This video is 3 years old and still the best for wiring a battery and charger. Your ability to describe what is happening is top notch.
Thanks, I appreciate it. I've run a lot of training courses for all kinds of subjects over the years, and the main thing I learned as an instructor is to try and walk that fine line between explaining everything but not treating the audience like they're idiots :-)
@@SteamGeezerUK Yep. I am a teacher and that is a good strategy.
This is definitely my favourite of your videos. So many applications for a simple circuit. I can feel my build genes firing up...
Thanks, I appreciate it :-)
Literally what I needed for my first electronic project
I’ve been hoarding lipo batteries from various broken things for the past couple months, glad to find videos like these! got quite a few batteries from “disposable” vape pens, what a waste!! Perfect little batteries to power little leds in little sculptures!
Exactly. No point throwing away perfectly good batteries.
Thank you, thank you so much for showing me how this works simply and beautifully. Had a really hard time visualizing what was supposed to go on without your video.
I'm glad it was useful to you. Thanks for watching :-)
Right to the point and told me exactly what I wanted to know. Plus it didn't include the entire history of the battery. Great video.
I'm glad it was useful for you :-)
Your work is very good, I wish you success in the following and thank you for this information. Thank you
Thanks for sharing…exactly what I’m looking for on my projects
I appreciate the titan fall stuff ... thank you
Thanks, I appreciate it :-)
Excellent video thanks very much
Thanks, and thanks for watching :-)
Exactly what I needed 👍🏻
I'm glad it was useful for you. Thanks for watching.
Cool tips That was awesome you made that for your son Great job on it as well 🔥👍✌️
Excellent
Exactly what I needed
I'm glad it was useful for you. Thanks for watching :-)
Thank you
You're welcome
Love the sear kit man!
Great video. I just can't but help think that this is Igor from Young Frankenstein. Made the whole thing just that much more special.
Thanks. I think... :-)
@@SteamGeezerUK I actually meant it as a compliment. Your video is informative and the movie has one of my favorite characters of all time.
Thank you so much. Now i know how to use my 10000mah lipo....the only missing is the chaging board.
I was literally watching this while playing titanfall what a coincidence.
very good, thanks! next time maybe show you soldering! 10/10 video thank
Thanks. There's some soldering in some of my other videos if you're interested.
You can't use that to charge any battery up to 5V. Its a fixed 4.2V max charge voltage
Can I use a dc motor in place of LED
Sure, as long as the power requirements meet the battery output, you can put pretty much anything on there.
If the charging module is directly connected to the battery like in this video will it drain the battery?
Eventually, yes. It's a good idea to put an isolator between the battery and the charger if possible, but it's not always practical.
One could also put the main switch between the battery and the charger, but that means having to have it switched on to charge.
I used a setup like this in my display turntable, but in that case I added an isolator switch as well as the normal on/off switch.
9:21 OMG I was just watching Titanfall 2! Wow nice! You have BT!
One of my earliest 3D printing projects :-)
This is a Great tutorial thank you very much for sharing, I have used this TP4056 charging module before to charge my 18650 cell and they are great. I find this very interesting that you can also use it to charge the small quadcopter batteries because I have some how lost my charger. Just one question please, I have several different drones with different battery capacities! will the module adjust the charge rate automatically according to what battery I want to charge? For example 150Mah 500 Mah 800Mah etc. Thanks again for a Great tutorial... John :)
I use these boards to charge a variety of batteries, from 150Mah to 1500Mah, the only difference I've found is in the length of charge time. As long as you're not trying to charge a battery greater than 5v, I don't see a problem.
Thanks for watching.
Man was thinking for ages how to make a small cicuit for my diy track ir and I am so glad i found this. Normal batteries just don’t work for that.
How safe are lithium batteries? Because it will be pretty close to my head 😅
The TP charges at 1A. Is that too much curreny for a 250mAh battery?
great video, very helpful. Ive got a project that uses a 3s lipo 11.1v. Could i use this same circuit to charge a lipo, or what would you recommend? thanks
3 cells (1.2 V each) connected in series. How can i charge 3.6 V 1000 mAh with 5 V charger? Which resistor i will need?
The batteries I use are 3.7v, so you might not even need a resistor. I don't use one, but I'm honestly not sure.
Would this work in a rc car I hate using battery's there rubbish and I have loads of 3.7v batterys planning to use to so in all 7v of power output to the rc motors (can take 9v max) but want a way to recharge the car without taking battery's out
This precise setup, no. It will only output up to 5v so it wouldn't charge a 7.4 (2 x 3.7v) setup. However, there are charging boards that can output 8v so if you used one of those, then that should work. If you look at the linked video at about the 45 minute mark, you'll see what I mean.

