1. Don't use just one word in the topic title. It must contain battery part number, chip model and short description of the issue.

2. Use NLBA screenshot button. The screenshot that you posted is blurred and unreadable.

The problem is self explanatory.

You must balance the cells.

What is not clear to you?

 Connect Regulated Power Supply to Cell 2 using crocodiles or solder the wires. Set Voltage trimmer to 3.7v, Current trimmer to 0.5a. Wait an hour until Cell 2 will be charged to same level like Cell 3. Then repeat the same method for Cell 1.

 It does show. Lab power supply has current indicator.

Do I have to disassemble the batteries to charge each cell separately? I have a laboratory power supply, but when the battery is connected, it does not show information that it is charging

 No. Its enough to access the pcb joint points to solder two wires or connect a crocodiles.

 Bring the battery to workshop so qualified personnel could fix it for you.
