- 18650 Mountain - Part Xi - The Process
The SUMMIT is in SIGHT. 5000 cells later, countless days and weeks have gone and with every small snip of the cutter each cell has been freed.
In this video, I want to share with you what I have learnt freeing the 18650s and how I setup my workflow to make it more of an efficient system to get through this mammoth workload.

Buddy that was an awesome vid, loved the mention !!!! Got your "18650 Awesomist Battery Charging Thingy" today and love it. I'll put it to good use before we find it's new home :) Pete
Pete, you doing grat job too
A good way to cut open the shells is to use an oscillating tool. You cut a slot in the work table for the oscillating blade, mount the oscillating tool under the table with the blade sticking through the slot in the table top, raise and lower the oscillating tool to get the depth of cut you need. Then just run the shell over the oscillating blade and cut the case open. There are all kinds of blades to use, coures cut, fine cut, round and flat blades, pick the one you like. Please use push block made of wood to move the shells through. Watch fingers!
I've shelled some batteries using pincers. One blade goes into the crack in the shell, the other wherever it'll grip, then twist. Works quite well.
I use side cutters similarly for removing the nickel strips but my advice is to start at the negative end. Doing the first strip is the trickiest as things are tight so if you nick the battery covering your not going to short it as would happen with the positive end. Once the negative end is removed you can then part the batteries and the nickel strip on the other end peels off so much easier.
Hey colin, thats the idea, safety first but sometimes I like to live dangerously and attack them from the centre LOL joking! no one try this its very dangerous!!!
Epic Tetris 18650 work!
i recomend you invest in a set of good quality long pincers, sharpen the cutter jaws to flush cut. its the only tool i use to split the cases, cut the bms wires, cut the nickle strips, then can grip the strip tails & roll peel back the remaining strips off the cell ends. no other tools needed
"There will be blood"... so true. I took a break for my 18650 processing because I lanced open my finder something fierce. Had to really asses how much I'd be willing to pay to keep all my appendages. But the call of repurposing something destined to be rubbish calls like a siren.
Oh man! be careful. The laser machine has been a god-send. i opened 130 packs manually last year and it took 4 days to do this and it was so exhausting on the hands, wrists and arms by the end. Even had a few that burned me! Not sure how others have dealt with this with larger quantities. Hence, initially the mountain was such a daunting prospect until I had the idea to laser cut them open.
Fantastic video.
I figure I would use a vice, put multiple packs in the jaws, then bust out an oscillating tool and run the blade enough on one edge so I could then just rip it apart by hand.
But I haven't tried it.
If you work in an environment like the garage or workshop, you can use an angle grinder. Likewise, you start from the power contacts.
STOP MOTION IS EPIC!!!!! IM BACK ILL BRING SOME FRIENDS :]
LOL thanks mate your awesome
Impressed you did most of the work without gloves. I found I cut my fingers to shreds on the metal burrs. For the packs; I tend to use a vice and twist them with some large jaw pliers to break them open. It's messy, but seems to work for me.
The laser cutter was a god send. At times I did burn the batteries sleeves but TBH this was not such a big issue as they can be re-sleeved. But I found brealing the work load into its smaller processes and doing these in bulk really helped keep organised, tidy and injury free.
I use to take apart packs like that. Now I take a hammer a few taps down the seem is splits open. 5 seconds you have the pack open. Obviously don't hit it like a nail. But low/medium force will split the case and not hurt the batteries. If you really wack it you can dent a battery. But its much quicker. And I just pull the batteries and wires apart. Then take pliers and remove the battery weld tabs. Lots of failed battery packs have a couple good batteries still and sometimes the circuit board failed and all the cells are like new or new. I've found most tool packs the board fails. And people leave discharfed packs to long. Tool packs have a MOSFET to kill the pack if the voltage drops to low. Always recharge lithium tool packs after use don't let them sit for for months on end discharged. Below 2.5volts the MOSFET opens to drain the pack to 0 to kill the pack for safety
I have managed to get down to a very short amount of time per battery... I take a set of pliers and grab an edge and twist. The battery splits open no problem.
