Sure sounds like a bad cell.
But I always like confirmation from a second source.
Another meter or different charger.

Just for info battery was probably good, but one of the charging ports isn't pushing any current after checking with volt meter hopefully this didn't kill the the one cell will try another charger.

Most but not all LiPoly chargers do not push any current into the batter thru the balancing leads. The main power leads is how the charge gets into the battery and the balancing leads are used to bleed / discharge excess current from the cells which are charging to higher voltage than the others.

I truely hope some will use this link and read this article from years ago and get some understanding of why and how LIPoys are balanced.

This is true but for the people that are new to lipo batteries and just starting in edf's or any type of rc and bought RTF would not know this, because that is how the stock charger works I agree that through the main power leads is the way to go (link is a great help)
