When balancing the voltages of cells you are connecting in parallel, it is recommended to first connect a 100 ohm resistor between the cells. This limits the current and allows the voltages to equalise while maintaining a safe temperature.
Thanks mate, you’re a lifesaver. my first foray into recycling vape batteries, I made a 12 V lipo (3S3P) to power a fan and while charging, it went off like a smoke bomb and I wanted to make it safer before I attempted again
I connected 3.41v lipo with 3.89v lipo battery and I used resistor leads has Fuses they didn't blow up but it took about 10 minutes for them to get back down to 20°c and the cells when connected went up to about 35°c in that time so was I forgot I put two lipos with different voltage together I think I was lucky enough to tell the tale
heya @@meltedcheese1091 i'm looking to do similar as you did, 12v. what charging / bms boards did you settle on?
Thanks buddy. I have wondered that and only recently bothered learning circuit board diagnosis so I’ve seen them on BMS, but never with cheaper ones that don’t have internal balancing. Might be a good idea to use a resistor equal to the c rate of the batteries
you are such a good advocate of recycling those disposable vape batteries from them being thrown into waste
I have tested about 60 of these cells & the capacities vary considerably. Some of the worst have been 545 mAh while some of the best have been even up to 640 mAh! It is especially important when connecting them in series to match the capacities. If one becomes discharged before the others in a battery pack, the healthier cells will try to reverse charge the lower capacity cell. This must be avoided at all costs! Like everything with lithium cells, this is a serious fire risk.
Neat build. I did like those power banks from Poundland. I probably should have bought more of them at the time. Thanks 😀 👍
I bought quite a few as they were cheap batteries and work fine for my purposes 👍
This is good for the environment and also makes the rechargeable lithium batteries a second life in a new device!
I'm doing this right now aswell! Glad to see there are others 😊
I bought myself a metal 50 cal ammo box and I keep all my vape batteries in there. A biscuit tin is better than nothing, but I think it would still melt through if all of them were to light on fire. Stay safe everybody and make sure you're respecting these lithium cells. Don't store them with any combustible materials, don't pierce them with sharps, don't leave them in direct sunlight, and don't overheat them when soldering the tags. Don't overdischarge them too! If they fall much below 2.5 volts the internal chemistry can begin to change & they degrade. This can increase their internal resistance which leads to heating on charging & discharging, which becomes a fire hazard as they exceed their safe temperatures!
Interesting how you was saying about internal resistance because I tested one it had 65 ohms and other one had 35ohns so we need to remember to use same cells with same condition same voltage and same mahs and same internal resistance because if we don't we could have problems with them thank you for letting other people know ❤
No rhey womt burn through a bicky tin@@billyjoegilmour95
Hey that works great! Well done Grandad😁Might have a go at doing that with all the discarded vapes I've picked up.
It made me smile that I used the circuit board that I had taken out of a power bank to make a power bank. Double bonus that using the clear PLA allows us to see the LEDs inside 😊
Also where did you het the blue charge meter from please. The charge doctor ?
I've been looking for a project, that I can use some of those damd vape batteries on. Thanks for the insperation.
Yes, I have collected more than I am ever likely to use, although I do use quite a few on my RC cars and boats. Because they come in various shapes and sizes, they are handy to build batteries to suit my requirements.
This was a very informative video really enjoyed watching this lots of good information thanks Grandad 👍
Personally, I would worry about people copying this if they have no knowledge of the dangers of lipo batteries. The lipos are far more likely to catch fire than lithium ions 😁🔥
@@GrandadsOtherChannel you gave a warning try not to worry 👍
You should really advise disposing the lipo’s that are under 2.5V or try to charge each cell individually to the same voltage then connect them together in parallel.
Have you tested the little power bank modules?
Tested them in what way? I use them and they work fine.
@@GrandadsOtherChannel do they have over/under voltage/current protection what quiescent current etc