I saw the video yesterday that said" NERDVille is dead" and my immediate thought was that you'd had a catastrophic 18650 thermal runaway situation! I'm glad that's not the case, I've loved all of your videos so far and am keeping a close eye on your channel for new ones!
I use 18650's in all of my vaping equipment, and just wanted to share a valuable resource for information on Lithium cells, this guy is working with them everyday and testing and graphing different brands, His name is u/Mooch315 on Reddit and just "Mooch" on a few other sites, he's been an absolute godsend for us vapers.
In my opinion, I wouldn't have a problem with seeing 2 or 3 ads per video, as long as it helps you out, I've loved the series so far and am now hooked!
awe mate thanks means a lot to me. Honestly its not for the money but I hate Google making (more) money off of my hardwork.
I hope to do more stuff on the channel than 18650s but they will one way or the other be about 18650s
I like the animation in the begining .. 👍👍
Hello
first I have to tell you that your old nerdville is awesome so 👍...
like'it
your videos are something special...
Your amazing thanks so much for the support
I have found that if you can get a good firm grip on both ends of the battery and can twist or flex it at all, the case generally seperates at one of the seams and opening it the rest of the way is easy. No tools are needed and little chance of accidentally shorting across the terminals of the cells or the power board.
I use a pair of good quality secatears so far opened about 400 packs with the one pair, sometimes augmented with a pair of vice grips
I saw this on another channel once. Good idea that!
We like you keep the good work man
Holy crap! Dude, so much work. I'll happily go back through all your videos and re-like them. Looking forward to seeing what you use them for. I need to grab several hundred 18650's for a power source in the months ahead.
Oh man! thanks Andrew. Well My mountain was daunting at first glance and there was a ton of procastinating from me to do this, mainly, when I did my initial 800 cells a year before it was so so hard. BUT with the laser cutter, honestly it was so much easier.
GOD BLESS MY LASER MACHINE!!!
Anyone reading this comment, MUST go and follow Andrew's Channel he has just started an 'Electric Boat Project' and I truly cannot wait to see the conclusion. AWESOME
NERDVille Thank you so much Nerdville.I truly hope to get a laser machine at some point in the next year. But I'm spending serious money on my current project. Where did you get yours? It's pretty powerful to cut through those cases as well as you have. Nicely done!
I appreciate your constant cheering for my channel too, my friend. I'll make sure to give you a shout out and change my link to you in my old video, where I tell people to check you out.
Sorry for the headache, but at least you're catching it early on. Keep on keeping on.
Hey Andrew, you rmost welcome and I wish you every success on the great channel you have... you deserve it mate.
Here is a link from the UK eBay but i'm sure you can get a better deal from US eBay
www.ebay.co.uk/itm/60W-Laser-Tube-CO2-USB-LASER-ENGRAVING-CUTTING-MACHINE-with-Red-dot-position-/222024445071?hash=item33b1b02c8f:g:h-EAAOSwe7BWwSKv
Excellent video
Great site. Already producing advertisement income I hope.
I use a sharp pair of wire cutters and start seams. Once I get a gap I move the pack to the edge of the workbench, overhanging as much as possible and still maintaining leverage, and insert either a thin standard screwdriver or a chisel into the gap and press down on the lower section. This tends to split the lower case along the seams. From there I follow a similar method.
You mentioned nipping off the weld debris. In addition I use round end of electric scissors to smooth those little barbs out so I can handle the cells without slicing tender finger pads.
Whatever gets you there fastest. I also use much thicker gloves and therefore fewer BandAids.
Love the new site.
Great work thanks a lot for sharing
thank you its was my pleasure
I've found a dremel cutter disc down the weld to be very effective.
Also, pop in freezer for 5 mins.... hit edge ways on against concrete garage floor with hammer.... dont let the batteries cool off too much... not sure how it affects the lithium/cobalt mix in most of those batteries but I wouldnt chance leaving them in there for hours! Works well though on some of the tougher cases.
Liked all the videos you reposted. Hope the new channel grows fast. Keep up the good work. Thanks for the videos
Awesome videos!
