The F501 mounts on the outside of the down tube and slides upwards off its base, so it fits frames that have no integrated battery bay. One 366 mm housing covers 36V 540/720 Wh and 48V 748 Wh.
Bafang lists this battery in the Downtube group of its OEM component catalogue and in the 2027 OEM workbook. Every figure on this page comes from those two sources; Bafang does not publish chemistry details, cycle life or weight for it, so ask for the cell datasheet before ordering.
The pack is supplied to bike makers as an OEM part. Check the frame interface, lock and connector version against your frame before placing an order.
