| Battery | Hailong 52 V 14 Ah down-tube (Bafang) (about 728 Wh at 14 Ah, 52 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 52 V 14 Ah down-tube (Bafang) is proprietary to the Bafang BBS02 / BBSHD / mid drive drive, so it fits that system and no other. A 52 V 14 Ah Hailong gives higher top-end voltage than a 48 V pack at similar weight. A 52 V pack peaks near 58.8 V charged, so confirm your controller and display are rated for it before fitting.
Confirm the mount and the XT60 discharge connector on your own frame, because packs that look identical across generations do not always interchange.