You should never go in from the power connector face. Attacking it from the other side is far safer. I use a pair of woodwork pincers on the rear lip, which breaks the case easily on the right angled turn, working along that edge leaves you with a full length opening. You can then often prise the case apart, though sometimes you have to also break the two sides on better quality brands. This leaves the BMS safely out of the way, and the end terminals can be disconnected while the cells are still sat in the other half of the case.
OMG! just saw your stop motion intro, it is so fantastic that I first need to pause and comment on that before watching the rest.
I had to laugh so hard that I woke up my 3 week old baby. :))))))
All resubscribed and every video liked. What a mission for you my friend! Took it like a man though🙏
your awesome thanks
To increase those levels of peril, I found using a sharp ~19mm wood chizel works quite well. the sharp end does a good job getting into those seams and the extra width helps crack the case open as you twist.
I sharpen the medium end of this tool like a chisel and use the wonderful leverage it offers. www.amazon.com/Red-Devil-4251-Painters-6-In-1-Tool/dp/B00002N6IT/ref=sr_1_1?ie=UTF8&qid=1478308622&sr=8-1&keywords=painter+tool
Good work
Great video. Your production value is outstanding. Just finished processing my first batch of laptop batteries.Ended up selling the processed batteries on Ebay since i dont need a powerwall. Did it more for the experience than anything else.
I like to snip the ends off the battery case with wire cutters then split the battery on the weld seems. Works pretty well. Have multiple different brands of chargers but in the end ran everything though multiple Lii-500 since they can be charged discharged and charged again in a single device. Interested to see how you processed the batteries since that many batteries required awful lot of testers to be efficient.
Thanks for the shout out NV. I can relate to your desire for more batteries. Been feeling the same urge here too.
On opening batteries - I wasn't keen on going in via the power connector for fear that I might short the cells with my screwdriver. Not sure if that's an unfounded concern or not.
And an extra throught on 18650 heat shrink sleeve - go for the light weight PVC stuff, not the thick black insulating heat shrink. You don't want to hold heat in the battery too much. And the thick heat shrink won't fit into standard 18650 battery holder clips.
Another great video. Cheers, Paul
Yes - I prefer to attack from the sides or ends away from the power connector
It depends on the battery for me. I have very good and consistent experience with Lenovo batteries using a painter tool with the medium side sharpened by my dremel. A HUGE amount of leverage can be utilized by that tool. It doesn't work so well with the Dell ones though.www.amazon.com/Red-Devil-4251-Painters-6-In-1-Tool/dp/B00002N6IT/ref=sr_1_1?ie=UTF8&qid=1478308622&sr=8-1&keywords=painter+tool
i liked all of your vids !you deserve it. keep up the good work good luck with this new channel
Heelo again ! count me in !
Keep on trucking ! (from France)
all right mate, went through all your videos and liked them.
I'm subscribed to hundreds of channels bit I DO THINK that you have a voice (in the maker universe) that totally deserves to be deployed. Thanks for putting the effort into all this, looking forward to what comes next.
Much support and respect !
Marc
I took a laptop battery apart where the + and - were in the same tape like trace, i had to use some scissors to disconnect them because nothing else worked, the battery shorted out and the scissors died. The cells were not even 18650, they were a crappy strange panasonic design which are slighly taller than 18650s and slimmer, they didnt even warm up when shorted too so those went straight to the recycling.
Resubscribed and reliked. Keep up the good work.
Thanks again, sorry for the inconvenience and looking to moving forward
I was really sad at first when I saw Nerdville is DEAD in my feed but luckly you just moved. I only prossed about 250 cell out off 33 Laptop packs and this sens of achiviement was overwhelming. Now if tested about one thiered of the cell for capazitiy and with 2 Dischargers its pretty quick. Just put two in when I leave for university and test more when I'm back.
Hey way to go my friend. What is your plan with your haul of 18650s?
NERDVille I will use them of the speakers I build and also for a kind Powerbox (build in an ammuintionbox), this won't be anything like a powerwall it's more like a prove of concept. As a University student I life in a apartment so I can't put Solar on the roof. If I finde a shop that could build me a Cargobike to me drawings it would also 18650 that. Some of the 18650s also find there way into smaller projects. Currently I'm working on a Automatic charger but to get that working I need my 3D Printer which is currently preordered.