Thanks, will do.
Nice to see you are helping to keep junk off the Streets. There needs to be more of an incentive to recycle these devices.
My point of view is that vapes contribute an insignificant amount to the general litter in our streets and there are already laws against littering, so there should be no reason to "reward" people for doing what they should be doing already. Check my video description for the related playlists on this subject.
I am trying to make something very similar to this, it’s going to be made either with vape batteries or 18650 cells from old laptop batteries, and hopefully I can use a small solar panel I have as an alternative charging method.
bigclivedotcom does a lot of that sort of thing, if you haven't seen his channel, it is well worth a visit. www.youtube.com/@bigclivedotcom/videos or www.youtube.com/@bigclivedotcom/search?query=solar
I'm trying to do something just like this. Do you have a recommendation about what charging module to get from ebay? I would like to charge at 5V 2A if possible. I've seen some QC charging modules too, but not sure if I should trust them.
details in the video description.
I have about 200 of these, using them for all sorts of projects
Yes, I have stopped collecting them as I have far more than I will ever use 👍
@@GrandadsOtherChannel ditto
What do you think is the maximum number of these cells you could use with this power Ank circuit board and how would you wire them?
Second part first. You would wire them in parallel. That board only supplies voltage for a single cell, so in parallel it only sees a single cell. First part. You would have to read the spec of the board to find out what current it can supply and do some maths. Generally, those boards are rated at 1 amp, although you can probably change that by replacing the reference resistor. Personally I think that 3 of those small Vape batteries is about right. I wouldn't push it any further with that module. Alternatively you could try what you like and just ensure you test it in as fireproof environment.
I have few modules laying around..I will try this at some point..
Be aware that lipos are far more likely to catch fire 🔥 so you do this at your own risk 👍
@@GrandadsOtherChannel sure....I have lithium ion batteries...
A friend recently gave me about 30 that are suppose to have 650mah batteries in them. I know about the fire risk of these things so I've placed them inside a .50cal ammo can and locked the lid. I figure if one were to get upset lol the metal ammo container would keep the fire confined. Possibly not even allow a fire as the Ammo Cans are almost perfectly waterproof sealed when closed so very little oxygen would be able to get inside.
congrats u just made a rather big pipe bomb... lipo does not need oxygen to burn thats whats makes them impossible to put out. u need a container that can vent the gases without igniting anything else.. and contain the fire until it burns itself out.
i also have a big ole box full of this stuff. i use em for everything.
Just remember they can catch fire, so safest to take care of that big ole box 😁👍💥
Interesting. I've collected a load of old vapes. I wil probably do the same sort of thing unless I find another use for them.
I use them for my RC cars 👍
Hi what are the modules called that you use in this video. Thanks

Thank you so much 😀
Are you using a li-ion charger to charge lipo batteries? I thought you were meant to change one of the surface mount resistors?
The surface mount resistor sets the maximum current draw. The circuit board I am re-using in this setup is not ideal, but close enough to work fine. It is probably slightly under the maximum current draw for the 3 cells in parallel. As it was from a li-ion cell powerbank, it will also be slightly under the ideal voltage for a lipo, so in summary it will be slightly under current and under voltage, which I would prefer to being over current and over voltage.
@@GrandadsOtherChannel you can make it out put maximum of 2 Amps so if they had lots of cells the same it be easier to leave them all changed together it's safer than doing few at time 2A if you had 10 you could change them all up with 200mah so if you was to do that they could last more recharge cycles the hotter the battery 🔋 that's big problem anything getting over 40°c should be not used has it's got problem with resistance because it loses more power = bad
I read that the 18450 battery’s inside those disposable vapes arnt suppose to reach above 3.7v then being recharged up to 4.2 is apparently dangerous but iv collected a few of the batterys and charged then in the slowest safest possible and it seems to charge then all to 4.2v
So is it normal for these cheaply made cells to do that?
I guess you can read what you like. For information, these are not 18650 lithium-ion batteries. The 18650 refers to the dimensions. 18mm diameter, 65mm length, and the 0 at the end indicated it is a cylindrical battery, rather than a rectangular battery. the 0 would be replaced by the thickness with a rectangular battery. These are LiPo batteries, so that is technically a different voltage scale, but regardless of that, you would do well to research what those voltage scales are. I would suggest a genuine battery manufacturer site, rather than a TH-cam video. 3.7 volts is just the nominal value quoted, in the same way that 1.5 volts are quoted for AA batteries, even though they start higher and drop lower. When you charge a LiPo battery, 4.2 volts is the fully charged state and 3.2 is generally quoted as the minimum discharge charge. Li-Ion batteries used to be quoted at 3.6 volts nominal voltage, but marketing forces have allowed that to change to 3.7 volts.
Oops, just noticed I was talking about 18650s and you were talking about 18450s. In fact, the ones I used in this power bank are 13400, so that is 13mm in diameter, 40mm in length. All the rest of the information is correct. There are a whole range of sizes used in vapes. I have quite a collection.
Nice one Graham. I think it is brilliant that you are using these disposable vape batteries for other purposes. This little power bank is great. Easy to pop in your pocket and has plenty of capacity with the cells connected in parallel. Top job. 👌👍👍
My main concern is that Lipos are more likely to catch fire than Lithium ion batteries so I am not recommending this, just answering a comment. I made a couple of them and they do work fine.
Hej i have alot of vape batteries that i have found. I would like to make the project in your video. Do you have an ID number for the charger boards or a link where i can buy them please ?

