hey, so my battery has 2 wires sticking out of it, a positive and a negative. Am i allowed to just drop it off in a battery recycling bin? I'm scared it might still be charged and hurt someone if something goes wrong.
Hi, halogen light bulbs seems an interesting method and I like to build small electronic project !! Resistor vs halogen light bulbs ... do you think a method is better than the other one ??
So say someone lost a 3s 1000mah lipo in their basement after they drained it down to around 3.1ish volts on a run about a week ago and is internally freaking out that their house is gonna burn down in the middle of the night. Is it probable that the battery's gonna burst into flames if the voltage gets too low and if so how long till it does? I'm asking for a friend.
At 3.1v, it's probably not strong enough to cause any damage by itself. If the internals are damaged in any way, they could spontaneously combust, but again, at 3.1v it probably wouldn't amount to much. There's certainly no way for me to predict how long a damaged battery will remain volatile. Now if a bunch of flammable material were sitting on top of it when it let go, that could wind up on the news. Your friend should probably get busy and find his battery.
@@RCVideoReviews nah, my little buddy passed about two months ago, he was good about leaving stuff be. Only thing I could think of would be that it might have been mixed in with some packaging on my desk and probably got thrown away. I'm pretty sure wherever I had left it i saw it and a little voice said to charge it and put it away but I didn't do it, I also seem to remember it falling in some God-forsaken crevice and I told myself I would find it later. Rip. I'm not too concerned about cells and stuff not discharging at the same rates because I've left it for a few months (in my lipo bag) forgetting to charge it before and they were within about .7 volts of each other. Still something I don't want to leave laying around tho, cuz there's a high change a tool or something else could get dropped on it
PLS what resistor would you recommend for discharging two 3s 5000mah at once? (so either 6s 5000mah if in series or 3s 10.000mah if in parallel) I have few very puffed pairs I need to discharge for disposal I don't want to discharge them too fast and put too much strain on them since they are already very puffed....something safe I can keep plugged in overnight (outisde in a lipo bag) and it will drain them within few hours also please state if the recommended resistor is for series or parallel, thx
Thank you very much I used 2 old ceramic resitors in parallel to go faster and it does the job : 2 x 10W 2Ohm.J The last 200 mV on this 2S 2200mAh are long .... Puff puff puff
Awesome! I just take my old batteries to Batteries Plus, they have recycling bins too. But I was waiting and watching actually HOPING for SMOKE! Haha haha 😂
You can find a lipo killer for next to no money. It's so very cheap to buy a resistor--it is literally the cheapest thing to do. Save your $$ and get one.
I have a 3 cell battery that isn't no longer a 3s lipo it's become a 2s and doesn't want to discharge and I want to dispose of it properly what can I do?
Connect the mains to a load just like this video shows. It doesn't matter what the battery wants. A load will drain the battery. When you read 0.0v on the mains, you put it in the trash as it becomes inert.

Halgoen lights get really really hot and you're not supposed to touch the glass because the oils from your hands can cause the glass to break.
@@RCVideoReviews Really good to know thanks

@@RCVideoReviews he says thank you and he'll get to it even though he's moved and reorganized everything where it should be two times already 😬
Yikes! It's probably not in the basement then. Did the dog get hold of it?

What is the thing you are using to discharge it? I am trying so hard to figure out how to discharge it to 0v for disposal
. All i have is a hota
It says on the video when he's Plugging it in "6 ohm 100w wound resistor"
Thank you very much

Nice work!

Ohhhh...that ship hasn't sailed yet...
Very great info and just subbed
Airbus737 welcome to the channel!
Just noticed after discharge battery that way voltage read is 0v, but individual cells measure as 0.8 and -0.8. That interesting.
I decided to go ahead with discharging individual cells via balance plug. Seems to me it is safe.
Fun to watch. Good to know.
I get asked this question *a lot*. Good to hear from you ;)
And what if we don’t have those tools and the Lopo battery is swollen everyday then what

@@RCVideoReviews I tried to discharge the battery with my lectron pro charger but won't let it use it because the 3rd cell is not working.
You have to use a dumb device like a resistor.
@@RCVideoReviews I need that because I have one lol
@@RCVideoReviews i buy a "testload" from ALI
Why the extra minute and a half of Black screen at the end?
Not sure. Something got by on the final edit. I'll try and trim on YT.
What resistors did you use ?
I started with a 6ohm100w and switched to a 2ohm100w.
What about restoring DEAD batteries?
If you run a lipo to 0v, you need to retire it as there is permanent damage to the cell. It's not worth the risk trying to recover.
You should have put it in the salt bath.
Why? This method works just fine. Salt baths have been shown to not be 100% effective.
I don`t know what i`m doing, but i know how to do it.
Well then you're ahead of the game.
Now revive it! 😅
Lol. That one is dead Jim!
Well.....,. It's dead.
Yessir, it is.
🤣Awesome video
Thanks. I had to goof off a little in this one because the material is kind of dry. Glad you liked it.
😂
Glad you found the humor :)
