Tug Posted July 21, 2013 Share Posted July 21, 2013 Unplug the balance lead until it hits 13 ish volts. Then plug balance lead back in. Quote Link to comment Share on other sites More sharing options...

DeadMeatUK Posted July 21, 2013 Share Posted July 21, 2013 Charge it as a Nimh for 3 minutes then try it again Quote Link to comment Share on other sites More sharing options...
stretch Posted July 21, 2013 Share Posted July 21, 2013 try charging as nimh at a low rate for a bit but keep an eye on it 3.71v that makes 14.84???? Quote Link to comment Share on other sites More sharing options...
DeadMeatUK Posted July 21, 2013 Share Posted July 21, 2013 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 Quote Link to comment Share on other sites More sharing options...
Cod head Posted July 21, 2013 Author Share Posted July 21, 2013 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 Quote Link to comment Share on other sites More sharing options...
stretch Posted July 21, 2013 Share Posted July 21, 2013 (edited) 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?

suicideneil Posted July 22, 2013 Share Posted July 22, 2013 It's gone up a bit since tryin to charge it that's why it's at 14.84 How about answering the questions you've been asked, assuming you actually want some help? What is the voltage of each cell, not just one? What settings are you using on the charger ( charge current )? Have you tried charging it as a nimh pack for a few minutes ( at the rated current of the pack ), then switching back to lipo mode? Quote Link to comment Share on other sites More sharing options...
Cod head Posted July 22, 2013 Author Share Posted July 22, 2013 Looks like it's a dead cell only showing 3 cells Quote Link to comment Share on other sites More sharing options...

Looks like it's a dead cell only showing 3 cells *facepalm* What is only showing 3 cells? How & where are you measuring the cell voltages? You are being completely unhelpful- don't expect to get any more help or advice until you start being a bit more forthcoming with actual useful info. 1 Quote Link to comment Share on other sites More sharing options...
