The Bafang fat-bike conversion (48 V) runs the Bafang BBS02 / BBSHD / mid drive, a Bafang drive whose battery is proprietary to the system, so the replacement pack is one of its own, most often the Hailong 48 V down-tube (Bafang) (48 V, up to 20 Ah, XT60), charged through the XT60 discharge connector.
Match the pack voltage to the motor rating (a 48 V BBS02 wants a 48 V pack, not a 36 V one), and confirm whether the controller uses an XT60, an Anderson or a bullet connector before ordering the battery.
