- When you run your voltage down too low you damage the battery, some amount. Is that battery totally worthless, depends. If it holds it's voltage after charging back up, it could be useful in some way. It could even be used to power a model again. Then again, it could also burn your house down.

I’ve brought several batteries back with the ni-cad method. You just have to keep an eye on it. But thank you very much for teaching us this seemingly much safer method!
how to you calculate the voltage and whatever to charge it at?
!!! Nice info, thanks!!! What if it puff just a little? (really little :D about 1.5mm from both sides) Trash it?
You can check the internal resistance and see if it’s good. It’s hard to say if it is bad 100% because it has puffed slightly, but it is a sign that it’s not going to hold up for long 🤙
Great videos!!
Right on stay safe! 🤙
Thanks Chadd
I got even worse, used li po to charge my laptop in blackout and discharged to 2volts per cell, when I plugged in to isdt air 8 charger I note that the voltage slowly grows with time, does it charge it on his own without a task, meaning that charger is smart enough to understand that I am stupid idiot almost killed battery and it's trying to revive it on his own?
btw it gets to 2.5v and maybe even higher per cell on average on his own before starting charging with life algorithm
iSDT chargers will go into “Keep” mode by themselves at the end of a charge, but will not apply a charge without running a task first. I believe you are seeing the voltage rise because the battery has been removed from a load, and you are seeing ‘voltage rebound’. Either that, or the charger is giving a misreading (which is pretty rare, but is a possibility).
As stated in the video, if the charger cannot charge that battery in LiFE or Lithium Ion mode, it’s definitely not safe anymore.
@@ChaddRainsFPV yes, you are right, left them for one day, plugged and saw about 3 volts per cell, it's even enough for li po algorithm with low current, saved batteries
Telling people to not charge using NiCD, isn’t stopping them. But if all of those people switched to using LiFe mode, the hobby would be much safer.
If you disagree, explain how you would stop the NiCD “reviving” issue. We know telling them to stop, doesn’t work.
