I've done about 400 packs of these, and had about a 97-98% success rate with cells being good. There's no right or wrong way to get them out as long as you get them out, haha! Love your videos, thanks for all of your instruction.
To scrape the black glue better. Use the plastic divider that was in between the batteries as a scraper. Since its plastic you can just go hard on it so I cleans better and doesnt leave black on the shrink
Instead of banging on them with a scraper and hammer, try cutting through the stickers on both sides with an exacto or similar blade. Then you can hold the battery in a vise and just push it open with no problem. I did a video on this. The ones I have opened have contained mostly LG cells and they are the most difficult to get the cells out due to the amount of adhesive they use. The Sony and Molicells were the easiest to get the cells out.
I am actually in the works of making a video about opening these modules right now :). I went a radically different route from Battery Hookup and you guys. I constructed a jig using wood, vice and a scraper. Also some advice, those scrapers have 2 sizes and you used the smaller size, using the larger ones lets you use less strike points.
I layed the packs on the flat of my vise and gave a light whack, to each side, with my Ax. Took less than an hour to harvest the last order I got from you. I got all of the same batteries that you did(only one pack had the red ones). Out of 68 of them I didn't get a single bad cell!
Take Care Jehu and keep the videos coming, John
PS, How about a video about a good size battery bank (like 80p x 4s) being charged by the alternator in a automobile. I am building a unit for my Suburban that I plan to keep charged to about 14.5 volts. I want to be able to charge it with a 300 watt solar panel (if needed when camping) and use 110 from my 3000 watt inverter. Thanks!
Get the Trim and Molding tool set from HarborFreight, use the big tool from the set to wedge the batteries out. The tool is plastic and won't conduct. Also use the same tool to scrape the glue off without tearing the stock shrink tube. I've done 1,200 of them and only had to re-sleeve about 30 maybe 40.
I'm really interested in knowing how many cells were good and how many were bad... Why didn't you share that info?
I purchased a pallet of 10,000 cells for a powerwall I am building. I am considering any cell under 2000 mah as failed.
I have a reject rate of about 5%. Now, that said, the majority of the "lime green" and "red" cells are not worth the effort of dealing with since they often don']t make my 2000 cut off. They are not necessarily bad, but usually, only have 1500-2000 in my testing (so I've just put them off to the side). Even with that, I'm running about 95% keepers.
Note:: if you are going to disassemble that many batteries in the same fashion, use ear protection. It might sound silly but you're experiencing 100s of repetitions of over 100db less than 2ft from your ears.
This is about the dumbest thing I've read on the internet this week... Seriously bro, sorry I'm not sorry
@@andyconda9456 guess he is afraid of thunder storms , world record thunder storm "on record" 700+ decibel .
Lol he forgot to mention that you can be around 120 dB for 2 minutes without permanent damage. That is 2 minutes of that loud sound SUSTAINED. As in, hitting the hammer on metal EVERY second for 2 minutes continuous. Pretty sure it took him 2-3 minutes every 1 second x 3 impacts. It's not possible to cause permanent hearing loss unless it is sustained or over a a higher dB which could cause sudden hearing loss, but a hammer on metal is not high enough to cause instant loss, but can cause sustained, if, as I said, you keep hammering over and over and over for several minutes without taking a break.
Protecting your hearing isn't dumb. You only get two ears for your life
Soft times soft men. Example:^^^
I grabbed a box of there as soon as they popped back on. Asked Batteryhookup for 50 packs and they gave me 52. Happy they did because so far I found one 0v pack. Last bunch I had 6 bad and only 10 cells coming out from 1500 to 1800. Now I’m working on the next box! Keep it up Jehu!
12 hours later “BAM”
this comment was made 12h ago
hahahaha yes! I scrolled to write this, "BAM"
🤣 🤣 🤣 🤣 🤣 🤣
You turned into Rain Man at 5:30 '97X BAM the future of rock and roll'... '97X BAM the future of rock and roll'...'97X BAM the future of rock and roll'
instead of cutting the glue of, you could use a hairdryer on medium heat when you take the batteries out of their shells, saves you from having to use a prying tool and a glue cleanup, BAM...just my two cents...
Thanks I’ll try that
Let IPA soak in for a minute and you can wipe it off
Good idea. Also, instead of an xacto knife, I use a wooden popsicle stick to scrape off the hard glue. Usually just flakes right off.
Lithium batteries degrade with heat...
