Sounds like you have a bad lipo. I have a few myself that I have to discard that are well over a year old.
Just got two Sky LIPO 3s 3300mah 30c hardcase ones from HobbyPartz.com. Very nice case and leads. Both of them arrived at around 11.x volts and at least one cell was out of balance when I charged them. Only time will tell how good they really are.
