The Hailong 36 V down-tube (Bafang) is proprietary to the Bafang BBS02 / BBSHD / mid drive drive, so it fits that system and no other. The 36 V Hailong pack suits a BBS01 or a 36 V BBS02. Do not feed a 36 V pack to a motor set for 48 V or the bike will be down on power and may under-volt; match the pack voltage to the kit.

Confirm the mount and the XT60 discharge connector on your own frame, because packs that look identical across generations do not always interchange.