No i think these are welded using ultra sonic welding machine. It is very common practice to to ultra sonic weld mobile/laptop chargers, laptop batteries etc. A very fast, superb finish and low cost way it is
I just placed my second order for a bunch of these. Good thing I ordered the last batch last night.
We appreciate the knowledge you share!
This will come in handy,I just ordered a bunch of the modem batteries thru your link,ty for the discount aswell.i also ordered 10 of them 20sanyo modem packs that are 17cent a pc cells.idk what I'm gonna do with 300 cells but I'm sure with your Vids I'll figure something out.God bless Jehu
To bad the shipping to germany is more expensive than the cells themself around 170$ :/
plus import taxes (i bought a few from italy, ended up costing 2.5x more when you add up shipping and taxes... )
Anyone knows local a reliable seller in the EU for used cells?
I don’t think we will have any luck in Europe. The regulation are forcing manufacturers to take everything back and be responsible for the waste stage. So used ones are almost only private people selling them second hand and thus trying to recover as much as possible. But most people would just get them to a recycling spot to get rid of it, or bring it back to the shop. I have heard from someone that did recycle old ebike batteries and rebuild them with the cells with good enough capacity. But with the new regulation, he has to stop since he doesn’t have the required licenses to recycle batteries... And since most batteries sold new here have te adhere to regulation and testing procedures, I think it will be the cheapest to just order the lithium cells on AliExpress. Or you have to be extremely lucky to find someone that is about to throw out a pc or something that is willing to just give away its battery
ArthursHD Hit up Grooter (grooter.nl).
I bought 300x 18650 back in mid ’19 but they dont sell them on ebay anymore. You may try your luck if you email them at 18650@grooter.nl
Same for France 😂😞
Never pry against a cell with anything. If you dent a cell never use it. I bent one once just a little on the bottom edge and 5 minutes later it was about to explode.
Dang it!!! this where I have been getting 18650s for the last 8 years and now you have let my secret out. STOPPPPPPPPPPPP
Wow. All brand new. That's amazing.
I'd be interested in how to add protection to these cells (individually), but in a professional way, that uses a very thin strap and thin insulation, to minimise the increase in diameter. I got burnt recently when I bought some cheap protected cells on eBay - they don't fit my devices.
After trying different ways of opening these, I've found the easiest. Get a 2 pack of groove joint pliers. Open them nice and wide to get a good grip. You should be able to crack them open effortlessly.
I imagine if you will do the Bam! While disassembling the other batteries
You know what He won't do the Bam with those batteries, he loves them so much he never gave me one 18650 cell!! Lolz men he is the one who inspired me to get into batteries n EV now as a career!! Thanks Jehu God bless you!!
Why not just find the mating connector and just leave them?
I wish I could find cells this price in Australia, really struggling to find anything that isn’t extortionate prices
LG then samsung rate best POWER cant find chit in oz mostly flat tops cheaper au $13 ? usa $3.50
Too bad the shipping to Europe is 10 times the cost of the batteries...
Especially right now
Yeah I had another package delivered with FEDex it was much cheaper but I needed more batteries for my pack, it a very big cost hehe.
You could check out nkon.nl
quesion: if you are making a 13s 48v pack out of these, can you use the different types of batteries in the same pack?
Jehu awesome video.. hey they throw these away at my job... so I picked up well over 50 of these .. I made a 36v battery for my kids electric ATV .. I'm not sure with work hour amp capacity these are .. I would like to know if they can be used in RC applications..
Why don't use a heat gun on low heat to separate the glue from the battery I mean that's what I would have done but you know watching how much heat I actually use
that is some premium recycling right there.
I found that the paint scraper blade works better removing the globs of glue than an exacto knife in the 8 pack modem batteries I am processing.
You are watching a Joe Rogan podcast as you work the batteries, and I’m watching you to learn about the batteries. Circle of knowledge. Lol thank you for sharing.
I've found that I can usually get it apart just splitting the side without the connecter, then prying it apart with my hands, s little bit faster
Hey you can sell the battery charging balancer etc, through online
08:37 Watching Powerful JRE while doing some battery work. Nice
I've found that you can use the plastic separator as a scraper to remove the glue without harming the heat shrink.
Brilliant!! Thank you.
They bend too easy...
How many of those do you need for a 12 volt or a 24 volt battery
This is not the way to go for EU market. :(
If you know a good seller here, please give a link
TecSanento op marktplaats staan ze voor €1/cell met 90%+ capacity
Wot u mean a good seller there's no such thing ....don't you mean cheap seller then you be buying double or triple cus they shit.... That's why they getting rid of em
Is jag35 safe??? Did you get your cells?
