Nice explanation. I'm going to use mine to connect a solid state relay to switch a mains charger on and off so it doesn't have to be on all the time. Its for a backup to a solar system. The relay connections you explained allowed me to see this was possible.
Thanks for a very comprehensive description of this unit. I measured that the unit is taking about 70mA from the battery when its not turning charge on. I would like to reduce this by turning off the display when everything has been set up. Do you know of any way either in software or hardware to do this ?
Sorry about my english I from Argentina, I have the same problem and I can`t solve this at the moment. My battery is 1.2 amp and this module discharges it quicly because the unit is taking 70mA
Only way I could see to do that would be to break the track connection that feeds the positive supply to the led display and solder jumper wires and add a switch to be able to switch it on or off but too be honest these little led displays use very little power the difference is going to be minimal.
Charger voltage is normally 14.4V, to reach 100% capacity. And 13.2V is the voltage of full battery, but in disconnected state. So the cutoff voltage should be something close to 14.4V and not just 13.2V. Please make tests and comment on that, so ppl can get their batteries charged properly.
Robojax , love your veo tutorials, they are very scientific, laboratory grade measures, very professional and productive, thanks for your excelent work y friend !!
Why is it that the charge time is right and wrong? If you have a lead acid battery the capacity is marked to 7v with a full charge cutoff being 14.6. But we tend to use the full capacity to make the calculation, but we don't use it all so it should be quicker. But..... When you charge, the current absorbed drops so you maybe charging at 2 amps by the end ...
Do they make reverse relays it would be nice to make it do the opposite to protect the batteries and shut off an inverter when the battery gets too low. Thanks
During the time of demonstration of charging a 12 volt lead acid battery as per the video, I wanted to know how the battery voltage is increased or decreased manually as per your video. The battery voltage by default remains constant. It can be decreased during discharging process while connecting a load. Also the battery voltage can be increased during charging but will take some time that depends on the charging current. But my main query is how the battery voltage can be increased or decreased manually as shown in your video during the time of demonstration of charging a 12 volt battery????
No. as you charge the battery, the Constant Current source you have will initially to keep the current constant, suppresses the voltage in order to keep the current constant. as the current decreases when the battery is charged, the voltage is increases. this is normal behaviour of a constant current source.
Hi your videos are great. Thanks for all this. My project I am using 3.2v 18ah battery. I need a similar circuit with lower cutoff at 2.0v and max at 3.6v. Can you recommend a module for this voltage range.
Mr. Ahmad shamshiri, please make a video explaining 3s bms board and tp4056 module explaining the benefits and uses in li-ion battery. Greetings to you from Saudi Arabia. Thanks
TP4056 is for 1S see datasheet here dlnmh9ip6v2uc.cloudfront.net/datasheets/Prototyping/TP4056.pdf See my other videos on chargers ru-vid.comsearch?query=charger
First of all thank you for such a nice video. Is it possible to use a common socket for both charging and use? Just like a wireless hand drill. How to make a circuit.
Hi. Tks for sharing this valuable info, about this product. What I wanted to know is if it would be possible to use battery power during the recharging period ((imagining that this could increase the reload time, of course)...
Hello, listen to the amps how are they managed? I need to charge a 12v 12A lithium battery pack. If I put a 1A charger on the battery does it get 1A? Thank you
Thank you very much for the good explanation . Please can you tell me whether I can use this to charge 100 amp battery. I use 100 amp battery for my home inverter. Thank you for your advice.
you are welcome. Yes you can charge. but maximum current as explained in the video, is 10A, more than that will kill this module. Check this better module that also measure the current up to 20A and it has tones of protections ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2DaC6oOV9oA.html
The spec sheet on Amazon said the Input to HW-632 needed to be 10-30V DC, so I used a Laptop Charger, 19.33V DC Output, for the Input to HW-632. My HW-632 did not turn on. Your diagram indicates a 220V Charger Input. Please describe your 'Charger Output' voltage. HW-632 website description says the Input needs to be 10V-30V DC.
Hello, it seems you have not watched the video and skipped. I just watched the video and at 1:22 I said very important fact. At 1:43 I mentioned the connection, shown the diagram and explained what it does. the 10V-30V DC will make it turn ON and work.
may be you did not watch it. I have provided subtitle in most languages. Activate the subtitle so you understand. you should have your own charger. this is just turning the connection OFF if the voltage comes to the batter is greater than the set value.
you did not mention what kind of 12V. I mention lead acid in the video please watch. 7Ah does not matter if it is 1Ah or 1000Ah. to charge for example your 7Ah batter at 1A. it means 1A/h (7Ah÷1A = 7A) and it will take 7 hours to fully charge or at 7A charge current it will take 1 hour (7Ah÷7A = 1h). if you have 100Ah batter at 1A current will take 100 hours to charge (100Ah÷1A = 100h). but if you charge it at 5A then 100Ah/50A=2 hours.
hi like the video I just wanted to know can you connect a load to the battery while it is in circuit and use it as a backup for a LED string light so when the AC power dies it will still run off the 12 Volt battery can one do this let me know if it's safe to do so. thank you.
how does is control chargig current? for example on motorcycle 6ah battery its needed to charge at max 1amps and on bigger car batteries at least 5amps so does it control current and recognize battery capacity?
