    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.

    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.

  • @RoyAndrews82
    @RoyAndrews82 Před 3 lety +3

    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

    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.

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?

      @@robojax Yes your current videos are really great, and I like that you make a review. I also buy based on your videos. But a separate video for improving or modifying them is also very good content. If you are capable of making those contents, that would be really great. You have the tools to do those and measure. Hopefully you could continue to make great reviews and also add a separate video on how to modify or improve those products. Like increasing power (adding heat sink, replacing parts with higher capacity, changing coils with thicker width, etc).

    • @robojax
      @robojax  Před 4 lety

      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.

    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.

      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!

      Hi, output can never be greater than input. I've shown the efficiency which show 10 to 20% amount of energy is lost as heat. so Pin=12V(3.34)=40.08W and if you subtract 15%=6W, then output would be 40-6=34W. at 14.4V then I=P÷V=34÷14.4=2.36A is the output.
