Unplug the balance lead until it hits 13 ish volts. Then plug balance lead back in.

How long has it been low? I've run down Lipo's lots of times during a run and charged them back to 3.8v straight away with no problems. Problems start if left discharged for too long

It will only charge to 12 v without balance lead saying battery full ???

Then try again on balance but still get low voltage reading

It's not an old battery only had about 10 cycles

what is the voltage of each cell ie C1 C2 C3 C4 can't be 3.71 as you said as that would mean it's at 14.84v and yousays it's at 11.24v

You sure you got the charger set to 4s?
