[NSRCA-discussion] Help!!! Lipo recovery advise requested

[Robert Campbell]

Mike,

I've recovered a couple of LiPo packs for people.  What I do is place the battery in a safe place (LiPO sack, crock pot, etc) connect it to the charger without using the balance board.  I then set the charger to NiCad and the charge rate to 0.1C.  Then I carefully monitor the voltage until it rises above 3 volts per cell.  Then, I stop the NiCad charge and then finish charging with the normal Lipo balance setting.

Rob

   I have a brand new test pack that I gave to my best friend aptly named "Puff Daddy" who tests for us. He's a great resource because he beats the living crude out of Lipo's so you can feel assured that your doing well if PD is succesful with them.
   We'll PD did himself very proud last week and discharged the 2 packs on the first attempt to 0 voltage. Opps he got distracted.
   So how can I get some voltage into the packs so the charger can attempt to recover them? I know it's not going to be a text book operation but I'm willing to roll some dice to see if there is a way. One guy suggested using a nicad charger to pump in some juice.
   At this point barring an exposion risk I have little to lose.
   So any suggestions? TIA, Mike