@@GrandadsOtherChannel Thank you.
I’m an idiot. But having ideas.
How many batteries would you deem “safe” to hook together 3 max? 4-5-6 or is the number infinite? Also the 4000 watt bank put out the same capacity?? Ok but how long do each last on a Full charge side by side? These are all questions I’m probably gonna have to answer myself aren’t i
Quoting from somebody else's article. Generally, when charging LiPo batteries, you should charge them at 1 amp per amp-hour of capacity. so, for example, you charge a 1500mAh LiPo at 1.5 amps. (1000mAh → 1 Ah) (450mAh → .45 Ah). That charger module is probably rated at 1 amp and those LiPo batteries are probably 450 mAh, but my understanding is that you add the capacity if they are in parallel, so 3x450 = 1350mAh. That means they would be charged slightly under the optimum, but that is safer than overcharging them. Charging at a lower rate is not a problem, charging at a higher rate is a fire risk. Unfortunately all the manufacturers use different ways of describing their battery performance, so it is not easy to compare them unless you have one of each and a specific task you want them to perform.
Amazing video this is exactly what I had in mind. I already have some of those single 18650 battery power banks from poundland that I can take the charging module from and now I know it works I can do the same thing you have done here. I also have 3 old laptops with 18650 batteries that I intended to use for a power bank. Your video has prompted me to order a welding-free power bank case for me to put those 18650 batteries to good use. You can simply slot the batteries in the power bank and they are very cheap. Thank you for shower me this can work.
Good luck, I hope it all works out for you.
Hello, I’ve burned down my garage and my Lawyer said I should attempt to get in touch with you.

hi , i got plenty of same vape batteries , can you upload file for 3d printing that box ? many thanks

Power bank yes ive got 16 500mah and ill be using a tp4056 usb-c charging board for them i was going to wire them in parallel directly now whats this about resistors ?
If you look up the data sheet for the TP4056 you will find there is a reference resistor used to set the current output. By default, most of the TP4056 modules are shipped with a resistor setting them to 1 Amp.
I'm gonna try this with a working single cell battery board, And 4 900mah battery's they fit great and it would be more power 🔋
One way to find out 👍 Just take care, be prepared in case the worst should happen 🤔
@@GrandadsOtherChannel I understand outside and sand bucket nearby, My father will be assisting he knows way more. And this will all fit inside a altoids tin
It will be 3600 mah in total, I can't wait to test it out when completed
what i do with these street lithium guys is i bought some super cheap, ~3 buck under cabinet PID activated LED light strips. its a pain to charge them but since I rent i figure its the only way to have any lights without making permanent changes to the house. i just solder them in parallel with the somewhat not so generous included battery pack, im ignoring the built in BMS thing but whatever. with their power saving motion activation and a small external tumor, they went from needing to be charged every 3 weeks to every 3 months. what worked even better was my old leftover iphone 5 batteries. because theyre so thin they fit inside the original enclosure usually. i recorded a video showing how i made them but just havent had the time to edit it and upload it to my channel
Great ideas 👍😊
I used the old vape battery’s in solar outdoor lights.

