Thank you for detailed review and test. Using it as current limiter with 12v psu for powering up LEDs. Without this module, psu switched off due to current runaway. Now working stable with lower voltage and limited curren at 9.5v and 1.5A and not hearing up much.
Now this is what i call a great review! I did not expect this thing to be so clever. I will receive mine in a few days, cant wait to try it out. Greetings from germany!
I would like to share that I have some of these XL4015 CV / CC modules (bought thru eBay) and I made an auxiliary power supply and CAR BATTERY CHARGER up to 4.0Amp continuous, using this module, a 50mm fan and an older LAPTOP power supply (19V x 4.7A = 90Watt rated). It worked very well to provide 14.4V (CV adjust). However, at more than 2.0 to 2.5A (CC limit), the Output diode, Output capacitor, and inductor heated substantially (>70°C) - measured with IR spot thermometer. I solved that using a 50mm 12V fan blowing directly into the XL4015 module and even created a fan speed control, measuring the temperature with an 10K NTC (epoxy glued) under output diode area. I have set the threshold to 55°C for High speed (10Volts) if the module is more demanded, otherwise the fan runs continuous and silently at 5Volts. It works well up to 4.0 ~ 4.5A max, but to play safe, I limit the current to 3.5 ~ 4.0A max for long term use as charging a car battery, when I see the temperature control can still turn off the ”fan blower” over the module - proving the cooling it still has thermal safety margin. I hope it helps.
As the battery gets charged, regardless if you limit the current, the battery asks for less current because the battery potential gets higher, while the batteries internal resistance remains the same.. requiring less current as the battery gets charged. If there's no current limit the battery will ask for whatever the battery can handle depending on its internal resistance, ... So for the mp1584 buck it cycles and heats up.. but when I get near 100% the converter provides us current and gives a constant charge.. shows no more cycles of heating up.. I see this on the meter.. therefore I know that it is heating up and shutting down and then heating up again charging fast.. Buck converters taught me about battery charging.. buck converters are awesome because there's plenty of sources of free voltage.. batteries, solar panels, hand crank generators, wind turbines, hydro turbines, ... The buck converter takes these voltages and lowers them for us.. absolutely awesome. Love inductors and capacitors!!
I always use the 1/3 Amperage principle to protect the circuit from voltage and amperage drift. Plus overheating. At 5 Amps maximum rating according to the datasheets, that calculates to 1.666 amps continuous voltage and amperage output without drift. It has worked for me for 25 years without any problems. It lets me sleep at night. LOL
Again, that is a silly way to design for such low margins, and since you did not design this, is not applicable to these or other over-rated generic chinese modules. Nothing you own, including the computing device you watch this on, is designed to that wasteful standard.
@@stinkycheese804 How many Degrees do you possess? Do you even have a grade 12 Diploma? How much design experience in electronics engineering do you have? Don’t judge me when you don’t know what you are talking about.
@@robojax it’s so funny I just realized last night that I must have been watching Robojax and Watthour videos for months now interchangeably without realizing they were separate accounts! 😂 I was wondering, why did you decide to change / create a whole new account though ? Your videos are the best, so thorough!
@@robojax l’m subscribed to both! ❤️ I got one of these modules btw and love it. They are so cheap I think I’m going to put them on all my devices for voltage protection (I noticed my ESP connected to it runs cooler now too). Now I could use your wisdom : in either wiring two in parallel to support powering two 5V 3A 8 x 32 matrices on one power supply. Or finding one converter that can handle both panels. One of these Xl4015 modulels comfortably handles one panel. It handles two panels, if the displays are not full brightness. I’m a little concerned that someone might boost the brightness an hurt this buck unless I have two running. Either that or do you have a favorite converter that handles 6A? (searching your videos frantically now 😆)
Dear Brother Greetings of the day Fabulous way to describe each and every thing with database I appreciate your efforts I am working in central university in India
Thank you for the detailed review and providing chapters! Could have a "setting output voltage" chapter, as that was what I was looking for. But ended up watching the whole thing :)
Very nice explanation. I bought it yesterday and follow your steps. The module works flawlessly. But one thing you missed the Li-ion, Ni-cd, Ni-mh battery charging test. Can you explain it ??
This is not a charger. This is just a step down converter. If someone want to use it as charger, it has to be monitored constantly as this will damage the battery. Thank you for not skipping the ads and keep watching it. This will help me a lot.
But description shows it👇👇👇 This Buck converter can be used as a normal step-down module with overcurrent protection capability for various applications. It is used as a charger for various voltage lithium batteries, batteries, nickel-cadmium nickel-hydrogen batteries (battery packs), for solar panels, wind turbines, etc. This buck converter can also be used as a high power LED driver module.🤔🤔🤔🤔
I bought 5 of these modules; applying 13v input; output voltage is equal, i.e. always 13v. Voltage potentiometer does nothing to change output voltage no matter how many turns - on all five modules. I would recommend to stay away from these modules as apparently they're prone to component defects.