Hello Mr. Ahmed! Thank you for the explainer video, it's really cool. Please help me in my inquiry, I need to protect the 48 volt 60 amp battery, where is it sold, and if there is any website on the internet that we can buy through it. Thank you very much all respect to you
Hello, Battery protection is not very simple. I forgot the maximum voltage for this module, but 60A does not matter when charging. it matters only if you are using it or discharging and you may need to protect it if you may draw very high current like 20A or so. But the rest depends on charge current and most devices with a simple relay can connect and disconnect 10 to 25A. here is one for 48V s.click.aliexpress.com/e/_9gIwp3 but there are many depending on how much you want to spend.
I have the same to charge a pack of 3 18650 batteries in series with 11,9 total volts and when it reaches de low voltage limit that i configured the relay start to turn on and off constantly and the voltimeter indicates peaks of 20 volts (voltage input from solar pannel) in the output to the battery. When apparently it stabilizes and the led is turned on it dont charging anything, the voltage drop on battery continues. The entrance line from solar pannel down from 20v to 11,42v when it s happens. Same result connecting dedicated 15 - 20v computer charger. ¿Low amps, my fault or module fault?
This is just a switch to protect your laptop if voltage goes higher than the value you set. So use your charge or lower source and this module protects your load which is your laptop.
Hi Friend, I am trickle charging my car battery through Dewalt 20V using LM2596 and it's working really good and have been using it for about an year from now. Now my question is I want to protect my Dewalt Battery from going too low on Voltage and I tried using XH-M609 and LM2596 together but it didn't work. Now what do you suggest me to buy which might help. I appreciate any help please.
Hi, if you have a power module that has constant current, then you just set the voltage at maximum allowed voltage and set the current at charge current. For low voltage protection this module can be very helpful or this (we commenting at) module that can monitor the current as well ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2DaC6oOV9oA.html
I used this as my car charging module. The lower charge set to 3v as my battery become dropped 5v once. And set the maximum volt to cut off as 13.2v. but when I connected the drained battery, the led light won't turn on for charging state. And it won't start charge. I checked the power supply. It was 16V at that time. Could you please tell what is wrong with the settings here?
I set the module to turn on led in the module while connected to drained battery now. But the led doesn't turn off when reached its maximum volt which I given for turn off. Hope your response as sooner possible.
Useless unless it controls current as well! It also needs battery to be fully discharged before it can be recharged. A XL4015 module seems a much better choice as controls voltage and current.
yes. that's why I gave warning. But for those with specific current power supply, this might be useful. I don't like it. Tht's why I did not put the lithium in the title too.
If its a 12v lead acid battery that anyone is using this on the lower setting should be minimum 12.2v as going less than 50% discharge on a lead acid battery reduces their life considerably.
no. lead acid battery can go very low and it will not get damaged. But keep the lower value to 10.5V to 11V. it depends on what is this battery suppling power to.
Please watch . This is just turning on and off. You need your own charger. Use this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fUYt0dQnkZc.html or ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-I_rRTJgONTw.html
Hi Robojax...how do you get the XH-M603 to detect and charge a battery below 5v DC? i have a 12v 7Ah UPS battery connected to the XH-M603 but it cannot detect the battery and charge even if i set the lower limit below 5vdc. I have the upper limit set to 13.7vdc. Please help me.
Hi, I don’t remember the minimum voltage but you set the main and maxim and it should keep your battery charging. Pay attention to what I said at the beginning. Watch carefully otherwise your battery can get damaged
@@robojax thanks for the quick reply Ahmad...once i set the lower (11.7vdc) and the upper limit (12.7vdc) even if the battery voltage is below the lower limit it will right away charge the battery and will stop charging at 12.vdc? thanks again.
Read or open the battery to see what the voltage is. then get a converter that has constant current mode or CC so you can set current limit. I have so many of those see my videos ru-vid.comvideos and I have explained how to charge a battery
so you will use this XH-M603 as a switch. Watch this video to learn how a relay works ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-N-xbxtGGoHw.html and use XH-M603 to control a relay that is capable to turn ON/OFF 100A like this relay amzn.to/3wFAHtB
Hi, no because car battery needs to be connected continuously. this will disconnect the battery. also car will need regularly 30 to 50A and when starts it used about 100A to 400A. this can not handle more than 10A.
