battery trouble -
11.11.2012, 02:16 PM
Ok all, have a 1 cycled GensAce 25C 4s 5300 lipo....one cell appears to be dead after one charge...
 I am using a hyperion charger 615i duo 3. How can I try to recover that one cell? IT's not the balance board as I am charging a 5s as we speak. Tried changing boards with the same results.

Have you tested the individual cell voltages with a volt meter?
You could always try to charge as NiMh and see if the cell moves up. |

I assume this is a newly purchased pack ?
Call Hobbypartz because they will replace it ! |

I would do as Bondo suggests. I haven't dealt with them yet to comment but if they'll replace it, kudos to you and them.

3 cells at 5.1v? that's really high and I wouldn't use it at all. I'm going to assume you meant 4.1 though.
You can make a jumper to charge the individual cell through the balance tap. But I would say a cell that low is trash. I've saved them from like 2.5V, much lower than that I'd be worried. |

Brian, If the pack is new don't even mess with it. Call HPz and they'll give you a RO# to send the lipo back with, if the packs are in stock turn around is only a couple days.
If one cell is dead and another is 5.1 my guess is there's a jump between 2 cells somehow ? |

Can't be 5.1, the charger wouldn't allow it, and it would have blowed up.
It's "Dr. _paralyzed_" actually. Not like with a PhD, but Doctor like in Dr. Pepper. |
