AND ALSO DISCONNECT THE PARALLEL & SERIES CONNECTION OF BATTERY PACK (CLEAN THE SHARP EDGES FOR SAFETY)

Step 4: CHECK THE VOLTAGE OF CELL

JUST CHECK THE VOLTAGE OF CELL WITH MULTI METER OR ANY OTHER

ABOVE 3 VOLTS CELLS ARE GENERALLY GOOD .

USE THEM FOR YOUR POWER BANK

Step 5: INSERT CELL INSIDE POWER BANK

JUST INSERT OR SOLDER CELL INSIDE POWER BANK WITH CORRECT POLARITY

You took cell of 3.5v only , does it charge mobile ?,,,,

Yes ,
It will surely charge
But how much capacity of cell is different question
Which can only be known by capacity testing (which you can find on my YouTube channel WAQAR Alam)