Cadbury do make some wonderful lipo storage tins, don't they?!
However, a big bundle of little LiPos does add up to a significant fire hazard, even stored in a tin, so I am probably pushing my luck.
I have well over 100 of these little batteries, i want to make a battery pack for an electric skateboard with them. Do you think thats doable?
Your main problem will be safely charging them.
@@GrandadsOtherChannel Battery Pack - 20R 10S2P

Voltage: 36 V
Continuous discharge current: 30A
Power: 144 WH
I'm not sure if I calculated correctly but the little batteries are 850 mAh 3,7V 3.145 WA, so I would need 50 or so to make a battery pack of similar capacity. Is charging 50 of them more doable? If so how long would it take to do so safely. How would you go about doing this?
@@broek6075 the short answer is that I would not want to give you advice on such a project. I am sure I have seen videos showing large packs made from multiple cells, so I am backing out and leaving you to do further research. Good luck. I am confident it is technically possible, but to do it safely may end up being quite expensive.. You may have to build your own dedicated charger.
Brilliant!!!
Thanks, it could be improved, but it works for me 😊
why is the disposable battery disposable if its using a lithium ion battery when those can be recharged?
That is a question for the manufacturers, not me. I am sure it will be justified on a cost basis.
Could you experiment this with vape usb charger itself.
Most of the vapes I find do not have USB chargers. If you did use the charger from a vape it might overheat if you use it to charge 3 batteries in parallel like I have them here as 3 batteries in parallel will be drawing 3 times as much current from the charger. In addition, if you wanted to use it as a power bank like this, you would still need a voltage regulator circuit and a standard USB output port. On the other hand, if you just wanted to use the single cell on something like a small RC car or boat, then the onboard charger would be fine. I do have that in mind as a project and I have collected 3 or 4 vapes that have the charger circuit in them. I just haven't got around to actually doing those projects. I did do some videos where I used a small charger module that I bought off eBay as I hadn't found any vapes with the charger at that time. Here is a very simple example th-cam.com/video/Cx2ogpXkadg/w-d-xo.html and th-cam.com/video/nyqQehP1cNI/w-d-xo.html
Hi how about making a power bank using 2 18650 batteries and extending your 3d printed charging box best regards
Haha, the powerbank I pinched that circuit board from was an 18650. The purpose of this video is about making use of vape batteries. Yes, you could 3D print a box to hold 18650s. If you wanted to use 2 18650s in parallel, you probably want a different charger board, as that one is designed for a single battery. It would probably work, but it might take longer to charge as the current might limited.
this video rules I've wanted to do this for a long time. I'd like to chain together like 20 3.7v lipo batteries from my used elf bars to make a solar powered web server, but i've been putting it off because I'm afraid of the fire risk. if I put 100 ohm resistors between them will that be safe? should I make a little busboard to connect all of them to before they go into the controller?
So you want to put 20 in series 🤔 to get 80 volts? But you would only have the amphours of the single cell. It would only be as good as the weakest cell in the chain. In series, the voltage adds, but the capacity doesn't. A 100 ohm resistor between each one will drop the voltage. I have no idea what sort of controller would balance charge 20 cells. It sounds like you might end up spending more money DIY than you would buying a proper one. Having said that, check out Julian Illett's channel, he does lots of solar related stuff.
You might find this video by Toy Hacker helpful regarding building your battery th-cam.com/video/iDuUVUvNuOg/w-d-xo.html
@@GrandadsOtherChannel I guess I mean parallel then? I want to increase capacity not voltage.
@sammiecortese8439 yes, that is why I put these 3 small cells in parallel. I increased the capacity whilst keeping the voltage the same. If each one is 500mAh, the 3 together should be 1500mAh 👍
How many am i able connect them? Is there some risk to adding more mAh?
I'm sure someone already made this comment but storage of batteries like that is asking for problems. I love collecting the same batteries myself but storing them that way is a major fire risk as I'm sure you know. Someone else may not though so keep charging and be safe
I think you are right, there are plenty of comments to that effect, including many by me 🤣👍🏻 You also help to highlight the crazyness of people who just discard them in the street. One on it's own catching fire will probably not be a problem, but in the right surroundings it will catch something else on fire and start a chain reaction. When you have lots of them stored together the issue is multiplied. However on the other hand. They do not catch fire unless they are damaged or they are on charge or being heavily over discharged. So storage itself is not the issue.
I want to make a 12v battery from these batteries for solar, but i dont know how to do it safely so it doesn't melt when they're charging and discharging
Yes, if you don't have the electrical knowledge, you could cause a problem. Solar charge controller modules are available, but you would need to know the charge rate required for the batteries you have so you can buy the right one. You would also need an output circuit that would convert the battery voltage to the output voltage you need for whatever it is you plan to power with it.
Great video
I’ll be interested to see if you can make a larger pack with a BMS and a 2amp output for charging of phones
I have loads of these batteries that I really want to make use of
Yes, you could do that. The BMS modules are available online from eBay and other similar stores.

