How to use 3.7V Battery to Power 5 Meter 12V LED Strip in 2023

- If you are looking for ideas to use leds or 12V led strip to light a area far away from AC power source than you can use this method. You need a module called "Step Up Down Converter DC-DC Buck Boost" or "Boost Converter". You need this module in order to make this work.
You just need a 18650 battery that has more than 2Ah (2000mAh) and a Voltage regulator to power the LEDs. If we want more ON time for the LEDs you must lower the voltage and also check how much current we are using as well. Remember the lower the current being drawn from the battery the more hours you are able to use your LED strips or LED string lights. Lower voltage and current also lessens the brightness of the LEDs.
In conclusion the brighter the LEDs the more current is being drawn from the voltage. Lower the brightness you also less the current flow. If you have multiple same brand, same capacity batteries in parallel than you have more time to spend with your LED strips.
Note: Its easier if you just use a powerbank and just use a usb cable that has the positive and negative wires attached to the boost converter if you can't find a 18650.

I suggest using the MT3608 DC-DC Adjustable Boost Module, not the buck boost converter in the video. Thats because the one in the video has a cut off voltage of 3.8V which is not low enough.
The MT3608 DC-DC Adjustable Boost Module has a cut off voltage of 2V but don't worry that is what the battery protection board is for.
I have a boost module like that one and is rated for 1.5amps, which is not enough to handle the whole strip at full bright, it will get hot or dim the lights
Yes you are correct, it happens to the buck boost converter as well that I used in the video. 2 batteries in series is better or 3 is much better.
@@TaylorSoloaiJR just tested paint two small strips (50cm each) in parallel, and at 11v the light is bright enough and the boost converter doesn't get hot. Now the issue is the protection board. The one down here doesn't work since it's a charger nos a protection for a load, and needs to be powered to work. I think this would be better with a BMS boats that also does the balancing when charging amber discharging having more than one battery in series.
@Taylor Solai I had a question ie I have a 42 IR led lamp requiring 12v 1a power supply. So with the method you used to up the voltage to 12v, can I do the same or should i use 2 18650 batteries each 3.7v for my case?
Any help would be appritiated.
Thank you
@@RiO-kq6vz with two batteries, you have more capacity. In this case 2000mAh means 1,2h from 100 to 0%.
so helpful this brought me so much closer to completing my project thank you!!!
Glad I could help!
Huge Thanks to you !! Precisely the video I was looking for, since around 5 years ...
It's good to hear it helped. Thanks for visiting.
You guys can just also use the powerbank alone with the buck boost regulator. Just need a USB cable cut off the end and connect the wires correctly to the regulator.
Thanks for this useful explaination ! Liked n Subscribed ! 👍❤
Thank you, I appreciate the support.
Hello budy, how are you? Very good your video, congratulations!
I'm trying to connect a Ring light 12v 3.5a, which works connected to electric light, on lithium batteries, any suggestions on how to do it?
I am a bit stumped, but I have an 18650 going into a MT3608 to drive it to 12v. Then I take that to an XL4015E1 that I set the max voltage to 3.7v and current of anything to light a 3w led. Works but why am I being limited to about 270ma? I remove the LED and measure the current directly (looks like a direct short to the XL4015E1 and how you adjust it) the current is back to where I set it. Where in the world is the issue? If I have it going from the out terms but going through the led I don't I am stumped as I said.
I included the charger port for a build but now i have something that only switches on when it's plugged into the mains.
Great video and very helpful for a project i am working on. Can you advise the brand or more detail on the TP4056 you have used. I am intrigued by its configuration offering terminals for charging the battery and seperate terminals for the power out to the led array. Thanks in advance if you can help.
I actually learned a lot about this board by studying its datasheet online and also watching other CZcamsrs.
When you are buying one just make sure its the board with the battery protection. The other version does not.
I from India🇮🇳😇
Please help me I use 3 battery the same with you 18650 for the same led with you .. I wanna calculate how many hours will say with me ?
liked your video, would this also work with a solar pannel wich produces 28W and 5v ?
