How to use XY-DJ Battery Charge Control Module with Over Charge Protection Solar - Robojax

[@ericus030878ify]

Well explained👋 Your channel is my go to section on KZbin whenever I need to check reviews on such modules. But I just have one question on this XY-DJ. Can I connect a solar panel on the NC and an AC charger on NO of the relay? I did this on my YX-850 ups module. It worked for a month but eventually burned the relay. The current was only 5A, both from solar panel and AC charger. I was thinking of automatically charging my battery via AC charger if power from solar panel is not available. Thanks in advanced 😊

Hi, thanks for explainig the OP time (999 minutes) cant find this important information .So now if my Lifepo reaches 14,4 V the Beercooler will be on for 2 hours and the free Energy will not be wastet by heat via Solarcharger.regards from Deutschland

[@TechnoEveryday]

2:40 if i set charging voltage 14.6V BUT cut off at 14.4V, will it harm the battery?

[@robojax]

each product is different. check the datasheet from the manufacturer.

[@TechnoEveryday]

I am talking general. Can we charge at higher voltage (say 14.6V) and cut off (at 14.4V as per specs), is it safe or better to charge fast?

[@MrWriggs]

Brilliant Tutorial, I struggled to follow the Ali Express I structions and diagrams, but using this video, I was sorted instantly. I am using it to terminate the charge of RC 4 and 5 cell Nihm packs, so 7 volt upper with 6.8 volt lower is working superbly. Thankyou

[@ThanosFrl]

yes thats very good video

[@mustindraw]

I bought this module a few years ago, but I can't use it and don't understand how to set it up. Thanks for your education.

[@robojax]

Glad to help

[@iloveaviation-burgerclub-a8145]

Thanks buddy. I like to ask if one can conne t abattery to the input nd simultaniously to the V- /V- to operate the module with the surveilled battery. The relay would then be used to cut off the main load which the battery is used for. I like to install this in a amplifer kinda street music gear. Thanks in dvance. Hope you got my idea.

[@igorfomenko9189]

this board has very low voltage accuracy (-0.3V in my discharging case) and there is no calibration function

[@miguelbarrero777]

This module have one fault in Mode U-2, when detect for first time low limit voltage start to charge, if reach high limit voltage stop to charge, and will start to charge again when detect low limit voltage, but if time is reached before than high limit voltage, then stop to charge, but never start again to charge when detect low limit voltage, you need to power OFF and ON the module, or reconfigure again Mode U-2 to reset the module, or dont start to charge never more in mode U-2. And is possible that have the same error in all modes that use timer.

[@Naushadkhan78623]

My unit show -2v of the battery voltage like if my battery volt is 13.5 it will show 13.3v, is there any solution to calibrate it

[@walterrldias]

EXCELLENT VIDEO!! thank you so much... I am trying to find a tutorial for the XY-CD60L, it has only VIN and OUT ports. Can you help?? I want to know if I can connect the solar panel on the Vin and the batteries and the load in parallel on the OUT Port. Or at the very list a charge/discharge control board on the OUT port and then the batteries and load separately connected to this second board (which has separate OUT and BAT ports). I have liked and subscribed. Thanks a lot.

[@robojax]

Hi, just did a search and found it on AliExpress here s.click.aliexpress.com/e/_DF8FsDz and wiring for load and battery is shown here. ae01.alicdn.com/kf/H8a894d94896b4dc6b86889f85726766bS.jpg keep in mind that your battery must be the same voltage as the load. this module does not change the voltage or current.

[@walterrldias]

@@robojax thank you so much for taking a look at this! unfortunately, what I need is to connect the solar panel to VIN and the Charging Module to the OUT port, I would connect the batteries and my cell phone to the charging module. you think its going to work? Solar Module to the Control board, control board to the charging board, charging board to batteries and load on separate channels.

I will go on trying to get success with this. Johannes

[@royalsingh]

Nice review as always. Thanks for it. Just that @ 25:20 you mentioned it not functioning good with Lithium batteries. What does Type of batteries has to do with functionality of this generic module? Its governed by Input voltage and as long as it gets the reading it should work. Could you please explain the issue in a bit more detail. Thanks

[@Nordicvistas]

i baught one off this to monitor my lifepo4 battery if it works i will bay 36 more to my Car insted of BMS and by a sepret Balancer insted still waiting for it to come in the mail may volt is 3.3 nominal and 3.65 at top so this moduel is not best still loking for a more prices model

[@robojax]

You are welcome. Yes you are right it should work. I mentioned it because people don't know about Stat Of Charge (SOC) or a battery and other parameters. If you know all parameters of the battery, then you can use it and it is not automatic. Lithium batteries need different current at different stage of charge. So if you can handle that, use this otherwise this will reduce the life of battery.

