An induction-powered device for use in an alternating magnetic field comprises: a magnetically permeable core; an electrically conductive coil surrounding the core; and an electrical load electrically connected to the coil. The coil is configured to generate a voltage when exposed to the alternating magnetic field, to power the electrical load.

A handle battery includes a casing, an upper cover, and a lower cover. The casing includes an upper-end opening, a lower-end opening, and a receiving cavity between the upper-end opening and the lower-end opening. The receiving cavity houses a battery cell that is configured to supply power for a gimbal. The upper cover covers the upper-end opening. A mounting groove is formed on the upper cover for detachable connection with the gimbal. The mounting groove includes an entrance for the gimbal to enter the mounting groove. A power supply interface is disposed in the mounting groove for supplying power to the gimbal. The lower cover covers the lower-end opening.

A battery includes a housing, a plurality of battery cells, a first part, and a second part. The plurality of battery cells is disposed in the housing. The first part includes a first contact. The first contact has a first connection to at least one battery cell of the plurality of battery cells. The second part includes a second contact. The second contact has a second connection to at least one battery cell of the plurality of battery cells.
