Abstract: Provided are a battery and an electric device, belonging to the field of battery technologies. The battery includes: a plurality of battery units, the plurality of battery units being arranged in a first direction; and a bundling assembly, the bundling assembly including a plurality of bundling members and first protective members; the plurality of bundling members being provided in correspondence with the plurality of battery units, and each of the bundling members being configured to bundle a corresponding battery unit; and each first protective member connecting two adjacent bundling members to limit deformation of the bundling members.

Abstract: A battery includes a battery pair and an information collector configured to collect parameters of the battery. The battery pair includes two battery cells. A surface of each of the two battery cells is provided with a pole. The poles of the two battery cells abut against each other face to face to form a pole assembly structure. The pole assembly structure includes an insertion slot. The information collector includes a main board and a sampling piece electrically connected to the main board. One end of the sampling piece extends into the insertion slot and is electrically connected to the pole assembly structure.
