In addition, the features defined as "first", "second" can explicitly or implicitly include one or more features.

[0034] Referring to Figures 1-3 A lamp includes a shell 200, a lighting part 300 and a connecting piece 400 connecting the shell 200 and the lighting part 300. A battery 100 and a control module 500 for driving the lighting part 300 are arranged in the shell 200, and the battery 100 and the control module 500 are electrically connected.

[0035] Referring to Figures 3-8 The battery 100 includes a shell 1, a battery core 2, a charging interface 3, a tab group for electrical connection and a control circuit board 5, the battery core 2 and the control circuit board 5 are arranged in the shell 1, and the control circuit board 5 can detect the state such as the power and temperature of the battery core 2, and control the charging operation of the battery core 2.

[0036] The shell 1 is in a strip shape, and the shape and size thereof are matched with the battery core 2 respectively. The shell 1 has a first end portion 11 and a second end portion 12 opposite in the length direction, the battery core 2 is arranged spaced apart from the first end portion 11 of the shell 1 so that a certain accommodation space exists therebetween, and the control circuit board 5 is arranged in the accommodation space. A first recess 13 is formed in the position close to the first end portion 11 of the outer peripheral wall of the shell 1, the first recess 13 is formed by the outer peripheral wall of the shell 1 being recessed inwardly, and the first recess 13 penetrates the first end portion 11, and the first recess 13 can also communicate with the internal space of the shell 1.

Each contact piece is electrically connected to the control circuit board 5. In addition, the control module 500 of the lamp is also electrically connected to the corresponding contact piece through three elastic connecting terminals 501. Thus, the battery 100 can supply power to the power supply object (the lighting part 300 in the embodiment). Each connecting terminal 501 is inserted into the first groove 13 and is pressed on the corresponding contact piece. Since the first grooves 13 are circumferentially spaced along the outer circumferential wall of the shell 1, each connecting terminal 501 is in contact with the corresponding contact piece by applying force from the outside of the shell 1 to the inside, which is conducive to the stable connection of each connecting terminal 501 and the corresponding contact piece. In addition, since the circumferential space of the outer circumferential wall of the shell 1 is large, each connecting terminal 501 is positioned in the corresponding first groove 13, so that the interference between each connecting terminal 501 (contact piece) and the other connecting terminals (contact pieces) can be avoided, and even short circuit can be avoided.