Buiscuit tin and lithium batteries can go electroboom
If you short out any battery it can overheat and potentially cause a fire. It doesn't need to be a LiPo. SO don't have the terminals unprotected when you store them. They don't even need to make contact with a metal container, they can short out to each other.
I guess its a faraday cage great 4 protecting you batteries from emp i suppose
The cells can output max current of about 3A from datasheet i found and cut-off voltage ⚡ at 2.75v and max changing voltage of about 4.2v i tested the battery with 2.1Amps when fully charged when it went to 1.35A at cutout voltage of about 2.75v because i tested it with resistor of about 2ohms and they test i got was 550 mah for 500mah battery whenever i tested again i got about 485 mah so i i recharged it about 5 times i believe i changed it with about 1A i had the battery for months and i not really sure what to do should i see how fast i can change it 🤔 i would use resistor lead's has Fuse's so they will disconnect the cells whenever current of about 4.5A they did whenever i tested so i think we should use fuses on vape lipo batteries i would say anything like 22 or 20 should be fine for about 3As would not draw more current than 3Amps has it will be dangerous and if cell was 500 mah and rated at 3A it would power it for 6 Minutes doing it so at least for peak current of 3A right i think its safer to do 2c has most lipos can do least 2c fast recharge = less waiting time i dont know maybe add bms but i wouldn't has they can be used in changer what will do it sorry if i am typing in too much
I think i would of tried to balance or test them slightly before parreling them to avoid exciting fireballs 😀 , Sometimes it makes you feel like some kinda tooth fairy collecting all these cells 🙂
So it's a 4.5 volt power Bank ?
Lipo batteries are rated at 3.7 volts nominally. Fully charged, 4.2, maybe a bit more. But the circuit board is set to output the standard 5 volts in the USB port.
And here we see the new generation. No longer will cookie tins contain sewing kits, no! They will now contain disgarded vapes and other electronic miscellany
The only problem with that is the fire hazard of the vape batteries ☹
Whats that little port called?
I'm trying to find a 2 way usb c port. That draws power to charge and expels power to give charges. But no matter what I search I just get showed those boxes you plug into the wall.

I want to make all my tv remotes, garage door opener remote everything rechargeable
My problem is the remote is 2 triple A's which is 3 volts or watts but all these batteries are 3.7 will that .7 hurt these remotes?
Not gonna answer so I will assume you would say a buck or butt connector to step down the voltage.
I have just got back from holiday, it will take hours to catch up. A LiPo battery is 3.7 volts "nominal" rating. Like any battery, including zinc carbon batteries, when freshly charged they are a higher voltage and as they discharge they reduce in voltage. A "normal" zinc carbon 1.5 volt vattery can be nearer 2 volts when fresh out of the box. To allow for that, the circuit board designer will have taken that into account, so you have a little flexibility. However a freshly charged LiPo battery is over 4.2 volts, plus it will stay at that voltage for longer, so that may be too much of a jump. A buck converter would be a sensible option unless you are a gambling man. Buying a bunch of buck converters of eBay is probably cheaper than buying individual voltage regulators and building your own circuits.

