This is great I'm 61 and this stuff is better than anything we had in school back in the early 70s. Except for a few well developed young ladies.. :) >
I've been doing this for quite some time, and as other posters have pointed out your mileage may vary. Very often, laptops are thrown out with perfectly good battery packs. Or packs like you have shown here appear to have legitimate cells. As other posters have also pointed out, these will not work for vaping because the instantaneous current output of even four cells in parallel is maybe 2 or 3 amps at best.
Stop cutting off the wires at the cells (you need those) and keep them as a matched set. Buy some real balanced LiPO chargers and do some real world testing of each bank of four to find any bad cells packs. If they all match in capacity, then label them and keep them paired together. Add another set of 4 in series (of equal capacity) to the first three sets, and you have the perfect stand-in for a 13.65 Vdc Lead Acid battery for backup or larger banks. You will need buck regulators for this.
The important thing to remember is that those series sets of 4 are Matched Sets from the factory, and should be kept that way. Once you separate them from each other they can no longer be used that way.
1) Plastic box opens better from the middle seam;
2) Do not remove the isolating [white] ring at the positive side of the cells. Sometimes the metal that shunts parallel cells damage the isolation and contact the nearby negative shell starting a fire. The white ring helps to avoid this.
Thanks for the tip on the Batteries.
Bread of Life More than welcome
You are amazing.Thank you
i like how these laptop batteries look so elegant and intricately engineered on the outside,but strip away the plastic shell its just a bunch of batteries and wires and a circuit board taped together haphazardly with scotch tape by some 17 year old in a chinese sweat shop.
I can make better battery pack , learn more pls contact me .
Just out of curiosity, did you check if you shorted 1 or 2 cells from the first pack? Because the only reason you got 3.75 volts at 7:41 is because you did so while they're in parallel. Good presentation none the less.
Nice to see some good recycling .
Yes, I think it's important to recycle and reuse. These batteries are good.
these 18650s are rated 3A for lighting ? or
30A for high drain high discharge (for motor) ?
Es increíble lo relajante que me resulto tu video, muy interesante gracias (tuve que escribir en mi idioma nativo por que me dio mucho sueño, me ayudó a superar el insomnio de hoy)
I saw your video after I received and opened my laptop battery. What a coincidence that you bought the same batteries! Only mine were really hard to open and stuck with silicon to the casing...I had the smoke thing too, but everything seems ok.
Best of luck!
+Andrew Jones Thanks!
+jsboyYAug was probably a wire burning after being shorted, i have burned some of the pcbs by shorting then while cutting the wires with scissors.
Finally someone explained the stupid wires of laptop batteries thank you man. Life saver. I just need one answer it would help me a lot as I transformed the laptop batteries into my old drill. Now say you took the laptop charger wires and plugged the plus and minus as it is right now would it charge the batteries or do you need the normal way thru the lap top to charge the batteries? So the question is does it matter how I charge the batteries as long as the pc board is connected as it was for the laptop? Please explain much helpful. Thank you 😊
Thank u sir u good video sharing
Nice Work Andrew,
WhidbeyAutomation Thank you very much! :)
So what is the amperage of these individual 18650 cells? Does anyone know? Because I have a few and wanted to know if they were safe to use in a box mod. Any information on this would be really helpful. Please and thank you
Hi, i have 48v 50a motor, this type of battery canot give 50a all time ?
very cool :)
I'm not really worried about trying to find cells, I'm very interested in finding the right BMS. Does anyone know where to find good DIY solutions for BMS?
warm the pack up to 45°C en the glue is soft so the caching opens much easier.
Gloves. Wear gloves when you're cracking cases. I've broken hundreds and sliced my fingers way too many times.
Now that you've removed the BMS you'll need a way to balance charge each cell.
I've found a way around that if you're interested.
Any "glued shut" cases are a lot easier to open if you crack the ultrasonic weld with a fat chisel and some medium-light taps from something like a heavy screwdriver handle. "tap tap snap" then repeat around the whole edge and the case splits with no prying.
I have a device that will run on 8v ~ 24v and I want to come as close as possible to 24v so if I took two of these apart and wired the other one in parallel I'd have 22,2v, but how would I safely charge these to 22.2v or 20v without having a explosion, please?
after removing all cells from battery it does not work and i joined it in parallel way?
notebook batteries are good source. fujitsu batteries 10.8V 5200mAh (3s2p, 2600mAh per cell) you can get "new" for 15EUR, it contains 6x 18650 relatively good quality cells, thats 2.50EUR per cell.
