Small powerbank from Vape batteries

[@groggers]

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.

[@meltedcheese1091]

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

[@billyjoegilmour95]

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

[@Palmit_]

heya @@meltedcheese1091 i'm looking to do similar as you did, 12v. what charging / bms boards did you settle on?

[@0eroOverride]

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

[@jantrisko]

This video is a tutorial on how to set fire to a house. When connecting batteries in parallel, it is advisable to have them charged to the same voltage. The use of very undervoltaged cells can lead to a very small capacity of the power bank. Otherwise a good idea, but very terrible execution. I recommend not following such a procedure.

[@groggers]

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.

[@meetjeric]

you are such a good advocate of recycling those disposable vape batteries from them being thrown into waste

[@groggers]

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!

[@billyjoegilmour95]

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 ❤

I've rescued hundreds of these batteries from disposable vapes. They always charge OK, using a TP4056 charging circuit (with protection). They normally start charging at around 45 to 50 mA, and gradually fall to around 8mA after two and a half hours, having taken a charge of between 500 and 550 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

[@GrandadsOtherChannel]

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.

[@Louis-yy6ge]

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.

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

Hey! Thank you so much for the advices and knowledge you are sharing with us through your channel, very interesting. I've tried a small project following this video that i would like to discuss here about recovering vape cell from street and then building a new battery pack for my vintage camcorder (needs 9.6v). I've soldered three vape cells (3,7v 2.035wh each) in parallel after charging separately (4.10v each after the charging process). But when i put the three of them together with a TP4056 module, it's still giving me 4.10v! I don't understand this logic and i would like to ask you some help. Thank you so much in advance!

[@GrandadsOtherChannel]

Unless I am misundertsnading what you are saying, you have them in parallel. When you put batteries in parallel the voltage stays the same and the current capacity increases. If you put the 3 batteries in series, you would get 12.3 volts (3x4.1v) and probably kill your camcorder. You would need a voltage regulator to limit the voltage to the 9.6 volts that you want. The TP4056 chip is a charge controller that takes care of charging the batteries, it does not regulate the output, although if you have bought one of the TP4056 modules on a small circuit board, that may include extra circuitry that monitors the output voltage and prevents the batteries from being over discharged. Talking of voltage regulators, you can buy small modules with an adjustable output. They are known as Mini DC-DC step down converter volt regulators or "Buck Convertors". Buck = drop the voltage as opposed to "Boost" Convertors that increase the voltage, which would be another alternative with your existing 4.1v output.

@@GrandadsOtherChannel THANK YOU so much, i didn't know about the difference between parallel and series layout; i'm kind of a newbie in electronics, so thank you for this basic lesson.

[@suneeljutla]

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?

[@GrandadsOtherChannel]

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.

[@swaroopkunduru8557]

Could you experiment this with vape usb charger itself.

[@GrandadsOtherChannel]

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.

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

[@GrandadsOtherChannel]

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.

[@EmeliaBelle]

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

[@GrandadIsAnOldMan]

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.

[@avocadoarms358]

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?

[@GrandadsOtherChannel]

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 KZbin 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.

[@GrandadsOtherChannel]

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.

Are you using a li-ion charger to charge lipo batteries? I thought you were meant to change one of the surface mount resistors?

[@GrandadsOtherChannel]

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.

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.

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.

[@GrandadsOtherChannel]

What little white connectors? Give me a time stamp so I can see what you mean?

[@addictedtotreasuretrash108]

Hej Sorry. 6.20 the white connectors you have on the cables so you can connect to your model car. I have no idea what they are called or where to find them Thanx.

[@GrandadsOtherChannel]

OK. The white connector is on the balance lead. That connects to the charger so it can measure the values of each individual cell. The red connector is the one that connects to the car. I will give you a couple of eBay links to show you what I am talking about. NOTE: I AM NOT ENDORSING THE SELLERS, just using the links to show you what to look for. You should do your own search to find the quality, quantity, and price that you want. Other online stores like Amazon, AliExpress, and Bangood will also sell them.

Hi how about making a power bank using 2 18650 batteries and extending your 3d printed charging box best regards

[@GrandadsOtherChannel]

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.

[@zeez4178]

So it's a 4.5 volt power Bank ?

[@GrandadsOtherChannel]

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.

[@steve64464]

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 🙂

[@aaronali822]

Buiscuit tin and lithium batteries can go electroboom

[@GrandadsOtherChannel]

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.

[@greysunomain]

Whats that little port called?

[@greysunomain]

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.

[@GrandadsOtherChannel]

There is an eBay link in the video description to the type of board I was using, When I click on that, eBay offers me other similar items including this USB C option www.ebay.co.uk/itm/225601822640 I am not recommending this seller, just using the listing as an example. I am sure if you search you will find a variation in prices etc.

[@GrandadsOtherChannel]

Reading the listing description on that item, I DO NOT think it will do what you want. It says the USB C is the input. It does NOT say you can use it for output.

[@greysunomain]

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

[@GrandadsOtherChannel]

Yes, you could do that. The BMS modules are available online from eBay and other similar stores.

[@billyjoegilmour95]

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 want to make all my tv remotes, garage door opener remote everything rechargeable

[@dogcreek-customs5168]

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?

[@dogcreek-customs5168]

Not gonna answer so I will assume you would say a buck or butt connector to step down the voltage.

[@GrandadsOtherChannel]

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. Here is a video I did 6 years ago on the subject of battery voltages - Comment reply - How many volts from 5 x AA batteries? kzbin.info/www/bejne/n52yZoaMibh5d7s Grandad's postbag 200106 DC DC Step Down Buck modules kzbin.info/www/bejne/eF7CaXeKpM6lisk 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. To make the voltage match I add a mini Buck Converter module and adjust the 8 volts from the batteries down to 6 volts for the receiver. kzbin.info/www/bejne/ZpfRnopnjdCmea8

I think you have a low opinion of an average Joe. Remember people are happy to put vapes in their mouths, drive electric scooters, and Teslas, and carry mobile phones in their pockets. Oh, actually maybe you are right 🤣

[@xentiment6581]

If you are average Joe, you are not being shown this video. If you are, you probably can do this. At the end of the day, cells like this are as safe as standard RC or Airsoft batteries with no protection circuits.

[@docink6175]

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

[@GrandadsOtherChannel]

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.

[@esecallum]

very dangerous and can catch fire and parallel means they DISCHARGE!!!

[@GrandadsOtherChannel]

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.

[@esecallum]

@@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.

[@GrandadIsAnOldMan]

@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?

[@esecallum]

@@GrandadIsAnOldMan I have seen thousands of videos of battery exploding or catching video. Also terrorists could collect these and destroy an entire city block.

[@GrandadIsAnOldMan]

@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 KZbin 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

[@GrandadsOtherChannel]

The batteries don't leak.

[@bruceclothier8238]

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.

[@GrandadsOtherChannel]

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.
