[0030] By providing the shell 11, various internal structures can be protected to avoid damage during use or transportation, thereby effectively improving the service life of the battery. The power socket 12 provided at one end can be more conveniently connected to the device to be used. By providing heat dissipation ports 13 with dustproof nets on both sides corresponding to the positioning blocks 3, heat dissipation inside the battery can be more convenient, and external dust can be prevented from entering the interior and affecting the normal operation of the battery.

[0031] The power module 2 includes a plurality of battery cells 21 arranged in an array, the upper and lower ends of the battery cells 21 are plugged with fixing seats 22, the surfaces of the fixing seats 22 are fixedly connected with extreme connecting pieces 24, both sides of the upper extreme connecting piece 24 are connected with power connection terminals 23, and the surface of the extreme connecting piece 24 is provided with an insulating isolation plate 25;

[0032] Through the provided battery cells 21, electricity can be stored so that it can be discharged when needed. At the same time, the amount of electricity stored can be increased or decreased, which is convenient for adjustment when used in different devices. At the same time, through the provided extreme connecting pieces 24, the positive and negative poles of multiple groups of battery cells 21 can be connected to form a whole, thereby improving the use of the battery. Power connection terminals 23 are respectively provided on both sides of the extreme connecting piece 24 at the upper end, which can guide the positive and negative poles of the battery cells so as to be connected to the external power socket 12 for charging and discharging. At the same time, through the insulating isolation plate 25 provided on the surface, the connection point can be effectively insulated to avoid leakage accidents.

[0033] As an improvement of the above technical solution, the power supply module 2 is provided with multiple groups, and all are connected through the BMS power supply module 4. The overall length can be increased according to different devices to improve the battery life.

[0034] As an improvement of the above technical solution, the fixing seat 22 is longitudinally provided with a double array of battery cell slots to position and fix the battery cells 21, and the battery cells 21 are longitudinally staggered and installed in an extreme manner, which makes it more convenient to connect the battery cells 21 and improves the battery life when in use.
