Restoration & MOD Electronic Scale to Use 18650 Lithium Battery, Repair Modification electronics

Restoration and modification of an electronic scale and repair of the lead-acid battery inside it. The circuit does not support lead-acid battery charging, only connecting the 5V voltage to the batteries. Therefore, I further transformed it into an 18650 lithium battery power supply, adding a step-down circuit and a lithium battery charging circuit, allowing the socket to support 8-24V voltage. The power input of the electronic scale is removed. The input voltage is directly changed to 5V to connect to the lithium battery's charging circuit, with the output of the charging circuit connecting the lithium battery and the battery input terminal of the electronic scale. The charging lamp, originally on the side of the outer case, now occupies the position of the original AC lamp. Due to the temporary lack of two-color LED lights, I polished two LED beads and stuck them together. Finally, the battery compartment is expanded to accommodate four 18650 batteries. After completion, plugging in the 8-24V power cord will turn the AC lamp red if the battery is low and green when the battery is full.