Sure, you can use that to power the LED strip
Hi there, interesting video.
I'm looking for led strips that I can use to light up some Lego models. I have seen 3V Led strips working with 2 button batteries (CR2032). Apparently it can even work for 2 days in a row (but I doubt it).
My question is, can you use a 18650 battery to expend the running time or is the voltage too high for such 3V strips? Can I also add one one these modules to the circuit to recharge the battery?
What about putting 2 AAA batteries in series, that way the battery box could be thinner?
The goal is to get a very dimmed light, I really don't need a full power bright lighting. It's just for ambiance. So would I need an extra module to also dim the light to a minimum?
My current project is for a Lego Millenium Falcon back sub-light engine, measuring 30 cm long and probably adding one Led strip part (they are cuttable every Led - 60 Leds / meter) for the gunner and another one for the cockpit.
Thanks
The module that I used in the video can also lower the voltage, so in your case 3V. The only problem with this step up and down voltage converter is it only works starting at 3.7V, so below that it will shut off.
You can run it with only the AAA batteries but you probably need a BMS board to protect the cells from being over discharged but you need to find out how much capacity the batteries have.
Honestly for me Ive been using li ion batteries for my projects, you can even get them for free from old laptop batteries. You've probably seen how they salvage them from other CZcams videos.
they don’t want you to connect another 5 meter LED strip to this cuz that would require I^2 times the amount of current to apply through out the whole 10 meters length, and that's why
Great work. How long does the battery last when the LED is at full brightness?
I haven't tried it on full brightness for too long because the voltage regulator was getting super hot, but adding another battery in series will be the best option rather than just using one.
@@TaylorSoloaiJR I see. I'll try that out. Meanwhile can I add a heatsink to reduce the heat from the voltage regulator?
The boost module, you think I could salvage one from one of my old vape box mods that has variable wattage? If so can you make a video showing how?
Not possible as they are regulated and timed
Boost converter are only about 2 quid
Can you show how to do the same but with 3 or 4 batteries? I mean with the protection board, I have more batteries but the charging is done in parallel while the discharge should be in series, and I'm not sure how to do the connections.
Their are BMS boards made for 3 or 4 batteries but that means you also have to buy a charging adapter. I'll try and see if I can make a video on how to do it.
so how long will it power those led batteries for? this is very cool
Depends on what power source your asking about.
The 18650 by itself can power it up to 2 hrs.
Serial connection of 3x 18650 should be enough to?
Yes you can connect them in series with a BMS to protect them, only problem with this it will exceed 12V so it will lessen the lifespan of your LED strips.
Taylor Soloai Want to ask u,How much long time will running full 5M strip of leds with 2x 18650 5000mAh in series with this buck booster? Thank u for answer
As I explained in the video, it depends on how much current is flowing from the batteries to the buck/boost converter.
The brighter it gets the less time the LED strips stay ON, but I would not use the buck/boost module because it will automatically shut off when the batteries goes down to 3.7V
I've been looking for a way to put an led strip on a few quadcopters but it needs to be light and easy since I'm an idiot. I don't even know what components to look for. I'd like to power a 12v strip with a 1s(3.7v) li-po.
eBay has some smaller "step up voltage regulator' that might work for your project. Smaller than the one in the video, just make sure to check the specifications first before buying.
hi. if i use Non-rechargeable batteries its necesary the lithiu battery charger module?
If you use Non-rechargeable batteries you don't need the battery protection board.
I suggest you use the MT3608 DC-DC Adjustable Boost Module, because the cut off voltage is 2V. So if its below that it won't work anymore.
I have several 18650, 2200 mah, 3.7 volt, 35amp high drain batteries from a e-cigarette vape device. My question is can I use a 3 slot battery box which would be close to 12 volts to power the same led strip?
Yes you can, I tried it before and it works. My only concern is that it will lessen the lifespan of the led strip.
I want to wire it with a switch for the inside of my gun safe. Like a refrigerator, door opens, lights come on. Should I use a BMS or a fuse? Will these led strips give enough light to illuminate the inside? Thanks for the info.
