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

@stinkycheese804 Ай бұрын

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.

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.

Oh and as PS: you have 2 video's of the 3S charger boards (very good) but of course I bought the 4S 40A version. One problem that 75% of the buyers have (me too) is that the module does not output 16 Volt when you hook up the 4 18650 batteries, it gives out 12 Volt and that doesnt change. Also some mosfets dont have a voltage on the gate.. . But the solution is very simpel: most people hook up new and fully charged batteries. The board will go in protection mode and then the board's mosfets start working only if you connect it to a charger (CC and CV of course) for about a minute. After that the board works as it should. Took me a whole day to figure out, so if you eventually do a review of the 4S boards, remember to mention it :-) Have a great day!

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.

What is the minimum current that the module can output at 5V?.Thanks.

@robojax 4 жыл бұрын

for power modules it is always the maximum that maters. Minimum has no meaning. Only quiescent current when there is no load matters for some application where the system is powered with small battery. You can get that from the datasheet. the link to the datasheet should be in the description.

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 ?

Hello can we connect Solar plate to the input of this board to charge battery from output ??

@robojax 3 жыл бұрын

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.

Can i lower the input current? from 5A to 2A ?

@robojax 2 ай бұрын

the output is important of 2A. if showed that this module can output 2A , then yes.

Hello can i use this for my DIY wind turbine generator?

@romychajla880 Жыл бұрын

what ripple will this tolerate? can you feed it rectified ac?

@robojax Жыл бұрын

No. you need to have proper filter and large capacitors connected to the output of rectifier. this needs good DC voltage.

Bro help me please I have. 48amps of lituim ion of 12.6v battery pack i set the step down at 12.6v but when it reaches at 12v it stops charging and the blue light is on why i do not understand And i use the 16v 2.5a charger

@robojax 3 жыл бұрын

You must set the voltage at 12.6

Is this good for limiting the current going through a robotic arm with a 4-6V servo motor (20kg)?

@robojax 3 жыл бұрын

You can set current limit but you have to know and every time you wanted to change it, you have to set it. Yes it will work

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?

@jeffbluejets2626 10 ай бұрын

schematic of connections would be a good move.

@robojax 10 ай бұрын

just check the datasheet of XL4015. I have shown it. that is the schematic.