Very usefull video
Mad man
Dear Andrew, would one of these battery packs be sufficient to power an electric skateboard motor? 2500Watt 80Amps max volt 12S
I've found an awesome way to get the 18650 way cheaper. There is a site that allows you to get free/discounted products on Amazon in exchange for reviews. They often have random laptop packs for around 5 bucks. I get the packs and am still able to put out good honest reviews because I can see what cells the packs are made from and the internal solder/component quality. I have a collection of about 40 18650 all mostly LGs and I paid around $25 total
Forgot the site, it's called AMZREVIEWTRADER
your channel picture... in the first moment you look like "Stefan Raab" a german comedian :-)
Those "sensors" you were testing are called Thermistors. Cheers!
Nicely video
Never stack or let 18650's that have damaged plastic casings contact one another
Like most packed rechargeable batteries, the entire surface of the metallic canister is the anode
You can easily cause a short of these batteries when the are still connected to one another. Especially so when in series configurations of any kind.
Not only would you likely get inaccurate readings when testing them like you did, you may also damage the cells, and obviously, if left unattended, you could start a fire, but I'm sure you knew most of this, so consider this comment to be more so for viewers.
+Hydranix HNx They're reletivaley safe if laying stacked side by side, but end to end is another story....
How is your project go cart going?any progress? thanks
For safety, use temp-controlled auto switchoff, or thin wires as melting fuses if you prefer to keep it simple. Isolated from the cells of course, or it would be even more dangerous. You just got yourself a new subscriber, and a fellow mad scientist at that.
I honestly cannot believe the price per cell you got. Well played
+Anton Shorter the problem is you can buy them for $1.25 CAD each on ebay,even better in bulk ($75 for the same amount here) , this is not a way to get a savings, unless you buy used laptop packs that wont charge right cheap, and separate the one cell that usually goes wrong in one of the banks of cells , also if your building an ebike or electric vehicle you need to test each cell individually ,not just each bank ,if you dont that one cell can prevent the whole final pack to not charge right
not an issue here with new packs of course
very nice
I know it is a bit older video now but I noticed you did not seem to consider the electronics inside the batteries much. My question is if that electronics could be used when putting together a big battery using the notebook batteries as they are. The notebook batteries are designed with safety in mind, so the charge and discharge rates through that electronics might be ideal. So could you just hook up many notebook batteries to create one big 10.8V battery?
nice video.. but I cringe each time I see you remove one of those washer shaped insulators from the positive side.. it's there to guard against the positive tab shorting against the negative case.
What a lot of folks dont grok is that laptop batteries are usually of higher capacity than the cheapest of the cheap ebay ones. For ultra-cheap/free batteries you can take apart discarded battery packs.. they often only have one bad cell.
Agree, Luckily i work in an IT support job and collect all the dead batterys from old laptops before they go to scrap. Have around 40 batteries at the moment most with Sanyo/LG/Panasonic cells. All for free!
fn0rd99 ... me too. I looked for it to start smoking when he tapped the buss bar down afterwards
you are awesome
good work AJ !
how did the project go ?
thanks
I want a link to buy small red pliers
can you give some tips for buying cheap batteries like yours?
These CJ 18650's make a big explosion if you charge them and throw them in a fire because the safety vent never works so the cell ruptures
Nice video man...
But I realy don't think that those 18650 cell will give you the amperage you want for a go-cart motor...
Those laptop cell are designed for large capacity, not big discharge current delivery...
You will have to parallel a lot of cells together to get the high current you need for a DC motor that can power a go-cart...
Not to mention that those cheap replacement laptop batteries contain cheap no-name 1850 cells from china that are quite sub-par some times.
Did you find any name-brand cells inside those packs?
Hi Bill. You are partially right, the batteries are no name but due to their weight, I can tell they are decent quality. Though until I actually test them all, I'm guessing they are around 2.2amps each. Tesla car batteries are made from about 7000 x 18650 batteries configured as one large cell. I'm making a smaller version of this for now. My son wants to assist me, so we are probably focusing on the frame design for now as we are still gathering batteries and powered wheel hubs. I have even thought about reconfiguring the hubs to create a main drive motor to focus all the power onto one axle. Though will go through all of these decisions in my videos. :)
Andrew Jones some of the 1865 batteries are capable of pushing 30amps I don't know if that's the case with all though.