Hi friend nice video i have a question i have a lot of 18650 batteries bout i was trying to doing that with 4 aa batteries that was giving 5.04 v bout that not works any idea why sorry for my english 😅
Were you using the step up step down voltage module that I used in the video?
Current not supplied for a double connection
u can connect it in series they say that coz u need more amps on ur power supply and u need to add voltage adding wires for voltage drop
Yes you are right, connecting two in series is better but I just want to demo that you can use lower voltage batteries to power it but with with less than 12 volts.
@@TaylorSoloaiJR ahh I see but I just came across ur vid now ima try the exact same thing u did but will multiple batteries so it should run about longed
Do you use salvage 18650s or do you use the new batteries?
Just wondering what others use for their projects.
@@TaylorSoloaiJR I got a few new batteries but I also got some old ones ima try with both
This is also a good idea to run a modem or wifi router
i want to know a name of cable which you use for connect to power booster and led strip
Its just speaker cables, nothing special
Can i use 12volts Solar panel to charge the battery?
No, you need a 4.2V battery charger
Great video. But I could use some help.
I had a DC buck converter laying around, but it seem to only be able to step down the voltage. input is 4 volts, output can only go up till about 4.2 volts. what could be the problem here? Do I need a differen buck converter?
Buck converter can only step down voltage, you need a boost converter.
@@TaylorSoloaiJR Thanks! I'm ordering some.
if i use a 5000mah power bank for a 5m 5v led strip, how much would it last?
I'm not sure because I never owned one and it also depends on the color of the led strip.
Hi, I've made a project just like your video...I did a lil mods by put a switch between the module and the led, so I can turn it on and off easily... but turn out my battery always dramatically drained when I turn the switch off, so the led doesn't lit up every time I need it,,, then I had to recharge the battery so often.. what is your suggestion? or I missed something on the built process?
You need to put the switch between the battery and the module, because in your project even though the led is turned off the module still uses power. That's why your batteries are draining.
@@TaylorSoloaiJR uhh.. I see.. so thats why.. many thanks sir..
Would 3 of these batteries work without the board?
Yes it should be fine, but just check the specifications of the led strip if its okay to use more than 12V since the 3 batteries will give 12.6V when they are fully charged.
@Taylor Solai I had a question ie I have a 42 IR led lamp requiring 12v 1a power supply. So with the method you used to up the voltage to 12v, can I do the same or should i use 2 18650 batteries each 3.7v for my case?
Any help would be appritiated.
Thank you
Yes, you can use two 18650 batteries. Putting them is series is recommended. Just make sure you have 2S BMS for your batteries to protect them from being over discharged.
Do you mean 2 series charge module?
BMS?
Do you mean this--
XR HX3S 18650 3S 12V 25A BMS Protection PCB Board Lithium Li-ion Battery.
I found this on amazon.
Yes, those modules help with both overcharge and over discharge.
Thanks a ton for your help.:)
Hey man one last thing, in your case you used a single18650 battery holder and so connected only 1 of those blue units to prevent over discharge.
However if i use 2s or 3s batter holders how many would i need to connect and in what manner? Like 3 in series to each other or how?
I have a 144 led 5V strip. Will a single 18650 cell (samsung 25r with 2500mah 20A continous discharge) be able to give out around 10 amps when boosted to 5 volts?
I don't think that 5V led strip will pull up to 10A, should be lower. You could just use a powerbank. Since it outputs 5V, just need to find out how much mA it pulls. Its a lot easier and less work.
@@TaylorSoloaiJR I'm going by the official listed power ratings by adafruit. They say a 144led 5V strip would consume 43 watts (8.6 amps @5V). Here is the link. Please help me out knowing what sort of portable pworr supply can I do for this :) thanks.
learn.adafruit.com/adafruit-neopixel-uberguide/neopixel-strips
@@Alamini96 the module shown in the video won't work with the lights you have. Because 8.6A will be too high for it and its going to shut off. Unless you try using it at a lower voltage (which means the brightness won't be as strong) and get lower amperage.