@@robojax No, Sorry my bad the question wasn't clear, I put it differently now, I have a portable Bank charger and that's connected to the car battery in the car for float charging and the charging is in progress, the charging voltage is 12.6 and now we go inside the car and acidentally start the car and the car Alternator is gonna kick in and push in 14.5 volts and huge amounts of Amps to the portable bank charger ( external charger) so the charging bank is not gonna be damaged from14.5 volts and lots of Ampere from the alternator or my external charging bank is protected by diodes?
@@robojax This unit will not Limit the amount of amps. Using this When you're alternator raises the voltage You may find that your battery is charging too fast.
Hi, nice to greet you, I liked your video, but I have a question, could you clarify it for me? I have a transformer that in vacuum I measure 17 volts RMS but after I rectify it and filter it goes up to 24 approximately and that is correct because the capacitor that I am using is charged to the peak volt, now when I connect two lamps of 12v / 130w each One, the voltage drops to approximately 13.6v, the current that I measured consumption of these two lamps is 15.7 amps, could you then use this voltage source to inject it to the xh-m603 / 12-24v module,? the battery I intend to charge is 12v / 70A lead acid .. thanks mr,
Hi, I read this and did not get it before, but today I had reply as your comment was waiting in my mail box under "I haven't responded". I did not get "could you then use this voltage source to inject it to the xh-m603 / 12-24v module,?"
Salaam Ahmed. I am currently setting up a XH M603 with a 16vac transformer , which has a bridge rectifier connected to achieve my DC power. My output after capacitor of the bridge rectifier is 24V. Currently the M603 is in standby mode attached to a 12v 9ah sealed lead acid battery. When the battery dropped to 12,5V the relay engaged on the switch over to 12,4V but then it rapidly rose to 12,8V and deactivated within seconds. What could be the cause here since my switch-off is at 13.4V. Do you have any advice please.
Im looking to buy this Brand CPTDCL charger cut off board. Can you help me out. I have a portable solar set up and direct from alternator charging my secondary battery. Can I reverse the wires to the CPTDCL charger that go from the charger input, to the charging output to battery wires so instead of charging the battery, I want to rig it to operate a 12v motor and be able to start n shut it off.?
Thanks for your review. I snagged one of these from a reseller for 50 cents, and frankly I'm still trying to figure out what I'll use it for. I suppose I could simply attach a basic wall-wart DC power source to the input and turn it into another Lead Acid charger, but somehow I think I have better I could do with it.
Later in your video, you indicated that your Charger Input was 12.8V. Is that correct? So in Canada it's 220V Wall Outlet to the charger that was putting out 12.8 Volts. Is that correct? My unit didn't work at all. Input to HW-632 was 19.33V from a Laptop Charger. When I connected to an 18AH Battery, I didn't get any reading on the meter whatsoever. Any thoughts?
to learn about current, please see this video at 6:22 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3C33DpcSwIw.html I spend time, searched for the video, played it and got the time for you.
I've added link to resources page for this product in the description of the video. here is the link for you robojax.com/learn/arduino/?vid=robojax_XH-M603_charger
Can you tell what rating for a charger I would need to power my XH-m603 module, I want to charge cordless drill batteries which I believe are 18650 batteries?
This is NOT charger. I have explained it and also pot that in that title . This is chafer controller . This is just a switch to turn on or off a charger
your question made me watch the video and I found the answer. I even showed a diagram. I spent so much time making this video. so please watch it without skipping. I answer any question that is not answered in the video.
@@robojax Sorry I'm not experienced enough. You said "charger or solar panel". I don't know if a solar panel is similar to a power supply. I've seen in other videos using an ATX PC, so my question is : can I safely use the 12 volts of a standard ATX PC input power supply?
Hi, I mentioned that this is just turning ON and OFF. it can't control the current. so if your solar panel 's current is below the maximum amount of current that your battery can handle, then connect it directly. but if your solar panel can supply very high current that might damage your battery, then you need to put a charger or constant current device so limit the current.
i have a question. if the charging voltage is higher than the stop value will the controller then still be able to see when the battery have reached the stop value.
@@robojax but after trying it, it seems that it turns off the charhing because the charhing voltage is bigger than the stop voltage. Causing IT to think that the battery voltage is bigger than the stop voltage
Isn’t that good if the charging voltage is greater then the stop voltage it should stop it? You voltage greater so it should stop it and this is how it is made . So it is working perfectly.