@@SteamGeezerUK thanks dude I'm going to order the stuff next week sometime I'll post updates p.s liked a subscribed
thanks for the video!!. I wonder if I can use the same for 3.7v 1500mah lipo...........
Thank you dear sir , could you please let me know how much time it will take to recharge 3.7 v lipo 600 mah battery
I pulled apart a cheap Bluetooth speaker because it didn't work. I don't think it supported fast charge, took the battery out & rigged it up to a multimeter.
0.00v! Completely dead!
I salvaged the tiny regulator board, & a long copper foil strip, a long misty like cling film strip, & another strip , which I don't know what that is, might be a nickel foil strip.
The copper foil was blackened, so I cleaned it in vinegar & salt, could easily rub the black away to reveal shiny copper foil
the logic board has, a 5v charge circuit, a Bluetooth circuit, mono sound output with a headphone jack, & a mic.
I know it would work again if I rigged up 3x 1.2v rechargeable batteries .
The things I salvaged -
- Logic board
- Battery regulator board
- Copper foil strip
- unidentified strip
- 1x 3 watt speaker
I put the unidentified strip in vinegar, & it's turned the vinegar pink!
Great video. Where would I solder wires to this board if I wanted to add an EL panel? May I email you some photos of what Im trying to accomplish?
It would be tricky to run an EL panel off of a setup like this. EL panels need a driver to power them, it's basically a miniature transformer and inverter that boosts the 3v DC to about 100v AC. In theory you could connect the output from the charging board to the battery terminals on the inverter, but I honestly couldn't say if it would work or not.
Hi please help me. Can you keep the charger plugged in 24/7? Does it stop charging when full? I would like to use a lipo battery as back up in case of loadshedding
okay, one question so we don't need any step down DC-DC converter in between to convert 5v to 3.7v lipo. i am confused.
Do you have a guide to making those micro USB hub
3:33 ish?
I don't, I'm afraid. I would actually recommend buying them. I didn't realise they existed when I made mine, and the amount of time it takes to make them really doesn't justify it when you can buy them for pennies.
Here's an affiliate link to such boards on Amazon - amzn.to/2ZXIsIT - This is fine if you need them quickly, but if you're prepared to wait, you can get them cheaper from China on ebay.
Thanks for watching :-)
Great video, ive bought the usb boards, the batteries, im looking at some switches, i can see the wiring the board, but not the wires that go to the switch, a 3 pin one, which wires go where ?
Sorry for the late response - I just replied to your Facebook message.
@@SteamGeezerUK Cheers :)
Where do you get quality components for your builds. Thanks
Depends how you define "quality"... Pretty much all components are mass produced in China these days, and the factories that make them for the big players like Sony etc usually have some kind of retail operation so they can offer the same components but in much smaller quantities to the home market. Basically they use the scale of manufacture required for the big companies to provide cheap components to the rest of us, so technically you're getting the same quality of component as the big players, but whether that's actually true in practice is difficult to say.
There's a whole discussion to be had on the general decline in the quality of electronics over the last few years as people demand "cheap" as opposed to "quality". To answer your question though, I tend to just buy mine from ebay or Amazon and hope for the best.
Hey hello love and warm regards from India, I wish to know one thing this is a TP4056 circuit normally built for 4.2V that's the voltage for a Lithium ion battery, Lifepo4 or 3.7V lipo batteries have max full charge voltage of 3.7V so how can we precisely charge a 3.7V battery from a 4.2V charger without raising voltage of 3.7V to 4.2V. I wish to build a charging rack for lifepo4 EV cells rated at 3.7V 6A
Hi, i have a question, i want to implement this battery to be charged by a 5v solar panel, what is the best and safest way, does it have to be via this kind of pcbs? Is it a bad idea to connect the battery directly to the solar power to recharge, my idea is to have the battery auto charge on solar energy and operate the rest of the time when turned on
Honestly, I'm not the best person to ask about solar - I really know next to nothing about it, but if I ever figure it out, there'll be a video like this one. Sorry I can't be more help.
When I made a charger it expanded the battery is it putting to much voltage?
I honestly have no idea. The charger you use has to match the voltage etc of the battery, but if it's a bad battery, it may swell up. I'd leave it outside and away from anything flammable for a few days, and then dispose of it safely. Cheap batteries can be dangerous.
Can you yoo ene sis of leds on reaching battery?
