In this embodiment, the depth value of the insertion hole is smaller than the length value of the battery unit 310.

One end of the battery unit 310 is inserted into the jack, so that the battery unit 310 is fixed and conductively connected. In order to allow the battery cell 310 to be sufficiently contacted with the flowing air current, the battery cell 310 is exposed except for the portion inserted into the insertion hole, so that the contact area with the air current is increased, and the heat accumulation is reduced.

A gap may be formed between two adjacent battery cells 310 along the circumferential direction of the mounting seat 320.
