Machine breakdown. When the user uses a single lithium battery for power supply, the 14-pin chip of the power display is caused by machine failure. It only needs to go to a professional repair shop for repair. Lithium battery is a type of battery that uses lithium metal or lithium alloy as positive/negative electrode materials and uses non-aqueous electrolyte solution.
This is a lithium battery charging chip
