Bafang BT F380 in-tube e-bike battery: 48 V, 20 Ah (960 Wh), 21700 cells, IP X6. Wholesale, quote-only supply.
At a glance
The F380 and F381 are Bafang’s largest in-tube packs at 960 Wh (48V 20Ah). They are listed with UL2271 rather than CE, which points them at North-American high-power bikes where range matters more than weight.
Bafang lists this battery in the In-tube 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.