Hello. Nice vid. Question :how did you get so much batteries?
the time lapseis amazing! do you do all the editing yourself?
Credit goes to my kids. My daughter provided the voiceovers with the help of her brothers. Sometimes I leave them in my Nerd-Cave with the cameras and they always make something that makes me laugh. This one I had to share.
you absolute superstar!!! thanks mate it means a lot! its a big step of the abyss for me wasn't sure what was going to happen but this support is just overwhelming thanks again. i'll suggest to Pete to send the Awesomist Charger Board to you!
NERDVille i don't have heaps of subs myself but hopefully it helps you a little bit thankyou for your content its the best
Running a dermal with a cut-off disc around the seam line is way easier...oh and it is not a monkey wrench (pipe wrench), they are channel lock pliers (battery pliers)...
Haha that tetris :)
Nikola Nikolov the one and only!
resubscribed and like all your videos. hope all this won't set you back to much
Thank you sorry for the inconvenience, really appreciate that
Amazing work. What is the reason for processing over 6000 cells? to make your own power wall?
still undecided but loved the challenge of recycling these and have the cells at hand once I decide. I want to do something spectacular but also something I have dreamed of. will update everyone once I get more information
I use nail pliers/cutters. Allot faster and safer.
Would you mind sharing a link to which laser cutter you have? I have been starting to look into them based on seeing it used in your videos, and I think I asked you about it before. Most of the cheaper Chinese ones I've seen are "engravers" but I really think the cutting capacity like your's has is key to it's usefulness (as you prove). Thanks for your help, I've subscribed to your new channel!
Hi Yes of course. mine is called a Red Sail Clone and if your in the UK this is the eBay listing and there are many like it. I bought mine 2nd hand of a guy who wanted to upscale and my laser has had its laser tube and PSU upgraded to run an 80W tube.
When the Pound Stirling was good, this could have been bought for less than £1000. Sadly everything is 20% more expensive

Ouch, I'm using Dollars, so even more expensive for me! Nice machine, but I think for me to have that kind of capability, sadly, it will be a while before I do... But thank you for sharing, at least I know the $ figure to have that kind of capability in your garage (and it's still within reach if I forego all the other stuff that is on my list...).
On another topic, the production quality of your videos are spot on.. as well as the information, most importantly.
You may find a cheaper one from your local eBay as these are typcally chinese made machines, best of all look for a second unit that has not been used much. You'll be surprised how cheap these can go for. Also checkout Russ at czcams.com/video/JfRpa9Y5Woc/video.html who has been intrumental in taking the time to break down these CHEAP machines and advice on what updates to make these a more safer machine to use. Drop him a msg let him know I sent you.
Awesome man, THANK YOU!! Much love.
I did post a short video few month ago showing an other way to open this particular battery pack : czcams.com/video/NRg62AMB590/video.html
As you can see, I do NOT touch (or even take the risk to do so) any internal part.
I push the tool angled toward the outside of the pack, and only one shot is needed to open it.
In my mind it is much safer, for your body ;-) but also for the pack itself.
Needless to say it is much faster.
I have 18650 lion 40 peces cell. I want to make battery pack of 24 v 15 a battery pack so Wich bms I have to buy
I want be doing any box's I can't find the cells where do u get yours
Where do you get so many laptop batteries from in the first place?
Would a vice not be good idea to save your hands?
Where the heck do ou have all the laptop batterys from?????
This 18650 are they good for vape mods
Yes I imagine so. current/density is very high so very good. My best cells do not show any signs of wear and on average lost 10% in capacitance.

Ah, the long intro. A waste of 40 seconds.
Hi Colin. I know... I know... and i'm sorry TBH i get more praises for thelong intro that complaints. Saying that one of the most successful TV shows in the world, its intro is 1m45s, which is Game of Thrones Ironically!.
I am planning a really short 10-15 second intro as I try and try and try to make short 5 min vids but I honestly struggle. Just a stickler for detail thats my problem. Bear with me i'll get there.LOL
NERDVille leave it its so dam cool
I love it, if you don't like it just skip to the 40 second mark?
I always try to skip intros on all videos...
NERDVille while I like the intro itself a
