Battery is toast?
Discussion
Battery is toast...? Hello Fellow fliers, battery in question is: Pulse LiPo 6s 3300mah. 65C Been in one "hard landing" ..... probably 10-15 charges total Not puffed, no outside visible damage Cell 1 is consistently 0.3V below the others. Cells 2-6 are all good and balanced fully charged 4.15V, faulty cell 3.96V Have tried balance charge, discharge and recharge and it remains below the other cells. Right now trying to balance again readungs are: 1- 3.680V 2-3.945V 3-3.942V 4-3.949V 5-3.959V 6-3.957V Any suggestions or just discharge and toss? |

You could remove cell#1 and turn pack into 5s.

Have you tried charging that 1 lonesome cell, by itself? It is a 50/50 shot at reviving it that way. I have had luck that way, and I have not had luck that way. Typically, I will just toss it away, but I will try to revive it
I had a brand new OptiPower 6S 5k pack, with a low cell in it, from the manuf. I tried all my magic tricks, and nothing would bring it back. Sent it back in, and got a brand new one back. |

I am going to try and charge that cell by itself.
Update: I did used a rigged servo lead to charge cell 1 It is now 3.96 volts were cells 2-6 are in the 3.68 volts. I've plugged the 6S battery for a balance charge, hopefully it will hold with the rest. Thanks all for your suggestions |