Can we use this method with 3.7 volt li-ion lithium battery ?
Yes
hi. can i control the WS2812 LED strip with arduino using your method( video) as external source to power the strips?
Sorry i know nothing about Arduino, hopefully someone in the comment section can help out.
Taylor Soloai thank you..no worries ☺️☺️☺️
It's late sorry, but answer is no, WS2812 take 5V, although the method is the same.
You have a link for the buck boost regulator you use.?

@@TaylorSoloaiJR thanks, i see that you turn it on with the charger? Is it also possible to do that with a button switch?
@@TaylorSoloaiJR I want to use this module in a clothing rack with a motion sensor. Zo it has to be as small as possible for me with the batteries. this video is perfect
Hii sir what power is required to light a single led from a led strip light which u have shown in this video please help me sir I have a project pending
Your videos are very helpful 👍 sir Liked & subscribed
Sorry I don't have the answer for that now but I will get back to you after I run the test.
Also thank you for subscribing.
My led strip came with no remote or power and just 2 cable with opening in the end like yours. Is this the only way of getting power to the led strip
Yes, those are the cables to deliver power to the LEDs. Do you have the 12V or the 5V LED strip?
Taylor Soloai 12v
I hope you can help me sir,i want to use 18650 battery to power up 12v 90 watt electrical component for 7 hour daily for my little food truck.can you teach me what to buy?I really appreciate if you can help me,please.Thanks in advance.
Does 36v 100000mah 18650 battery will do the job by adding a 36v dc to 12 v dc ?if it can,how many year approximately,it can use?
I'm also ever planning to buy a 12v 80ah gel battery to so the job but i cant find a good gel charger for it in my country.
Can you also add a switch to turn on and off the LED Strip
Yes you can, make sure it's between the battery and the voltage boost module.
Will work on it. And i have been trying to add a few cells to but it is not working any suggestions on modifications i can make
Adding cells in parallel or series?
@@TaylorSoloaiJR added them in parallel. or which one would you recommend
It's better if you put two of them in series, unless you have three then you don't really need the buck boost converter.
Don't forget you're going to need a BMS for the batteries in series.
Can you connect 3x 18650 in series to give you the 12v and quite abit of mah? What do you have to keep in mind if this is possible?
3 18650s in series will give you 12.6V which is okay but it might shorten the lifespan of the LED strip but the good thing about the buck boost converter is if you set the voltage to 12V it will stay there OR you can just charge them only up to 12V, just don't forget to use a Battery Management System (BMS) board to protect the batteries from over discharging.
So you won't be increasing any mAh from connecting them in series but if you need to increase that then you need 3 extra 18650s. Three pairs of 18650s in series (2P 3S battery pack).
I hope that makes sense
@@TaylorSoloaiJR , this helped alot thank you! On Average whats the amp requirement for LED to be on full power?
If I know this value (im sure each brand differs) can I just add them up with the amount needed for the task and ensure my battery can handle discharge rate on top of using a Battery monitor circuit?
I'm not really sure because their are different LED sizes so you would have to do this on your own, just follow the diagram in the video and you should be fine. That's if you already have a multimeter.

Hey, do you think that with such a regulator and multiple batteries in parallel it would be possible to power up a 5m 2812b Led strip at full power without burning everything ? (18w/m)
Thanks !
You need to get one with a heatsink already attached, the one in the video will eventually shut down if it's over heated from the heavy load
@@TaylorSoloaiJRwow, what a quick response 😅
Thanks a lot !
You're welcome
Voltage drop end to end
Just don't use it at high voltage

এটার দাম কতো?
The boost converter cost about $1 USD
Fast low bat
The higher the amperage the faster it uses the battery capacity, use a 5V led strip instead
Can I connect a 3s Battery 11.7v to the TP4056 charging moudle ?
No, you need a 3S BMS for that.
Hii sir what power is required to light a single led from a led strip light which u have shown in this video please help me sir I have a project pending

@@dakshpatel2409 sorry for replying late but I have no information about how much power a single led in the led strip uses but from my experience the shorter the led strip the less power required.