When I get my mini windmill back up and running, I plan buying something like this for my 1-2kwh pack.
Batteries in modems? Wth? I've been using Internet over 20 years and never had a modem with any battery
Bam! There you go! 😁
I have seen shrink wrap for them on Ebay. I bought some clear for the 38120's just for extra safety and cause they were soooo cheap.
BMS from those battery packs will still works with some few modifications 😊. Use resistors (1k).
what about using a ruler as opposed to the pcp?
Flattened scrapper works with a handle
Please somebody let me know how many of those cells do you need for a 12 volt or 24 volt battery please
Hello sir. You should never try to peal down the sripp from the negative lead. They are spot welded and when you taking off, you can create electrolyte leakage. It is best to cut it as short as possible. Best regards !!!
Thanks for your video! So many new ideas! Greetings from Germany!
Thanks for the video ✌️
Allready sold out 😞
Stay safe
No.... unless 50k just sold in an hour which I guess is posible but don’t think so
@@jehugarcia ur right, I double checked...1170 still there.
Thanks for the fast reaction
Good price, but shipping to France is too expensive though 🙏😬😇
It seems like the amount of time required to separate each cell would make the cost per cell higher than just the price. If you don't value your time then these might be the cheapest cells. It seems like it would be cheaper to just buy a factory made battery.
Correct, if you can afford new cells, may I suggest www.evwest.com/catalog/product_info.php?products_id=483&osCsid=i9qccji06mcqm82enffutrhtd6
Hah! Jokes on you, my time is worthless!!!
can these be used in a ebike? Or do they not put out enough amps?
These come out to be nmc batteries?
Were he used the PCB to pry, I used a Paint scraper, metal or plastic.
Tried to buy 50 units. Shipping was $160 on a $90 order. I guess it's worth while if you want to order 1000s, but I'm not sure I trust the website to place that large an order straight up.
Exactly, my shipping came out $100 for 100 quantity.
Would it be possible to connect these modem packs in series or parallel and build a bigger battery pack instead of separating them?
We haven’t figured out how to yet
BAM
What are those ? And if its new why crack open them ?
Did this really sell out in five hours??
I thought you couldn’t use different 18650 cells in the same pack?
A bit of isopropyl alcohol would probably be easier than wedging the pack apart with a PCB
nice playing some joe rogan and tim pool in the background
Wouldn't a little heat release the glue?
I’ll try that next batch
Is there not a way to hook paks together to make a power wall?
Percy Brown those connectors cost so much, we don’t have the modem, you’d lose in the long run. You could rig up something but I feel it’d be unreliable. Better off with welded or spring contacts.
Lol is that the Joe Rogan & Tim Pool interview on your laptop at the end there?
Is the LiitoKala-Lii500 still your go to for 18650's?
Excluding that 16 battery charger u just reviewed that comes with the app on kickstarter. That looks pretty cool tho.
Nice but plz use protection when you open the case
Hey! I was wondering if you could test out a 2700 cell.
I want to know where the batteries are that I bought I got an email from you today stating that they were here but when I go look nothing there. So I rechecked the email and then followed the UPS tracking link and lo and behold they wound up in SAN MARCOS, CA, US instead of Broken Arrow, OK, US. So what gives?
I always save the board’s. Some of them have good plating around the terminals. You would be amazed at the refining of these if you get enough of them. I love to do it. Anyways Jehu brother we love you in Ohio.
I would re-wrap them. 😄
Nice!
Thank you Jehu :)
I don't know lot about batteries but I bought them and they are low amperaje one . Right?
8:12 do you recycle the nickel strips or do you just but them in the bin... i mean the amount of cells you are tearing apart and over the years... a lot of money wasted ??? Hermano to no eres de Lima???
How do I get this in Europe?
Sup jehu you share very knowledgeable information 👍👍, learned alot by watching, I'm kinda stuck on how could I wire 2 24v 18650 battery pack in parallel if I need some type of balancing. Both my packs have bms
Music in video: Electric mantis - Daybreak
Love the high tech tools! LOL!
Don't use the red Sanyo cells, they are known very old cells that are known to heat up alot and possibly catch fire during charging. The samsung and lg cells are fine but know that the modem manufactures those are the cheapest ones that they make, to prevent the the modems from using cheap chinese cells instead.
