Incroyables Expériences bad things about lipo: too fragile that even note 7 blows up itself

Bon de vous voir ici !

Bitelaserkhalif 555 That's because they did not add the proper battery protection circuit

DarkSlayer 1411 no the problem was battery itself

I think Note 7 is liion, not lipo.

Well for that i may not be so right but once i charged my diy lithium ion battery fan and I don't know how i lost it .but after one and a half month i found it and it gave me pretty much the same backup it usually does . Don't know it might have lost a little bit of energy.🤔

Same. that is genius.

The life is so simple, sometimes ;-)

this is probably the most helpful thing i've never thought of. always have trouble with this, just so happens i have a stack of mini neo's right next to me.

I had it in mind for a long time but I was wondering is it actually safe/recommended to run electricity through a permament magnet? I couldn't find anything about anyone even attempting to do so on the internet so I figured there is some issue I am not aware of (and that is probably too obvious to even mention it), hence noneones uses it this way and was the reason why I couldn't find anything. Could someone shed some light?

I think the magnets have a moderate 0.5-2 ohm resistance which makes them okay for charging small batteries

***** yup. Sounds about right. There's also Li-Fe (lithium Iron), which is pretty low power (mine is 2A max).

+kingknut icr, inr, imr all meaningless really, as no standardisation amongst all manufacturers in this regard. High discharge "li-po" in an 18650 package are being called "Ii-ion", and low discharge "li-ion" in a soft pouch is still "li-ion".. Go figure!!

***** Well, they're good for RC transmitters because they're low power, and don't need to be set at a storage voltage. Like all batteries, they're fit for a specific purpose.

Unless their from certain online hobby store... Their cheaper transmitter packs have been known to puff when left charged.. Probably reject cells rebranded, might have a tiny bit of iron in the recipe so marketing calls em "li-fe".. ni-mh Eneloops are great for tx's

Good review. High discharge current is also important.

Yeah, maybe

how can you measure the charge efficiency?

@@antkoos Congrats bro, you just dug out 3yo comment. Anyway, you can just measure energy "pumped" into the cell when charging, then measure te energy sucked out of it and compare the two.

They all work forever, just repair it if it breaks then you have infinite charges

In terms of charge cycles, Lead Acid is weird in that there are 2 types of batteries with different ratings. "Deep Cycle" batteries are made from solid pieces of lead and can be fully charged and discharged many times, whereas "Starting Lighting and Ignition" batteries are made of lead sponge and can degrade rapidly if fully discharged

You're welcome ;-)

And NiMH is ot so bad in cold either and can be charged in cold conditions too.

Lithium ion batteries perform better in the cold most cars that don't start in the winter are stuck there because their lead acid batteries failing.

Yes bro acid lead battery is best

👍👍

I like your ideas, but this is a weekly show produced by one person. I can not put that much into one video.

What Tony Shulthise already said is also in my view of interest! Take the time you need for the video. It would be pretty helpfull for my portable solar devices :D And, nice Video! :)

GreatScott! I didn't mean to imply that you should do it. Sorry if it sounded like a complaint! I was just thinking about all the times I've needed all that info and couldn't find it in one place, even on dedicated battery info sites. This was great information and thanks for all the time you put in to sharing great videos with us. I always look forward to your videos. You really do a great job.

This was a great introductory video, clear and concise. Having all that extra info and comparing all those extra characteristics would make the video too long. Sure, they are useful but after this introductory video the user can go and research those extra parameters on it's own after it has narrowed down it's battery selection.

Hi guys, what module can I use to make a 10000mah Lipo battery pack ???🙏🏽🙏🏽🙏🏽🙏🏽

Depends who you ask. I think in his field he uses Wh more than J

Because J is the correct unit of energy, just like m is the correct unit of length. What else is there to say?@@user-kx8vn6tm1d

You're welcome

Woop Woop GreatScott Video out on my B-Day! so lucky :D Thanks !

@@greatscottlab I want to use 8 Aa batteries alkaline or should I use nihn 1.2v 1200 mah battery it is £8 pounds for 8 batteries and should I use 1.5v zinc batteries I get 30 batteries for £2 pounds or should I buy alkaline 1.5v batteries AA but I have a problem is the head of the batteries and I am draining at 2A and alkaline can only be used at 500 ma to 1A so I am losing capacity I think my 1200mah 1.2v AA Rechargeables can do 1.2A for one hour or maybe 2.4A for half an hour or should I buy solar panel but it always seems to rain down in Scotland but when it's sunny it get to about 30° outside but the solar panel was going to spend about £60 pounds for the first time projects

Maybe, maybe not.....

