Wow,excellent Mr. Electron
ЭТО есть ДУРНЯ ! Для туземцев .
Todo bien gracias lo felicito.
Ok felicitari
I just want to know the cap uf
Quero colocar na bicicleta motor esteira que tenho
Obrigado
Deixa foto pra mim ver passo passo
It's oke
PAR QUE CONECTAR EN PARALELO LO CAPACITORES ELECTORLITICOS *PERO A TRAVEZ DE 2 BOBINAS CON NUCLEOS D EFERRITE?* SE LEYO QUE ES UN FILTRO,OK,PERO JAMAS VI ARMAR UNA FUENTE O CARGADOR DE CC,CON FILTROS CON BOBINAS CON FERRITE. *ES POCO HABITUAL*
Please share the circuit diagram

man, I love those scissors. great video also. :)
this module can charge seal lead asid bttry?. this module has overcharge bttry protection?. the input can connect to solar panel to charge SLA battery?. what min and Max (volt n amp) battery it can charge?
Great video. I learned a lot. One thing I'm curious about is what would happened if you try to charge the battery with the battery itself with the buck converter.
can i charge my 1.2V NiMH battery with this?
Thank you soo much for rich content video, it answered a lot of question I heard about the about the cell's behaviour on CC-CV charging. Ndiyabonga kakhulu
Hello where to get discharged battery
Thanks for interesting video. Where you show current level dropping when set voltage (4.2v) is reached, what triggers current drop. Is this a feature of all buck convertors or do I need to purchase one specifically for charging Li-ion?
Hey at 24:05 what is that device with relay
17:07 "The current is really high" - it's because an ammeter resistance is near zero, so without a load in the output you made a short circuit
Does the unit stay set with different inputs? Say I have 2 different power sources, 12v and another 14v. Do I need to set the output for each unit or is the output not related to the input?
I tied spinning the Voltage pot like forever, and still can't get the output voltage over 3V (with 17.8V input). What am I doing wrong?
I would have liked to see the current draw on that 8 amp hour pouch cell when the charge cycle was complete. Someone pointed out that the 18650 you used had a built in protection circuit that was actually responsible for the zero current draw.
May I please ask about 5v input - will it work? (eg. USB port Vin, Vout 1.4v charging NiCd battery)
Fabulous Presentation :-)
Hey! Richard, your video is awesome, please tell me one thing, could I use this module to charge 12 volts 32AH battery with 3-4 Amps of current, ?
During hazy days a solar panel can show say 20v but will produce little or no current. When one drops down to lower voltage due to being in shade it will produce no real current.
Thank you very much sir.
With full sun my solar panel was able to put 500ma into the battery pack which is a LiFePo4 set arranged in 4P. I set the output voltage to 3.60 and the current to max. When a heavy cloud came along the out volts would drop to that of the battery and amps to 0.0. I plan on putting a boost converter on the battery pack to boost to 6V. This is to drive a game camera. So, Buck from solar panel and Boost to camera. Wish there was a way to cutoff the Boost when the batteries drop to 2.8 volt.
Make a video of using a buck converter to charge a LiFePo4 cell with a 5-10W solar panel. Or, to maintain a fully charged cell. What do these buck converters do when input voltage drops below desired output voltage? (Just tested with some cloud cover. The voltage on the output pins does not climb above that of the battery. Amps is showing 0.0. ). Hopefully I can get some full sun today)
If using multiple of these charging several cells 1 per cell but the cells are connected in series won’t it be a problem are the grounds isolated in these units?
I made a Lab power Supply with those 2 modules: XL4015 + LCD Voltmeter 4 digits ( the good model, cause 3 digits is not the best) When I turn potentiometer to set voltage on XL4015, there is a some delay before the actual voltage is displayed on the LCD. I tried XL4015 + Ordinary Multimeter, this delay is not present, the voltage is displayed live while turning the pot. But as said XL4015 + LCD voltmeter Display combo, there is some delay, like the voltmeter is analysing the new voltage value. I would like it to be instentanatly, no delay, while I turn the pot, the voltage is display directly, without this delay. Maybe somebody encounter this, and got some idea Thx
Can you please tell me how to adjust CC on this converter with only a multi meter without load and with load. Thank you
Thank sir best tutorial for this module Only a question. can i short output without load for set current or need a little load? Thanks
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
Can i give higher than 5a as input?
Excellent video Ahmed Keep it up ( i have a same question as asked Feroz please reply ) 1 Input Adaptor Volt 12 and 4.16 Amps as per your calculations it is 42.5 watts 2. required output is volt 14.4 and 4 amps as per your calculations it is 2.95 amps it is still low as per my needs 14.4V / 4A My Questions 1. So i need a 12v and 6amp adaptor for take 14.4v and 4.25 amps from buck converter ? 2. still i am good if i am taking out with my old adaptor 12v 4.16A from buck converter 14.4v and 2.9A ? that ok/possible take higher voltage from buck converter by multiplying input adaptors volts and amps like input buck 12v 6a out from buck 14.4v 4.25a ? Thank you in Advance
potentiometers do not work and when I want to charge the battery the green and blue lights are on respectively
Ahmed that is awesome excellent i have a question : i have this buck converter xl4015 5A Example: i have input 12 volt and input amp 3.34 it is 65w adaptor smps , i want out is 14.4 volt and 4 amps = 55 watts ( is that possible ) Thank you
Excellent video! You explained in detail and covered nearly everything I'm now sub'd
Wow the most comprehensive XL4015 review I've seen. Also I guess I really need to put a heatsink.
Dramatically fantastic. Thanks
why they lie in china for the product s? i order 1 i got it , i look at the 2 capacitors is 36 volts , and in the description they say the input voltage is from1.25 to 36 volts , and the output is not 5 amps , thank you for your video ,
I could not get the output below 1 amp, even with the CC pot rotated counterclockwise until it clicks.
I see Ahmad I click like. Quality content!
why he did not tested for 5Amp load?
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
Best thing on internet for this module.
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.
Hello can we connect Solar plate to the input of this board to charge battery from output
Could u explain the leds indication
Good
I am sorry. I don't know your Hindu . Please speak an English. THANK YOU.
Very good project. Plz make a powerful mini inverter .
Nice
Muje tv aur freez aur pankha aur bulb chalana hai to kese chalaye
Beautiful Projects
Sir aapne video ki title galt daali hai 220 volt to 12 volt converter hogi not 12 volt thi 220 volt converter
Bhai Assalam Alaikum Mujhe 12 volt charger se 220 bijali nikalna hai vah kaise karna hai
Sir please make induction soldering iron
