Does a Hailong 48 V down-tube (Bafang) fit a Yamaha PW-X3 / PW-ST / PW-TE bike?
Whether a Hailong 48 V down-tube (Bafang) fits a Yamaha PW-X3 / PW-ST / PW-TE e-bike, and the pack you actually need.
No. The Hailong 48 V down-tube (Bafang) is a Bafang pack and a Yamaha PW-X3 / PW-ST / PW-TE bike needs a Yamaha pack. Batteries are proprietary per drive system and do not cross over.
| Battery | Hailong 48 V down-tube (Bafang) (Bafang, about 960 Wh at 20 Ah) |
|---|---|
| Target system | Yamaha PW-X3 / PW-ST / PW-TE (Yamaha) |
| Verdict | does not fit |
| Reason | different brand, mount and charge port; Bafang and Yamaha packs are not interchangeable |
| What to buy instead | a Yamaha PW-X3 / PW-ST / PW-TE pack such as the Yamaha Intube 500 Wh |
E-bike batteries are proprietary to the drive system, which is the whole point of the design. The Hailong 48 V down-tube (Bafang) is a Bafang pack for Bafang BBS02 / BBSHD / mid drive, while a Yamaha PW-X3 / PW-ST / PW-TE bike needs a Yamaha pack with the Yamaha mount and charge port. They do not cross over.
For a Yamaha PW-X3 / PW-ST / PW-TE bike, fit a Yamaha pack such as the Yamaha Intube 500 Wh (500 Wh, 36 V in-tube).