+Andrew Jones
"Tesla car batteries are made from about 7000 x 18650 batteries configured as one large cell"
So you mean they are not in series? Whould you like to clarify on that? :)
+Andrew Jones There are so many varieties of 18650 cells, there are even cells that can do 100+ Amps for a second or two and 20-30A continous, but this is sacrified by low capacity. On the other hand even "low current" 18650 cell can supply a lot of power, it will just sag and heat up quite a lot.
+ECN both series and parallel
Any updates on the go-cart? Cant seem to find alot of info about it other than the crude 3d image video, thanks!
I've actually taken the concept from land to water of all places. I am surrounded my lakes... Everyone is doing electric powered cars etc, and I thought I would mix it up, by switching plans to a Boat instead. I actually begin making is shortly after I finish my current project in a couple weeks.
Thanks for replying, i shall look forward to future updates :D
RaygrHD I just bought the motor and buying wood next week, video series coming. I'm very excited to say the least. Hehe
Awesome man, good luck with it! I'm actually shopping around ebay for some 18650's to make a small portable power bank. Will most likely pair with a pure sinewave inverter!
RaygrHD that sounds cool! Let us know how you get on. :)
does it even come close to the rated capacity? usually all those cheap 18650s fakes the actual capacity.
These are LG cells and they are typically very good. These are low amp discharge cells, though, so only good for certain applications.
But what about the amps? aren't these suppose to provide only 2amps?
yeah they are not designed for high drain... this will be a problem
I guess it is possible, if you have enough parallel connections
if u draw 1amps for each cells in parallel then it would be ok ithink..
What happened to the first battery pack? Short it out with the paint scraper?
No, it was 20 years old and no longer working
the meter has a k in front of the ohm icon so you are measureing in Kilohms so X 1000
How many batteries would I need to make a 36 volt battery pack for my ebike
40 in 5X8 series like in my youtube video.
Is that Alabama 3 i hear in the background? A3 they call it here in the US.
Did you re-use the balance charger circuit that came with the laptop battery packs you bought online, to charge your go-kart battery pack?
that balance charger is good for nothing, it works only with the laptop motherboard
WTF /the Batteries on my dream !!!! zzzzzzzzZZZZZZZZZZ
good
btw the plastic dipped object you call a sensor isn't a sensor at all. |IT's a thermistor which is a special type of resistor who's resistance changes with temperature hence why you could see it drop in resistance.
Steven Choi Exactly. The manufacturer puts those in so they can monitor the heat. A bad lithium battery will heat up when overcharged and can blow up.
Steven Choi That is what a sensor is, usually a thermistor or photosistor.
Giuliano Damiano thanks for pointing that out, That is why I didn't bother explaining to him, since I could see for myself that is what it was.
Awesome video!! I never comment but this was great!! Thank you keep up the good work!!
Hey Some Kid! Thank you so much buddy. :)
hey I see your a fan of the 18650 i have a Reactor brand battery pack 12000mAh cap output is 5v 2a-,18v 3.5a I have run my boat motor off it for an hour. I was wondering if its possible to build a larger battery pack so I have an extended run time. say 4 hr without the heft of a full sized battery. to this I would run a small solar panel to help keep the battery charge. is this possible or am I a uneducated moron?
why not just build a voltage bus that use the Toshiba pack connector - that way, you don't need to remove the batteries out of
the pack.
+John Pham impractical, porr design, complicated, and you need to have all the pins hooked up to a laptop computer for it to process the pcb. also you would be limited greatly in power, maybe 5 amps.
I notice when you go from 9 to 12 the may drops 9 you get 2600per best I've found cheap 7800 packs
its 10 k ohms not 10 ohms it quite clearly shows this on your mreter, it looks like you did well on these batteries given that all are at a similar voltage i would guess you got new old stock rather than used and kyleg001 is correct you need to be careful what current you draw from these i would maybe rig up one of those temperature sensors and keep it under 60 deg c on discharge and 45c on charge and ideally above freezing on both counts
Did you ever make the car ??? Just made one myself and been trying to find some decent content on what other people have done
what is the price of the battery pack?
