The Hailong 48 V 17.5 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 17.5 Ah Hailong is a common OEM-style conversion pack, balancing weight and range on a 48 V BBS02 or hub kit. Match the pack voltage to the motor and confirm the discharge connector before ordering.
Confirm the mount and the XT60 discharge connector on your own frame, because packs that look identical across generations do not always interchange.
