An electronic cigarette and a battery apparatus thereof. The battery apparatus (70) comprises a cylindrical body (71), a first airflow passage (730), and two conductive elements (74, 75). The first airflow passage (730) penetrates through the cylindrical body (71) along the axial direction. The two conductive elements (74, 75) are separately disposed on two opposite ends of the cylindrical body (71), and are insulated from both the positive electrode and the negative electrode of the battery apparatus (70). The two conductive elements (74, 75) are electrically connected to each other. According to the apparatus, airflow passages are disposed on the cylindrical body of the battery apparatus, and the sizes of the airflows passages are kept consistent easily, thereby improving the consistency of a product. |
