| Battery | Yamaha Intube 720 Wh (720 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 Intube 720 Wh is proprietary to the Yamaha PW-X3 / PW-ST / PW-TE drive, so it fits that system and no other. The Yamaha Intube 720 Wh is the largest in-tube Yamaha pack, for PW-S2 and PW-X3 bikes built around it. It is a 36 V pack on the Yamaha charge port, so it needs a frame designed for the 720 size.
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.