Oh Andrew, put some rubber gloves on if your gonna mess with those things. Always taking stuff apart. And cut the black wire first.
00:07 danger spicy cells
These batteries have to be charged with certain amount of amps to hols charge cause I 've built a small regulator to charge these types but does not hold charge long?
A tip is to take the capacity, divide it by three and charge it at that rate.
So if you have a cell rated at 1000mAh, you will charge it with 0,333A.
This is a good way to keep your batteries healthy for a long time :)
Hi Hampus thanks for your help. I am trying to charge 2amp batts ok with a lesser rated amp 400ma but they are not holding charge for long. Is this showing that these batts are bad? Thanks
Have you salvaged them from an old device?
Yes from a laptop computer.
guruji243 Okay, was the laptop (Or atleast batterypack) old? I kinda need to know this to find an answer.
You said you never found a bad cell in all of those battery packs, but you always measured them when they were wired in parallel with other batteries so you wouldn't really know if one was bad.
David Leigh All have been above 43gms so far though have yet to test individually for true amphours etc
+David Leigh parallel doesnt matter, if one cell is bad it will pull the others down too
i have got these CGR18650CE batterys, each cell gives a charge of 4.1 or 4.2 volts, howz that possible coz lithium ion batterys gives 3.7 volts?
thank you, but they can give more current then lead acid, what i mean is that i can run a motor of 24 volts and 50 amp by these batterys making them a pack of 24 volt 200 AHr battery pack. that wont damage the battery?
+Parasar Bhattacharya as long as you dont exceed 1c continuous or 2c peak
thanx
Nice video. Interesting and informational. Thank you for having your background music in the actual background, as so many others make it too distracting for my autistic ears.
According to your ohm meter, those thermistors where reading a little over 10K ohms or 10,000 ohms...
Thats 10 "KILO" Sherlock Ohms.
So far no luck i took apart a couple of laptop packs but the cells were dead.
I buy mine new from ebay. Though have not for while. Typically, you'll get a few cells good on old packs.
I had a massive incident trying to charge the batteries directly plus and minus went wrong big time.
would this void the warranty on the battery pack?
uh, yes.
I'm sure the cost of batteries are cheaper than breaking a perfectly good laptop battery.
Where is a good place to buy recycles batteries?

I have found the un branded ones to be garbage 9/10 , the Sanyo and later samsung ones are really good.
+Gavin FreedomLover also much more expensive, which is a bummer. But i guess its better than having a cell randomly fail, burning something up.
+Gavin FreedomLover also much more expensive, which is a bummer. But i guess its better than having a cell randomly fail, burning something up.
If one battery goes it will drag a whole row down with it
+Gavin FreedomLover I tested the cheap no name pack cells to give about 1500mAh, brand new, 2 months old. That's like you said, pretty bad. An 18650 should be 2200mAh if anything, so those are pretty poor quality cells. Slightly better than Ultrafires that give you 1000mAh at most though. Not good for MODs since you can't have a bad cell blow on your face. I also recommend Sanyo, Panasonic, or LG. I've been using the LG 3500mAh and it's doing the best for me, lowest internal resistance, and the highest capacity of the bunch. The Panasonic 3400mAh is slightly behind it, but only by about 5%.
hey mate , Yes the Sanyo red ones for me with the purple top ring and also the samsung pink ones are pretty good, how do you test the mah mate if you don't mind me asking?
Peace
How do you charge it :(
Hobby charger 20$ ezpz
Can this batteries be used for vaping purposes?
Angel zuñiga These are 18650 batteries I am working with, so yes for many of the vaping units out there so I hear.
+Angel zuñiga as long as you dont exceed 1c continuous or 2c peak
+Angel zuñiga I would not do that...Really do not want one of these blowing up in my face. Buy a good battery of known origin from a quality vendor. Do not want to blow my face off to save a few dollars.
wheres the follow up of this project
So you get 12 batteries out of this, totaling 8800 mAh .. that means each of these things holds 733 mAh ? And not only do you pay 1.60$ for each but also screw around with it for half an hour ? Can you explain to me again what about this is cheap ? Considering you yould either buy 3000 mAh batteries for like 3.50$ or work an hour and earn like 20 bucks ?
