamaha PW-X3 / PW-ST / PW-TE bike?
Whether the Yamaha frame battery 500 Wh fits a Yamaha PW-X3 / PW-ST / PW-TE e-bike, and what to confirm on your own frame first.
Yes, with the right mount. The Yamaha frame battery 500 Wh is the native pack for a Yamaha PW-X3 / PW-ST / PW-TE bike (500 Wh, 36 V), charged through the Yamaha PW-series charge connector.
| Battery | Yamaha frame battery 500 Wh (500 Wh, 36 V) |
|---|---|
| Native drive system | Yamaha PW-X3 / PW-ST / PW-TE |
| Verdict | fits (native pack) |
| Charge port | Yamaha PW-series charge connector |
| Will not fit | a different drive system, or a different Bosch/Shimano generation even if the shape matches |
The Yamaha frame battery 500 Wh is proprietary to the Yamaha PW-X3 / PW-ST / PW-TE drive, so it fits that system and no other. The Yamaha 500 Wh frame pack (reference PASB5) mounts on the down tube. The 400 and 500 frame packs share the mount, so a 400 bike can be upgraded to 500 for range.
Confirm the mount and the Yamaha PW-series charge connector on your own frame, because packs that look identical across generations do not always interchange.