[@AztecWarrior69_69]

Actually this Module is Not a charger at all. All it does is read the voltage and Connects the charger to the battery. It doesn't control how the battery is being charged. There are two main types of chargers. PWM and MPPT. MPPT are used for deep cycle, lithium and a few others. PWM are basically for car battery types. I won't go into why and how they work. There are several videos and sites that explain all that. All this module does, is connect those types to the battery as I said before. The MPPT chargers already come with overcharge protection (discharge protection not so much), so if you want to use it for that then that's an option but the actual proper charging is handled by the MPPT.

[@philhen2215]

Hi. Good vidéo, only i think that your measure voltage is voltage charger when is connected of battery.

[@salsepulveda494]

Success - everything works - thanks for your help. The charger automatically shuts off when it gets there. I'm charging the battery. Thanks again. I'm glad I didn't just throw it away.

Good day sir. I would like to use this module in my diy solar setup. My novice question is how do I connect it to my solar charger controller and battery. Which wires are going to the input side? Hope you can help. Thanks

[@herohito937]

Peace be upon you Please, I have a question about the battery protection circuit. Xy-dj made a movie about her Question Do you protect the battery from overcharging at the same time from overloading i.e. do you use it either to protect from charging or to protect against unloading Or both. In same time Please if you can drew the wiring way connect in this case

[@manuelr7121]

this is awsome my only question is how long does it last??? life expectancy ? of the module does it break easily?

[@salsepulveda494]

Why are you NOT answering the questions? On the LEFT SIDE, is that only DC in? What is it - AC or DC in? On the RIGHT SIDE, if I'm using an AC Adapter (Description: Input 100-240V - 1.5A, Output 19V - 2.64/3.42/3.16/3.68A), is an Input on the LEFT SIDE still required or does the AC Adapter on the RIGHT SIDE become the Input? Please answer these questions for me?

[@robojax]

LOL. I am setting by the computer to reply. Sometime I check them every two days and some times daily.

[@salsepulveda494]

OK - I have 19V going in and Alligator Clips on the battery side. Nothing is connected to the three screws on the Relay Area. I set the parameters for U-2 as follows - Lower Limit 12.8V, Upper Limit 14.4V and to run for 20 minutes. The Battery Voltage is 12.77, so I expected the XY-DJ to begin charging to 14.4V, however, it only shows 12.5V and hasn't changed from that for the last 10 minutes. What's wrong? Can you help with that?

[@robojax]

instead of the battery connect a bulb. see if it turns it ON. unless the wiring is incorrect, or power supply is bad. if you set the limit to 14.4, and battery voltage is lower than that, it should charge.

[@jm-ev5bb]

Thanks! I bought a few of these not knowing what they did and finally found a good tutorial. Well made video, I subscribed :-) now in mode 1, could the input charging power be a solar panel to replace the AC in?

[@robojax]

You are welcome. Sorry I did not understand your question "input charging power" . I watch ed the video to answer your question but could not. Perhaps you are referring to Mode 1 and Mode 1 . Please watch it gain.

[@RF-yz5po]

Yes it can be because the relais switch contacts seem to be isolated and can switch AC loads.

[@ShahrukhKhan-il1pw]

I am having a charger whose output is 24V- 30A (900W), which is used for lead acid battery. So, can you please suggest me the relevant auto cut-off device or circuit for the same?

Good, you very nice and very kind, i like your clip. I am vietnammise so from viet nam. Thank you very much

[@robojax]

You are welcome. I welcome all Vietnamese .

[@salsepulveda494]

If I use an AC Adapter (Output 19V---2.64/3.43/3.16/3.68A) is a Left Side Input 6V-40V still required? And is that Left Side Input (6V-40V) AC or DC? I'm assuming the Output (0-60V) is DC because it's obviously going to the battery. Is it Input on the left (AC or DC?) or AC Charger Input on the top right? Is it a choice, one or the other, AC Charger Input or Input on the Left?

[@robojax]

you made me watch the video. I have clearly a section called "wiring explained" and the link is in the description of the video so you can jump directly. I have answered your question in the video. I've spend about 2 days to make this video. if you own the module, 26 minutes is nothing to watch. good luck.. Please check the link to the resource page for this video or click here robojax.com/L/?id=260 and I just added extra information concerning your question. But it is clearly explained in the video.

[@salsepulveda494]

So......the if I connect to the Battery with a length of wire and Battery Clips, I can run the wire to the LEFT SIDE INPUT of the XY-DJ Module to power it up while also charging it. So that means I can use my Laptop Battery Charger on the Right Side of the module instead of the Left Side. Is that correct?

[@robojax]

Yes. correct. Stay safe. Ahmad from Canada

[@philhen2215]

Hi, Pensez vous que ce type de carte permet de suivre la charge d une batterie.. Car la mesure effectuée correspond je pense à la mesure de la tension du chargeur quand celui ci est branché sur la batterie car je ne comprends pas comment il peut mesurer uniquement la tension batterie avec un chargeur qui fournit une tension supérieure à la tension batterie pendant la charge. Avez vous une réponse.