I found a lot of these 100 ICR 18650 Batteries 3.7V for $255 including free shipping on ebay. Normally $320. I'm guessing they're the same, "CHEAP" is the operative term here. THIS IS NOT 30A HIGH DRAIN TYPE! THIS IS 2C(4A) STANDARD TYPE.
PLEASE MAKE SURE YOU BUY THE RIGHT BATTERIES. -PKCELL.
If these batteries are for a laptop then they're right for his build, he seems to know what he's doing. Most everyone else who builds these batteries use the green 18650's from Panasonic. They're $4.50 a piece in a hundred lot from neobatteries and they're what Tesla Motors uses, 2 billion of them. These batteries he's using must be "High Drain" and the color is confusing me. I'm on Andrew Jones side now. Buy the laptop battery cases when they're on sale and bust into them.
TrustInJesus111 exactly how I do it buddy. And will continue to, just like hundreds or battery makers for various projects.
Andrew Jones I used to develop land for mobile homes. I had the transporter, a tractor-trailer rig and bottle jacks and piers & pads and would tear down transport and set up homes. I'd hang and take down the axles, put the wheels on etc. I had to go to 3 different school districts to pay school bond fees, and the permits, oh man, what a flipping hassle that was, soils engineering reports. I know you didn't need my support, winners don't acknowledge anyone who tells us "no, you can't do that" it sounds more like a challenge to people like us.
TrustInJesus111 damn, that's a lot of work. But I'm a high school teacher, and I had no idea just how much work that was. I'm presently building an electric 8' long boat. I'll have a self made battery pack, plus a backup marine deep cycle battery also. Looks like this 18650 battery debate, will be here for quite some time ;)
Andrew Jones Hard work is the anointing of the Teacher. Being the son of a vice admiral I had boats and owned a jet boat at the time my Dad gave me his two boats. A 16' Hobie Cat and an 18' Glastron Bow Rider. I've been ordained a long time and always got passed over for promotion in church but I took all the Christians out to the rivers and lakes and taught them how to sail and water ski.
You knew (18650) and I didn't. You can see how I was commenting that I wasn't sure. Now I know. It looks like my bike's battery is off the market, I'll probably have to do a battery build one way or another.
nyxsilver8@gmail.com is my email. Drop me a line and I'll send you enough soap to last a couple years.
Dude, you gotta be more carefull with those cells! they may be safer than li-po but they can still explode in your face
dont leave live wires hanging (cut them first!), and be more gentle
allways look at the ends of the cells to make sure youre not getting the wrong ends together
+OutLawE-Rider as long as you dont exceed 1c continuous or 2c peak
ah Andrew, these chinese batt, provides a nice discharge rate? have a "normal" capacity?
I'm testing to see how well they perform. I'll place the results in the next battery video.
+Pedro Bermudes as long as you dont exceed 1c continuous or 2c peak
This hobby will Nickle and dime you go to unitpack 50$to100$ batteries
Ahh yah Duuu 3X 3.7v (series)= V1+V2+V3=3.7v+3.7v+3.7v=11.1v hence the label 11.1V this is a 3x4 bank setup so in parallel Vt= Vb1=Vb2=Vb3=Vb4 or 11.1v
Think how it would be without the "music?" couldn't hold out til the end sry.
When I got a few dollars in my account... odd you don't sound like a 'Merican, do yer boy!
;)
"OH ANDREW... do be careful!"
rip them apart fast
An interesting video, but why put the repetitive, distracting music track on an information piece? I couldn't turn the sound down to avoid the music because I wanted to hear your commentary.
Sorry. Can't please everyone.
Thanks for the good-natured reply. I realise that most people tolerate, if not enjoy background music. But for me the question is 'does a music track add value to an instruction / information piece? I find it very distracting, but it's a commoplace that many students listen to music while studying, I couldn't do that. I like an empty room, a clean desk and silence. [This probably points to some well-defined clinical condition I suppose. Oh dear :-( ]
lol, i saw new laptop batery , 12 cell 36$ 10.8v/8800 mA

tells how to remove lithium
please
you can't. lithium ion cells don't contain lithium in pure metal form. for that you'd want AA lithium batteries
This is what I vape on. Do you even 4000 watts bro?
this comment made my day. also came here looking for mod builds?
