This application relates to a battery pack and a vehicle. The battery pack includes a box and a cell module. The box contains a cavity with an opening on one side. The cell module is accommodated in the cavity. A plurality of limiting grooves are spaced apart on an inner sidewall of the cavity. Convex ribs in one-to-one correspondence with and in fit with the limiting grooves are disposed on an outer sidewall of the cell module. A potting clearance that communicates with the opening is defined by a part of the inner sidewall of the cavity and a part of the outer sidewall of the cell module. The part of the inner sidewall of the cavity is configured to avoid the limiting grooves, and the part of the outer sidewall of the cell module is configured to avoid the convex ribs.