Do i have any way to contact you. Need some help in battery stuff.
You know you can take your wire clippers an cut on both sides of the plug in an pop the seam.hate to see someone who smacks that blade into a battery might be a little dangerous
Jehu is it possible to build your own electric go cart 4- wheeler etc?
Literally used these for my power wall. Only used the LG and Samsung's. Dumped the Sony's and the Sanyo. They did not test well
Used a plastic auto trim tool to break the glue blobs.
Hey man, what´s wrong with those cells you discarded? did you test them all before putting the pack together?
@@andretodopoderoso7 only 10% were Sony or Sanyo and they were testing at about 75% capacity while the LG and Samsung all tested near 100% do I decided to not use the Sanyo and Sony. I'm sure there are some good Sanyo and Sony but after a few bad tests I just stopped using them. Luckily these packs are mostly LG
Stevenc22 where can I find these?
@@devinallen9877 usually battery hookup for these cells.
Wish i could buy. i feel stock get cells
1:50 does your Waking not Damage the Batterys??? Hammering a Battery is always a bad idea???
The scraper blade is puncturing the plastic, and there is an air void just below the surface where he is hitting. So the way Jehu did it is great.
Can i have 10 of those battery for my solar at the rice farm ( for light purpose only )
2$ on batteryhookup, very cool.
slowly heat the black plastic with heat gun to sofen glue
What should I be looking for to get these sort of deals in Europe? What sort of companies would sell in bulk like this? I live in Ireland.
You mean used? To much of a liability issue here in Europe.. You could check out the scrap yard or look at nkon.nl for a good deal
Sir I'm from Philippines, your my idol i watch almost all of your videos, i want to buy this BPB044S modem packs or your lithium battery 18650 for my diy project because you inspiring me, sorry for my English I'm not good in English, thank you sir
What are modem batteries?
What is some uses for those?
At what capacity percentage -wise do you bin the cells, compared to their as new rating ?
I'm not sure if it's a capacity question. Personally, I'd dump any cell which I felt had significantly less capacity than the majority of cells which I wanted to combine it with.
I'd also dump any cell which showed any signs of heating up during normal charging (normal charging for a Li-Ion cell is charging at half its C rating, so if you have a 2500mAh cell, the initial charging current should be limited to 1250mA).
In theory, a Li-Ion cell can be fast-charged at its C rating (2500mA for a 2500mAh rated cell) but in practice, the cells wear out more slowly if charged at half the C rating.
@@melkiorwiseman5234 thanks for that I noticed that the majority of SANYO cells seem to heat up and that is without even “pushing” their charge rate
@@pollywollydo My first guess would be that those cells are cheap "knock-off" copies from China and not Sanyo brand at all. Any Li-Ion cell which heats up during charging is either being charged too fast or is damaged. Causes of charging too fast are limited to using the wrong type of charger for the cell, or the cell is fake and does not have anywhere close to the capacity it says and so it's being charged too fast, which has the same effect as using the wrong type of charger.
And by the way, the largest capacity 18650 cell is around 3700mAh, and even those are rare. The largest commonly used seems to be around 3200mAh. Any cell claiming a capacity over 3500 should be regarded with suspicion and anything over 3700 is almost certainly a fake. They usually have a 1000mAh battery (or smaller) inside the case, with the rest padded with sand or something similar.
@@melkiorwiseman5234 as far as I can remember they all ( I think) came from mostly reputable computer packs which I stripped myself rather than bought unseen a large % Sanyo I binned whilst the Sony LG and green Panasonics were fine non were charged too hard . I have had some descent stuff occasionally from yik- lik and Moli thanks for the info- always useful 👍
Guess what I'm doing while watching this video I'm stripping down laptop backs
Bam!! 😃
The cost of shipping to Europe is more expensive than the product itself. For my case, from US to Romania is around 100 euros with DHL. So..... is not worth it. If you can make a deal with a European dealer i will buy it
There are no similar sources for large quantities of used lithium cells in Europa.. But you could check out some cheap new cells at nkon.nl for example
hey.how are you?
Please get a Europe warehouse, so we can buy a bunch of them and don't need to pay import taxes and expensive shipping. Thank you!
You would need to pay the taxes anyway... Through the price he asks then. Welcome to Europe my friend ;)
Peanut butter and "Bammmm".

Hola garcias tienes 18650 2900ma
I bought 100 packs of this with average of 2100 mah
