Battery protection board and battery

The embodiment of the utility model discloses a battery protection board and a battery, the battery protection board is provided with a soft board area and a hard board area, the soft board area is divided into a non-bending area and a bending area along the length direction, and the soft board area comprises two circuit layers which are laminated along the thickness direction; therefore, the number of the circuit layers in the non-bending area and the number of the circuit layers in the bending area are both two, the structure is obviously different from the structure of an existing battery protection plate with four circuit layers in the non-bending area, and the thickness of the two circuit layers located in the bending area is smaller than that of the two circuit layers located in the non-bending area. And the hard board is arranged in the non-bending area to form the soft and hard board combination area, so that the battery protection board structure combining the two circuit layers and the hard board is