May i ask if im going to use 3 led white which is 3v each and using 3.7 battery to power the 3 led what resistor should i use? Sorry not that techy 😅
Sir what is the name of pin on battery
How did you power the sound card with out button batteries, do you have a link to that video
There's a video here with one in it, but basically I just bypassed the battery holders and soldered power leads from the battery circuit directly to the soundcard - th-cam.com/video/BGVQY74WW3Y/w-d-xo.html
Hi there I'm interested of learning more. By any chance if you could help me with the 4410 Adafruit Micro-Lipo Charger for LiPoly Batt with USB type Type C Plug. I've read from Amazon at first comment 2 went well and from other went horribly wrong.
I don't have one of those unfortunately, but if I ever come across one, I'll do a video on it 🙂
so i am inventing a new lint remover that has two blades that remove lint and hair from clothing and fabric! I have sourced a few powerful 3.7 volt sonic vibrator motors and im wondering if my two AA batteries will give the 3.7 Volt sonic vibrator motors the best and most optimal power that they need? Have not tested it out yet, but i have a feeling these two AA batteries will not be the best and most powerful battery for the powerful 3.7 volt sonic motors! Perhaps, there must be another more viable and better suited battery system for these 3.7 volt sonic motors, right? Also, i know that if i decide to use a usb rechargable battery, this will dramatically increase my price per unit which is not ideal for me becasue i plan to sell this lint remover at no more than $20!
Any thoughts would be helpful
Thx in advance!
I don't know what the power requirements are for your motors, but AA batteries only put out 50mA (or so I'm told). A lithium polymer battery will probably give you a lot more than that (it's different for each battery, so I can't say for sure). You might also consider a single 18650 type battery. I would suggest trying it with AA batteries and see how it works. If you need more power, you might have to go for a bigger battery.
@@SteamGeezerUK so you're saying use the AA batteries in combination with the 18650 lithium polymer battery? if yes, how would the customer recharge the product? Would he have to replace the AA batteries and the lithium ion polymer battery?
Because i thought that all lithium ion batteries are rechargeable? To make things simple, lets say that i do decide to go with a 3,7 volt sonic motor, then i would just get one 18650 lithium polymer battery and if i need more power then i just add another 18650 lithium ion polymer battery? also, i dont think this would drive up costs because i am very confident the factory in China can get all these lithium ion batteries and sonic motors off the shelf or just buy existing lithium ion polymer batteries and sonic motors and from here, the factiry would just wire up the sonic motors to the lithium polymer batteries and connect it to an on/off switch and since i only have 1 vibration speed and mode, there would not need to be a circuit board or PCB, right?
and i forgot to mention the usb cable needed to recharge the product, this can also just be put in the package instead of making an entire complex charger separately for the product, right?@@SteamGeezerUK
im planing on using a 3.7v 600mah battery which I believe will be fine based off what you said, right? secondly can I clip the connector off and just solder the leads directly to the broad, or is there a need for the connector on the end of the battery?
That should work fine. As for clipping the leads off, that's what I normally do. The only reason I would suggest leaving the connector on if you can is that it means that if you ever need to replace the battery, it's a lot easier than having to desolder the joints, but if you're pushed for space inside your project, it's sometimes helpful to solder the battery straight to the board. Just be careful to keep the wires apart while you get everything together.
GET ON WITH IT!
May I please message you? I've been trying to find a way to recharge a Cozmo robot I got cheap and had some questions!
You can find me on Facebook and message me on there if you like - @Steamgeezer should find me on most social media platforms.
When you are charging the battery with the micro usb, is the led still getting power from the battery or from the microusb? If it's from the battery, is it harmful to both charge and consume at the same time?
I'm honestly not sure. If you connect an LED to the charging board with no battery, it will work even without the battery, but every time I charge the battery I always turn off the LED.
Is it possible to use a JRC B008 instead of the TP4056?
Can this charge a lipo and lithium polymer batteries. I mean not at the same time.
I'm not sure what you mean. Lipo is just short for lithium polymer, or did you mean a different type of battery?
I meant different types of batteries
How did you connect the output to on and of switch??
Where did you buy the Circut?
The actual charging board? That came from China via ebay. If you search for "5v micro usb charge circuit", you'll find them.
What type of switch did you use? I can't find switches compatible for 3.7 volt batteries.
I generally choose the switch based on where I want to put it, rather than any rating of the switch. All the switch is doing is completing the circuit, so at this voltage pretty much anything will work. Something like the ones at the link are rated to 125v but will work fine for this kind of thing - amzn.to/2EsO0W7
interesting video. how many 3.7v cells of what mAh capacity can be charged through the board in parallel and in series?
I've never tried more than one in parallel, to be honest. The largest battery I charged was 1200mAh, but I don't think the capacity would make a difference other than to how long the charge cycle would be, so I would imagine you could put as many batteries in parallel as you like. The batteries I use, although rated at 3.7v tend to output 4.4v when fully charged, and the charger outputs 5v, so it won't charge more than one battery. I did try to charge two 18650 batteries on one of these once, and it didn't work - I had to find an 8.4v charger for that.
