Default How to fully discharge Lipo

So I have two bad packs that I would like to throw away. I have been discharging them with a 12V headlight and I got the voltage to 0.1V. But then after I unplugged 12V bulb, the voltage on the battery starts to increase slowly again.

I did plug in the 12V overnight and still does the same.

They're already ready to pitch. Too late to do any of the checks.

I BELIEVE this is correct, but I'm not positive:

LiPo's voltage doesn't drop as it gets closer to dying, I believe it is steady, then dead. You may want to try to just keep them plugged in until it says 0v.


Please correct me if I'm wrong.

I have a 4s pack with a dead cell in it that I have been debating on putting at a dead short from safe range, what better way to do it, right?

I smashed a 3s with a wood saw, well worth it, no fire just heaps of smoke.

But the best way it to soak them in a bucket of salty water for a week... Well that's the boring way

Yep, drop them in a bucket of saltwater for a week then chuck them in the trash. lipo is pretty much biodegradable. As nasty as lithium is, it does decompose eventually in an oxygen rich environment.

An alternate option for some of us is to take it to a Radio Shack, they will take care of it. That's what I did with a 4s pack I had - didn't have to discharge or anything, they just take it off your hands and take care of it. Quite easy.

I discharge to 0 overnight, then dead short the balance connector. Then either chuck it, or drop it off at Home Depot or Lowes for recycling.