[@robojax]

Hello, lorsque vous connectez une tension plus élevée pour charger par exemple 13,8 V, si la batterie est vide, la tension sera de l'ordre de 11,8 V à la borne de la batterie, cela est dû aux caractéristiques du chargeur. Lorsque la batterie est vide, elle a besoin d'un courant très élevé et le chargeur contrôlera le courant en réduisant la tension. Essaye-le. tu verras.

[@uniqueautomationelectronic5696]

[@rasakibola1116]

Great video as usual. Please can one connect a solar panel directly to the input of this module to charge a battery?

[@salsepulveda494]

Can a Jumper wire be placed right into the Positive Battery Terminal then leading into the Terminal just above it? This idea rather than placing a wire in the middle of the Positive Battery Wire going to the Battery. This will achieve the same result. Isn't that correct? Let me know. Thanks.

[@robojax]

Please see my reply to your other comments.

[@salsepulveda494]

If I remove the Battery, Output Voltage is 00.0. When I connect Battery, it back feeds to the Output Terminals of XY-DJ and reads 12.77V.

[@robojax]

Sorry, yes when you disconnect the battery, it can't do anything. snipboard.io/AHhRpV.jpg then your setting is incorrect.

[@salsepulveda494]

Again - On the Right Side, can the Negative from the Wall Charger be place directly into the Negative Battery Terminal of the XY-DJ Module? The diagram shows it in the middle of the Battery Negative Wire. Does it make any difference?

[@robojax]

Please see my reply to your other comments.

[@mrbravosworkshop]

Hello, I think that this module is thought to work on Acid Lead batteries. because 57.6V for 48V batteries is too high. The right voltage for 48V batteries is 54.6V Also, do you have the manual to control the Module via Serial port?

[@robojax]

I just watched the video to answer your question. at 7:15 I have answered your question.

[@salsepulveda494]

I'm in the U.S.A. All your wires on the right side are Black, and that's confusing for learning purposes. In addition, the connection of the Light Bulb as it relates to a Battery is totally not in view. We really can't see anything when you are making this connection. The Battery is not in view either. I have a Laptop Battery Charger plugged into the wall that changes 120V to 19V, and that is connected to the LEFT SIDE INPUT of the XY-DJ. So 19V is supplied to the LEFT SIDE of the XY-DJ. With that in mind, on the RIGHT SIDE, the diagram suggests that a separate Charger needs to be plugged into the wall (120V) as well. In this case, a light bulb, and the positive wire needs to be cut and placed into the COM PORT (the center screw) of the Relay. Then the positive exits the Relay from the Lower Screw Terminal and is connected to the Battery Positive Terminal Wire, and that finally connects to the Battery Positive. Battery Negative on the XY-DJ just connects directly to Battery Negative on the Battery. Is all this correct? Please let me know. At present, I have never connected to the Relay Ports.

[@robojax]

I just watched the video. It can't be explained better than this. I have explained it with diagram and showing the wring and explained it. it can be connected 2 ways so I explained both. .have you checked the resources page for this module? snipboard.io/AHhRpV.jpg

[@salsepulveda494]

@@robojax I connected a light bulb on the Battery Output Terminals. I get nothing. Also, the meter reads 00.00 Volts. When my Battery was connected, the meter was reading the same voltage as my Battery - 12.77V. I guess it was back feeding the Battery Voltage onto the XY-DJ Meter. On the LEFT SIDE, I have 19.3V on Input. Without any outside wire connection to the Relay, is it connected to Battery Output on PCB? If so, the Relay may be causing 00.00V on the meter and no output whatsoever. Is that a possibility. Again, do I need two items plugged into a wall outlet to make this Charger/Discharger work? One for Input Power and another for the Charger on the Right Side? Let me know. Thanks.

[@wertz535]

Thanks for the very detailed video! 👍👍👍👍👍 Ask: Are the set values retained when the circuit board is switched off?

[@robojax]

Yes

[@salsepulveda494]

On the left side, is that DC Input and the right side is DC Output? Is that correct? Also, when this unit is totally disconnected, does it revert back to the factory setting? Or are the previous settings still in effect when you reconnect again?

Does this have that low a setting didn't see the setting for cutoff discharger voltage set to 3vdc?

[@robojax]

Thanks. this module doesn't know anything about discharge. But it can watch the voltage. Lithium battery has state of charge and when voltage goes below 3.2 or something like that, is considered discharged but it varies by the manufacturer of the battery. so Yes. this can work if you set proper voltage. But remember this can't control the current and that is very important. otherwise you battery will get damaged.