A yellow core is often iron powder core. If it is then the XL4015 is likely a fake because an iron powder inductor is no good at 180kHz. Check the switching frequency on an oscilloscope, it is likely 50-70kHz, in which case the XL4015 is a fake.
Hi, I looked at page 3 of datasheet for XL4015 datasheet.lcsc.com/szlcsc/1811081616_XLSEMI-XL4015E1_C51661.pdf and the output SW pin and it can't get current entering that pin. so it seems safe. but I have not tested it.
I have this module. When i input 12v dc then instantly full charge LED lights up and no output voltage develops. Is my device faulty? What's the possible problem?
Very interesting your posts in general and this latest one is no different. You did explain very well everything, but the Efficiency equation at time 7:50 could be clarified in terms of P-out (Vout x Iout) x Efficiency, or for required Pin, as I understood from your talk. Regardless of that I’m very glad to see all your effort to share in a very practical way and check its limitations. *** (integrating here past replies in 2020): P_out = P_in x Effic. Or P_out = (V_in x I_in) x Effic. Or still required P_in = P_out / Effic., that is what I meant.
Thank you for sharing your work and comment. Even though I have written "Input Power" and "Output Power" I should have been explicit to eliminate ambiguity. I can't fix that now unless to remove it that portion or re-upload the video again.
This happens to everyone. And I just realized that I did a mistake too: P_out = P_in x Effic. Or P_out = (V_in x I_in) x Effic. Or still P_in = P_out / Effic.
@Richard, I agree with you, thanks for noticing. Furthermore, I had observed this and made a reply to Robojax about 1 year ago, clarifying this mistake from my side, when I also elaborated the equations referring to Vout and Iout. To avoid similar misalignment of posts, I edited and supplemented my original post with the intended equations.
Thanks for the review! Do you happen to know what the two holes are for located next to the positive input? One is connected to the negative input, and the other appears to connect to pin 4 (VC) of the XL4015 , although that's just based on my continuity test. Any idea what that might be used for?
Thank you for this video! I purchased from Eiechip on Aliexpress some boards XL4015 5A for charging a lithium battery with two resistors and the output voltage is adjustable but the output current is not following the process shown in your video @ 12:44! Which component could be defective on these boards? The same issue with all 5 boards I purchased.
It would be nice if you had summarized the results V/A/ efficiency rate and instead of showing every test you would stress test at maximum settings ro show design failures of the converter and ways to improve it!.....
I don’t like positive buck converter the positive voltage is burn the mosfets like a resistor even with bootstrap driver I use only negative buck converter circuit I use a higher 5 amp motor with 12 amp surge and the negative buck work very cool
Thank you for this tutorial. My question is...can I achieve 18v and 1.7amps with this module. I have a 4s10p lithium battery pack and would like to power up a boom box stereo that takes DC 18v and 1.7 amps to power up. And if not, what would you recommend. Thanks again.
Great and informative video . Can you tell me if I have to use the current part of the buck if I want to use a 7.4 lipo reduce it down to 6v for an rc transmitter . The transmitter has 4 1.5 v AA batteries in it. And if I do what do you suggest I set it at . Your help is greatly appreciated 🙏

Hi, Yes it will charge. you just need to set maximum voltage and maximum current and charge. please see my channel on energy called WattHour youtube.com/@watthour
during the current limit setting, such at 14:29 , why the input power = 30.1V*0.1A = 3W, but the output power(almost a shorted circit) = 15V*1.6A = 24W, please help me to understand what happend....
oh suddenly I understand why: when outputing as a shorted circit, the output voltage dropped vastly 'cause the shorted circit has a very low resistance to hold a voltage, so the output power = * 1.6A =
Hello, what about the plated holes near the conectors? They are also connected to VIN and VOUT? Can I solder a pin there and solder this board to my own board?
Can this be used to "charge" a battery cell (1s1p) ? I have a PSU that outputs 30V 5A, and I want to output max 4.2V and max 1.7A (datasheet of 18650 cell says charge at 1.7A max). In other words, can this adapt constant current and constant voltage, or does this module just simply cuts the voltage (as seen in your video) if my load draws more than the set current limit? Basically, can this be used to push current safely into a battery cell at specific max current? Thanks for the review.
I wanted to use this for charging my Homemade 12.6V 16AH Li-Ion Battery which can charge at 1C. Now when I connect that to a 12V 10A Power Supply, it keeps triggering the Over Current Protection of the SMPS and thus the repeated trigger significantly reduces the charge time. Would this device provide a constant 5A current to the Battery Pack? At 1C, the battery can take upto 16A for charging but can this device limit it to only 5A?
can i use these to charge lithium ion batteries cuz charging lithium ion has 2 phases ccv I am confused about how to make a diy 48v 20amp charger (@1c) using a 1kw dc power supply.
you can but this will over only 3A to 5A. please watch this where I've explained the voltage and current of chargers th-cam.com/video/0mOqpCfAdy4/w-d-xo.html
Looking for the same info, when I connect my meter leads in the output, I can't seem to messure more than 0.6 amp, regardless of if I turn the current screw ?
