title_body: Empty Cells on LiPo - Balance Charger or Battery Problem?
upvoted_answer: It sounds like the balance lead for the first cell isn't connected somewhere. The wire may have come off inside the charger, or it could be the balance plug, the wire, or an external parallel board (if you're using one).
  
  I'd open up the charger and test the voltage at the back of the balance plug, and see if you can spot any broken solder joints.