As far as I understand you use a seperate module for each battery that you want to charge, They are very cheap to buy :)
Hey do you think if I exposed the wires on the rechargeable battery and connected it to a DC Motor (24 volts) that it would be able to charge the rechargeable battery?
Or since I saw that you used a usb recharger, if I connect the DC motor to that, would it be able to charge the battery?
I don't think the charging board has an incoming voltage regulator on it. I think if you put 24v through it, it would fry it.
I'd also be very wary of putting that kind of load to the battery without a voltage regulator. Lithium polymer batteries can catch fire and even explode if they are overcharged.
You can get variable voltage regulators that would drop the 24v to 5v, but I'd test it very carefully and be very wary of the battery overheating.
Yeah I understand, we’ll even though it’s a 24 volt motor, I’ll only be producing electricity by hand, which I tested before with capacitors and I believe after 100 rpm I was only able to create 0.2 volts, nothing dangerous; so that trial is just to see if I’m able to charge & let’s say it does work in the trial phase, would I be able to put 4 rechargeable batteries in series to provide a larger voltage to perform work or would using secondary batteries this way not be good?
Just wondering how legitimate my project can be with storing energy and using it at a later time
Thank you for your help!
where can i get the exact charging circuit
please it is urgent
There's some here on Amazon if you're really stuck for them - amzn.to/3ozRwBG
@@SteamGeezerUK thanks Sir
do you have the schematic in order to add that on my project
I'm afraid not, no. It's pretty simple though, just a switch, the circuit, the battery and a light.
so this little usb charger also converts 3.7v to 5v ?
This particular one doesn't step up the voltage, but in my experience most 3.7v batteries actually produce a nominal 4.4v. You can get charging circuits that have step-up transformers to output 5v from a 3.7v battery, but they're more aimed at charging mobile phones and such.
For small circuits, these batteries will generally provide sufficient power. For example, in the Titanfall 2 SERE Kit I made, one of these charger/battery circuits is powering two LEDs, one Epistar diode and a soundcard and speaker.

Hello sir the module is heating up
Sir please tell me
I'm not sure what you want me to say. If the board is getting hot, either there's too much power going through it or the board is faulty. I would recommend replacing the board.
Can i charge li ion batteries with this circuit
I honestly don't know. I don't see why not but I've never tried it.
배터리 충전기 있습니다 usb않아
Can i ask what is the output of the board ?
That's a good question. It's 5v and I believe the current is 1A.
Can I charge 4 3.7v battery in parallel series with this board
I honestly don't know. I don't see why not, but the charge time would be quite long I think.
@@SteamGeezerUK thanks for your reply
This circuit is specifically made for 1S batteries. As I read on web, you need one of these for every single cell(S) to charge them
What's the current rating of this charger
It's rated for 5v 1A I believe.
What is the charging time of this battery?
I'm not entirely sure, to be honest. Not very long though. I have one in the Glowstone diorama that the missus uses as a nightlight. It's on for about eight hours a night and she charges it about once a month for an hour or two if that helps.
The charging module get heat
Any electronic component will heat up in use. If it gets too hot, however, there may be something wrong with it.
Thank you
Where can i get the circuit board for this?
I buy them from ebay. Search for "micro usb charging circuit" and they'll turn up. If you don't mind waiting, you can get them from China for much cheaper than UK prices.

Hey #cool thank s for the info. ??? I am a bit stuck on a project. I need a long lite batery to cover 2 charger 5v for phone . also need to cover a mmptt S charger 🏃 att 12v . batery just die . your take on a good 5v to 12v lite batery I need at least 3h time to charge a normal Android 📱 + 5v 3w led camping bulb . Hey tha knives is So #cool
I'm not entirely sure I understand the question, I'm afraid, but a setup like this won't charge 12v. If you're after a charger for a phone and a 5v LED, I would suggest using some good quality 18650 batteries in parallel to give a good long life. This could be connected to a charging circuit to charge a phone and another output to run the light.
I'm not sure what the 12v part is you're talking about, but if you want 12v I would use 18605s in series and parallel to give a 12v output, a voltage regulator to drop to 5v and then connect to the charger as described.
I hope this helps, although it might be easier to buy one ready made - a lot of companies making camping chargers.
Yup, I'm high
Don't drive or operate heavy machinery... ;-)
Can you give me your charging board i will give you money
It would probably be cheaper to buy the parts from ebay. I would think the postage would cost far more than the parts themselves were I to send it anywhere :-)
