[0005] This patent has some disadvantages when used, such as: when multiple lithium battery packs need to be installed, they need to be installed in sequence, which will result in the installation being not neat and the two adjacent lithium battery packs not being close enough, and the lithium battery packs may be exposed to the outside for a long time and dust may enter the lithium battery pack, which may affect the heat dissipation of the battery pack, resulting in a decrease in the performance and life of the lithium battery pack. In view of this, we propose a lithium battery pack that is easy to splice and use. Utility Model Content
