Battery cell protection circuit board and battery

The utility model discloses a battery cell protection circuit board and a battery. The battery cell protection circuit board comprises a flexible circuit board and a flexible protection layer, the flexible circuit board is provided with a cell protection circuit and a component. The cell protection circuit is electrically connected with the component; the flexible protection layer covers the two sides of the flexible circuit board, and the flexible protection layer covers the pins of the components, so that the pins of the components are not exposed. The circuit board adopts the flexible circuit board, the hardness is low, the bending process is easy to control in the process of bending to the top sealing groove, the risk that the edge of the battery cell protection circuit board is in contact with the battery cell aluminum plastic film in the bending process to scratch the battery cell aluminum plastic film is avoided, and meanwhile, the flexible circuit board is covered with the flexible protection layer, s
