[0021] A lithium battery pack with digital display function includes a main housing 1, an upper housing 3, and a side housing 4. The inner side of the main housing 1 is provided with a plurality of evenly distributed battery slots 2. The upper side of the main housing 1 is provided with a circuit board 6. The lower side of the circuit board 6 is detachably connected to two sets of battery connection plates 7 symmetrically distributed from left to right. The upper side of the circuit board 6 is soldered with a button controller 8 and a 6P ejector pin female socket 9. The upper side of the circuit board 6 is provided with a digital display screen 10. The lower side of the digital display screen 10 is fixedly connected with a flexible flat cable 11. The end of the flexible flat cable 11 away from the digital display screen 10 is fixedly connected to a 6P ejector pin male socket 12. The 6P ejector pin male socket 12 is inserted into the 6P ejector pin female socket 9.

[0022] The main housing 1 has an upper housing 3 on its upper side, and side housings 4 on both the left and right sides. Multiple connecting bolts 5 are threaded onto both sides of the main housing 1, passing through the upper housing 3 and side housings 4. These bolts lock the main housing 1, upper housing 3, and side housings 4. The upper side of the main housing 1 has multiple limiting blocks. The circuit board 6 contacts these limiting blocks, and the upper side of the circuit board 6 has an infusion limiting protrusion that fits against the upper housing 3. The main housing 1 and upper housing 3 restrict the circuit board 6, preventing it from moving relative to the main housing 1. The battery slot 2 is open from left to right. The opposing sides of the two battery connecting plates 7 are attached to the main housing 1. Each battery connecting plate 7 is equipped with a battery connecting piece. The battery connecting pieces of the battery connecting plates 7 are located at the left and right ends of the battery slot 2.

When using the device, first place multiple lithium batteries in the battery slot 2 of the main housing 1, and then clip the circuit board 6 onto the limiting block of the main housing 1. The circuit board 6 fixes the battery connection plate 7 so that the two sets of battery connection plates 7 are in contact with the two electrodes of the lithium batteries respectively. Then, clip the digital display screen 10 into the limiting slot of the upper housing 3, and insert the 6P ejector pin male socket 12 connected to the flexible flat cable 11 into the 6P ejector pin female socket 9. This allows the circuit board 6 and the digital display screen 10 to be electrically connected. Then, place the upper housing 3 on the upper side of the main housing 1. The circuit board 6 can be adjusted through the upper housing 3. To prevent the circuit board 6 from moving relative to the main housing 1, the two side housings 4 are placed on the left and right sides of the main housing 1 respectively. The main housing 1, upper housing 3, and side housings 4 are locked together with connecting bolts 5 to complete the installation of the device. The device can adjust the circuit board 6 through the button controller 8, and detect the battery in the battery slot 2 through the circuit board 6.