+satoma satomis i think he might be using coils made of rebar.
10k ohms
Or buy them for less than $1.60 on Ebay...
This is really cool but why not just buy 18650s off a site in bulk for cheaper?
I'll have to see who is cheapest. But I like the thought!
illumn.com is fantastic
neobatteries.com/index.php?route=product/product&path=171_172&product_id=274
Samsung 18650-25R lot of 100 @ $4.50 each (Shipping extra). The site (Neobatteries) says they're for E-bikes and warns of knock-offs (Fake capacity). Andrew, I just don't like the color of your batteries
TrustInJesus111 I'll check Em out. I just use what I have without issue as of right now. I do need to buy more though.
Andrew Jones My Ancheer E-bike came a week early. I took my dolly (walked it) over to the UPS store and put the bike together. It only took 3 1/2 hours to charge the battery and I went out for a night ride. People like you on UA-cam have changed my life. I can electroplate quarters making them copper, do a decent balloon monkey, and I make soaps and candles like nobody's *_business._*
I've been wanting to make one of those infinity mirror boxes like the infinity hallway floating candelabra portion of the Haunted Mansion ride. I just figured out tonight how to use a mirror I had on hand with my dual glazed windows. I've been putting on a light show with a couple strings of Christmas lights and I have a neon sign and it worked.
This all started for me when I bought some Chocolate Hanukkah Gelt (chocolate coins) off the discount rack for children, I bought 10 bags. I wanted to make golden coins for children. I make golden pennies with the sodium hydroxide I use for making soap.
Sorry for so long, thanks man, your genius rubs off on people and for one I am really enjoying my life because of people like you.
looks like 2.2 Ah / cell, at $1.60 and 3.7V that's only $197 / kWh, pretty good for over a year ago. However these are generic and just look on Ebay, there are $1 shipped '9.8 Ah' cells that reviews put at 500mAh or .5Ah which makes it low quality and a lot more expensive.
Plus you really want individual cells for balance charging and longevity.
The latest I know is that GM was getting quality cells from LG for 145 / kWh wholesale, that's more realistic, the best li-ion price I've heard of, and cell-only will always be cheaper, esp. in bulk. In short I don't see these cells being decent quality or close to advertised. They really need to be tested regardless of label anyways, like on a lipo / RC charger that can measure capacity. There seem to be a lot of counterfeit cells around, even an old, even new, genuine cell could be bad.
These appear to be LG DS3 cells (very common in laptop batteries). So these are definitely good ones, but they're low amp discharge batteries. So vaporizer mods, for instance, won't really work with these cells, but they could be good for lots of other things.
You might still not trust the label if it's from a generic pack (what I was referring to re generic)... and rest assured you are almost guaranteed to be getting a counterfeit cell on EBay if it's less than $4, and I'd highly question at any price.... if the packs were somehow direct from HP, toshiba, etc. I would of course definitely trust the cell labels... any 'OEM' online is highly suspect.
There really needs to be a good consumer source to genuine cells at a small markup, but that may not happen for years if not decade(s). $2 / cell comes out to about a 33% markup on that ~$145 / kWh LG price. Think if all power tools, lawn tools, and about every cordless thing of moderate size just had a simple 18650 compartment with BCM for unprotected cells. There are some packs made for scooters like this, just load with cells and close up. Even car packs could be made solderless... it'd take less time putting all the cells in than laying down a penny floor in a bathroom.
I was just saying these in the video were more than likely authentic. HP buys direct from LG I would bet so they won't be counterfeit cells. However, I have run across counterfeit LG, Sony and Samsung batteries (last time were fake HG2 cells) that I bought for a vaporizer mod. Needless to say I wasn't happy to get 10amp cells when I bought 20amp. LOL
could i use one of these batteries for a mod?
I wonder the same thing and if it's safe to do so..
I've heard of some doing this, but I'm not sure that it's safe..
i tried this and it actually worked and i haven't had any problems with it yet

I don't except anecdotal evidence.. Just cause it worked for you doesn't mean it will work for me or the next person.. And it's irresponsible to the vape community to spread this kind of practice.. It's truly not safe and it's has the potential for horrible things to happen..
depends on if your battery uses 18650 batteries and your mod uses 18650 batteries
