One of the lipo batteries on a 4S mod of mine has one cell that has a lower voltage than the others and will only charge the battery to 70% of the capacity.
Here's a pic of EScribe, cell number 2 is lower.

What is the cause of that cell being unbalanced?
I'd rather avoid any further hassles
@Mooch any lipo info would be very much appreciated Mate