And using a buck converter in this video -
PART 2 6v Lightning McQueen with two 14500s. I seem to be doing a run of videos using these 14500 LiIon batteries. This one gives an extra challenge because it starts with 4 AA batteries, so expects 6 volts, which does not easily lend itself to using 3.7 volt Li-Ion batteries.

Great vid would anyone like any of them i have a fair few vapes, half a carrier bag full im uk based just cover postage ill send you some they contain the retangular flat battery 550mah if i remember correctly
👍
just playing devils advocate and you know my electrical knowledge is minimal, are they difficult to hook up nose to tail? so you could reuse some of the tubes. It would be a handy thing to hand out in either case.. back in the days of yahoo and the deviant art pages we made "throwies" just an led taped or glued to a button battery, some people glued them to magnets, some used flashing lights and some got added to urban gorilla gardening balls.. a piece of string with a weight could get them on the wires... not very eco friendly but..... make some up and put them in odd spots during your walks and check them every so often and recharge them.. I need to get out of here, my deviant mind has 100 ideas each branching off likea hydra.... lol
You could certainly let your creativity run wild if you got involved in these. You could solder metal plates on each end to help them make good contact nose to tail. The existing tags are not really suitable.
😂😂😅😅😊
That was probably useful, if it hadn't been so quiet I couldn't make it out at max volume. Isn't it possible to check these videos before posting them?
I have no trouble hearing it

Good luck with your channel 👍
@@GrandadsOtherChannel Thank you. I initially got 1200 subs in the first month. Then I upset TH-cam and they shut me down. So I'm starting again.
very dangerous and can catch fire and parallel means they DISCHARGE!!!
Yes, Lipo batteries can catch fire, and yes, if one cell is faulty it will upset the others. It will do this, whether it is in series or parallel. However, this happens with other battery types, not just LiPo. All batteries are potentially dangerous. You might have noticed phone battery fires have been well reported, not to mention Tesla car fires. If you do a little research you will find people starting fires with ordinary zinc carbon AA batteries. You will find a playlist on LiPo fires if you check my video description.
@@GrandadsOtherChannel also they won't retain a charge as the are gonstantly discharging being parallel. Also vape cells veru dangerous as very poorly made and no protection circuit.a law should be passed to make them illegal.
@esecallum I prefer to speak from experience. These powerbanks I have made have been in use for about 6 months now. What is your experience in this area?
@@GrandadIsAnOldMan I have seen thousands of videos of battery exploding or catching video. Also terrorists could collect these and destroy an entire city block.
@esecallum the youtube videos are staged. Perhaps you are unaware of what click bait is. Like I said, you will find a playlist in my video description covering lipo fires. As for terrorists, sugar and fertiliser are all they need. I am afraid that watching videos on TH-cam does not count as experience, although it is possibly a step up from tiktok.
Do they leak I have multiple will the foam pad leak and ruin the battery
The batteries don't leak.
Neat power bank G 🚗🚗🛞
Thanks, I think it turned out nice 😊
Nope. I got given a load of these discarded vapes. There were basically 2 kinds: a small square shape and the long cylinder which you have there. Unlike what you found, I found that the small square ones ( labelled LOST MARY ) had mostly a soft casing ( LiPo ) whereas the long cylinder had a hard-case cell (which had two prongs one end and looked like a capacitor ). However, both types of cell were the same thing: they are a '13300' Lithium cell with a 350mAHr capacity. The hard-case type are easier to work with because the contacts of the LiPo type are difficult to solder to and it's all very fragile.
Are you connecting the cells directly to 5V? This is very bad and will wreck the cells. Worst case is it will catch fire.
BigClive went into this in detail.
Good morning, Bruce. I guess you commented without watching the video. I clearly show the battery management unit that I use. It takes a 5v supply and converts it to the right voltage and current to charge the cells. I explained that and provided details in the video description. I also reference bigclive and include his videos in my related playlist. As for 2 kinds, you must live in a small place, there are dozens, if not hundreds of different sizes and shapes. The capacitor style are fairly new on the scene, and I have done a video on them, again referencing bigclive for further detail. I strongly suggest that you read my video description.
@@GrandadsOtherChannel fair point, well made,.
