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.
