Bafang BBS02 / BBSHD / mid driveDoes the Hailong 48 V 14 Ah down-tube (Bafang) fit a Bafang BBS02 / BBSHD / mid drive bike?
Whether the Hailong 48 V 14 Ah down-tube (Bafang) fits a Bafang BBS02 / BBSHD / mid drive e-bike, and what to confirm on your own frame first.
Yes, with the right mount. The Hailong 48 V 14 Ah down-tube (Bafang) is the native pack for a Bafang BBS02 / BBSHD / mid drive bike (about 672 Wh at 14 Ah, 48 V), charged through the XT60 discharge connector.
| Battery | Hailong 48 V 14 Ah down-tube (Bafang) (about 672 Wh at 14 Ah, 48 V) |
|---|---|
| Native drive system | Bafang BBS02 / BBSHD / mid drive |
| Verdict | fits (native pack) |
| Charge port | XT60 discharge connector |
| Will not fit | a different drive system, or a different Bosch/Shimano generation even if the shape matches |
The Hailong 48 V 14 Ah down-tube (Bafang) is proprietary to the Bafang BBS02 / BBSHD / mid drive drive, so it fits that system and no other. The 48 V 14 Ah Hailong pack is the mid-capacity conversion battery, a lighter option than the 20 Ah pack for a 48 V BBS02 or hub kit. It ships with an XT60 or T-plug; confirm whether your controller uses XT60, an Anderson or a bullet.
Confirm the mount and the XT60 discharge connector on your own frame, because packs that look identical across generations do not always interchange.