Thanks again for your videos! What are your tools - like the screen on the left, some Windows software connected to RIGOL? Can you show your bench also and spend little time explaining about your tools?
You are welcome. Yes it is the software that is coming with Rigol Electronic load: www.rigolna.com/products/dc-power-loads/dl3000/ . sure I will try to make a video on my Studio-Lab in the future. I have added the link to the Thermal Camera and the electronic load in the description of video.
my friend, we are not worried about 6Ah or 200Ah. I have shown the voltage and current. it does not matter where you want to use it. for your 24V input see in the video if we can get 12V or 15V 1.5A. if so yes.
Thank you for your reply to my before question. Could you make a video about solder station controller project(if have with PID contoller more great) in nowadays. I want make a soldering Iron and controller with Arduino. I want make like JBC soldering station (I will buy Solder handle+Solder Pins others I will make) I sure so much hoobyst like this project also I want learn details from expert like you
I believe I mentioned it. Power LED and CC LED. When the current reaches to set value, the CC LED will turn ON. I don't remember the color, I have shown it in video.
you made me watch my video thinking I have not explained it. Indeed I have explained and given example. please watch without skipping and you will get your answer.

you can but this will over only 3A to 5A. please watch this where I've explained the voltage and current of chargers th-cam.com/video/0mOqpCfAdy4/w-d-xo.html
I could not get the output below 1 amp, even with the CC pot rotated counterclockwise until it clicks.
this is strange. you should be able to even set it to zero. I am not sure, it seems the components must have different value.
Thank you!!!!
You're welcome!
Can you please tell me how to adjust CC on this converter with only a multi meter without load and with load. Thank you
Looking for the same info, when I connect my meter leads in the output, I can't seem to messure more than 0.6 amp, regardless of if I turn the current screw ?
Thanks again for your videos!
What are your tools - like the screen on the left, some Windows software connected to RIGOL? Can you show your bench also and spend little time explaining about your tools?
You are welcome. Yes it is the software that is coming with Rigol Electronic load: www.rigolna.com/products/dc-power-loads/dl3000/ .
sure I will try to make a video on my Studio-Lab in the future.
I have added the link to the Thermal Camera and the electronic load in the description of video.
You could show real min input. Many
sellers declare 4V for the Red board and 5 and 6V for the blues. Guess aren't real XL4015?
Very well explained, how about xl4016
Please can u say how to set current in xl4015 using multimeter
I just checked the video and we have "How to limit the current". please watch.
Can i use this module to charge lead acid 12c battery or it is for use with lithium only?
Change anything
Hello can we connect Solar plate to the input of this board to charge battery from output ??
hello and yes you can. the output must be set lower than lowest voltage of the solar panel in order to get the expected voltage.
Module corner hole screw size please
Can we charge 12v 6Ah Lifepo4 battery with this module?
Input 24v 3amp adaptor and output like 14.5 with 1.5 Amp to charge battery
Is it work?
my friend, we are not worried about 6Ah or 200Ah. I have shown the voltage and current. it does not matter where you want to use it. for your 24V input see in the video if we can get 12V or 15V 1.5A. if so yes.
@@robojax thank you for your answer
Thank you for your reply to my before question.
Could you make a video about solder station controller project(if have with PID contoller more great) in nowadays.
I want make a soldering Iron and controller with Arduino. I want make like JBC soldering station (I will buy Solder handle+Solder Pins others I will make)
I sure so much hoobyst like this project also I want learn details from expert like you
Which way do you turn the potentiometer? I just got one of these and the voltage out isn't changing
Watch the video and do not escape I have explained it. You have to turn it 10 or 15 times .
if I set the voltage to 4.2 and limit current to 0.5A can i charge 18650 with this?
Yes you can.
Thank you for the great video. Can you please explain the functionality of the LED-s on this board? Thank you.
I believe I mentioned it. Power LED and CC LED. When the current reaches to set value, the CC LED will turn ON. I don't remember the color, I have shown it in video.
Maybe zoom out a bit so that we can see how you connect things..
I have explained all input and output. So the viewer don’t need to see anything unless the person skips the video and is lost .
Could u explain the leds indication
you made me watch my video thinking I have not explained it. Indeed I have explained and given example. please watch without skipping and you will get your answer.
so do you think it would actually be able to handle 5 amps?
I have tested and shown the maximum current
Hi sir, can i using this module to step down 12v 45Ah to 12v 2Ah? Iam really thankful for your advice
Hi, yea he battery capacity 1Ah or 10Ah does not matter 10Ah will last longer. It is the voltage
@@robojax thanks a lot sirr
Good review
Hi Zasa, I have seen your comment on my many videos. Thank you for that. Recently TH-cam made easy for creators to see who is subscribed 🔔 and who is not, and I was surprised 😮 to see you haven't subscribed🔔 to my channel.
Sir can we charge 12v 7.2 amps battery with this module please reply me
you can charge only if you can set the current limit. the battery gets damaged if you do not limit the current.