+GreatScott! i will help you. :)

Kauza Mohlamonyane I wanted to write exactly this;)

+Jojo I guess I beat you to it😉 maybe you will remind him at a million subscribers

+GreatScott! That means yes (at least for me) 😜

I too would like to see something like this. Seems right up his street =)

Mine too and ni-cd's

doN't they emit poisonous gasses when overcharged? how do you decide whether they are charged full or not in a typical lead acid powered Flashlight?

@@landingonyuranus1813 no, they are most likely closed and if yes then very small amount

Mine too

@@landingonyuranus1813 Not poisonous, but flammable: overcharged lead acid emits hydrogen gas from what I remember.

Cody Even if he made contact the battery would not have exploded instantly. Happened to me once and I just dropped it because of the terrifying spark, nothing happened.

BMicraft yeah I was exaggerating I've done it too made a tiny little Spark

BMicraft Same here, although I accidentally shorted a 5000mah 3s lipo on a cheap screwdriver. It makes quite the impressive blue spark...

Not all people can obtain latest tech due to price or availability, especially if we're talking about energy storage devices. We'll wait for an update to this video if it becomes mainstream enough.

samsoulee i was curious about NI-CD vs NI-MH

LiFePO4 is not latest tech. They are more stable than the other Lithium chemistries and perhaps a bit lower energy density and current output, but far more useful than lead acid chemistry batteries. I have 180AH at 66v in my electric vehicle and it beats the daylights out of lead acid. I expect I will die long before the pack does.

lifepo4 is not latest tech, it is widely and easily available, and mainstream.

LiFePO4 is nice to power 3.3V electronics because its not need a voltage regulator. The decharing vs voltage is also very nice on LiFePO4

Why they not made of copper?

@@ddd228 have you ever seen a magnet made of copper?

@@TheNamesArif Well....NOPE!

i dont know if you guys know that but sam died in glider cocpit. r.i.p sam

@@arclike255 what you mean the guy that commented ?

Pros and cons between Batteries and Capacitors. Batteries typically have higher energy storage. (often millions of times larger then that of regular capacitors, and still thousands more then Super capacitors. (when comparing capacity/wight and capacity/volume, or even capacity/cost)) Capacitors also typically have higher self discharge then batteries. (except capacitors built for low leakage, but those typically have really low capacity) Capacitors are on the other hand are typically not having a charge/discharge energy loss of more then 1%. While most battery technologies have 30% or more loss. Put in 1 W/h of energy, and expect to get 0.7 W/h back out, while capacitors are giving almost everything back. Capacitors are typically also generally better at high current discharge, and 1KA+ isn't too uncommon to find in both regular capacitors and in Supercaps. The reason for this is that they are relying on a electric field, instead of chemistry. Capacitors are normally used where one needs to store energy for a short amount of time, while batteries are used to store energy for longer amounts of time. All in all, capacitors are typically used in areas where one needs a small amount of energy storage, or really high current discharge. And typical applications are as follows: Bypass capacitors in digital/analog circuitry, as to mitigate voltage drop in PCB traces and cables. Bulk energy storage in PSUs, to make sure that they still operate between mains cycles. Backup battery for RTC and SRAM, (this was typical in older equipment for storing calibration data, or other information, these days a watch battery is more typical.) Defibrillators use high voltage capacitors, as they give a faster discharge then batteries, and that its safer in the factory to handle an uncharged multi kilovolt capacitor bank, then handling a battery with the same voltage. Some cars that have electric motors sometime implement a smaller capacitor bank for regenerative breaking, and also to have less energy loss from charging/discharging batteries. And some windup torches have super capacitors to store the energy, as batteries are heavier, and have around 30%+ energy loss. Long term energy storage is where batteries shine, and capacitors are typically for short term. I hope this text wasn't too long...

The biggest advantage of caps is that they can deliver instant maximum current up to 100 amps and more....

And the biggest disadvantage as an energy source is that a significant portion of the energy is available only if your circuit can accept a small fraction of the fully charged voltage.

lead acid holds up the best in extreme temperatures.

No Iron Edison batteries do!

How about NiMH? I've had experience with Li Ion failing in extreme cold, so I know that's out of the question.
