Lipo advice

[Deva]

Ed, you really need something to read the voltages of the LiPo's because that really tells you what is going on. It is very hard to deduce anything if you can't do that. The good chargers will tell you such things, otherwise you might like to get a multimeter so you can test them. If your charger is doing things 'properly' then none of yours are toast, as it would not have accepted a charge if the voltage was too low.

 

Sometimes they can be saved if the charger will refuse to charge, I had a LiPo about .5v below the 3v minimum, gave it about 10 seconds on a NiMh charge which upped the voltage just enough for the proper LiPo charge to work. Obviously there is some risk in that, they do have their own charge setting for a reason..

 

I've had some LiPo's sat around for nearly a year now on half charge and they don't really drop at all if not connected to anything. They are ~8000mah packs though