On a PCB there is the risk of tracking, particularly if the surface is contaminated and/or is in the presence of high humidity which is why the better type of switched-mode AC/DC power supplies feature a slot in the PCB between the primary and secondary sections of the circuit. Big Clive is at pains to warn us of insufficient separation, either on the PCB or in their transformer windings, in his video strip-downs of dodgy USB plug-in adapters. In any case thanks for a useful lesson in the use of the module, I've had one for some time and was in the dark as to its features.

[@robojax]

I agree with you. Thanks.

[@deliniaduyun9958]

Can i apply this module at my solar project to charge my battery?

[@robojax]

yes. you can. I will change the title and add the word solar so people know.

[@vintagethings6548]

Hi, my congratulations on your videos, which are very complete. I have the following doubt, is it possible for this equipment to work in two modes? that is, to have the charge and the discharge (eg U2 and U4) defined ? Using an Arduino connection for example. Did I understand that there can only be one defined mode? Thanks

[@robojax]

Hi, thanks. yes you can turn ON or use only ONE mode.

[@TechnoEveryday]

If you really want to hookup Arduino, then write your own code and no need to waste double money

Helo , I need a help from you can you pls make video for electric scooter i have 2 lithium battery 1 is 60v 24ah and othr is 72v 24ah for this i need 60-80v auto changeover or auto cutoff circuit

[@robojax]

Hi, I have no experience with electric scooter. I will see if it worth working as it seems very expensive.

[@sumannaidu9199]

Pls make it , i m searching but not found for dual battery auto changeover charging for 60-80v . It will helpful for every one in feature .

Excellent guide and explanation.

What is the actual voltage (measured) precision of this module?

[@robojax]

Unless I have to watch it to tell you but, I showed that I measures and responds to 10mV of actual voltage.

[@emuland]

There s a way to read @ precisione of 0.01v from serial?(even if lcd show max 0.1v)

[@robojax]

no way. her is the page of one seller www.aliexpress.com/item/4000068468499.html and it show ± 0.1V.

[@simonmasters3295]

I have one reading 64v on what two other instruments read 55.5v Honest Don't know what's going on Left it running for last 20 mins Fingers crossed So far disappointed But great little package I'm wondering if some XY-DJ packages have 12v Songle Relays and therefore 12v supply, I'm chucking a good 9v at the power supply, isolated entirely from the sensed circuit, and it's clearly reading high!

Hello can ı charge 8s li ion battery pack ı need 33.6v thank you

[@robojax]

Hello, it seems you have not watched the video. I have explained everything you need to know about this module and how to charge.

[@BoraGurses]

Robojax yeah ı didnt see any 18650 in video instead of writing this you can say yer or no easily right?

[@Merajs28]

Can this device also applied for the cellphone battery

[@robojax]

this doesn't know the type of battery. It just knows the voltage. So if you set proper voltage it will work lese, it will damage the battery.

[@philipfrancismercurio9854]

Would it be possible for cellphone charging?

[@robojax]

this is not suitable for Lithium batteries as those batteries, need current control and voltage control. This can control only voltage and might damage the battery if you don't monitor it yourself.

[@IpunkP]

this what I need, thanks 👍👍

Hola , estuve mirando tu video , me da gracia de ver hasta que punto no saben como facturar estos chinos , fabrican de todo lo que se les ocurre aunque luego termina siendo una parte del todo , bueno, las tensiones son mas o menos esas , en el caso del litio si exceden de 4,1 volts se puede formar oxido en el terminal de cobre , y por supuesto por debajo de 3,6 volts estan débiles claro que no hay un control de la corriente y en las de litio es muy importante ya que son muy explosivas e inflamables no sera la primera vez que alguien sufre quemaduras , una bateria de litio 18650 se puede cargar con dos amperes pero con un gran riesgo de elevación de la temperatura y de explosión , algunas tienen protección interna con un circuito electrónico pero no conviene una corriente de 2 amperes , yo prefiero no superar los o,8 amperes o menos ,a estas baterias hay que respetarlas por que te responden agresivamente , ahora con las de gel , la cosa cambia ,claro que tiene que existir una diferencia de potencial al final de la carga , en este caso 14,6 volts , de lo contrario ya no se cargan , aunque al final de la carga la corriente disminuye drásticamente , y se hace mas lenta para completarla , , las de niquel cadmio tienen memoria , por lo tanto hay que descargarlas , estas ya no existen , las de niquel metal no tienen memoria , y en general las demás , en conclusión este dispositivo es un voltimetro , un comparador programable con histeresis , y un rele controlado como llave de arranque y parada , en fin un aparatejo mas de la ingenieria china al servicio de sus bolsillos , jajajaja, buena explicación , aunque hay que tener una idea para usarlo correctamente , un saludo !!!!!

[@robojax]

Hola, la carga siempre es un proceso complicado. Ahora hay miles de universidades de todo el mundo trabajando en cargadores. En unos pocos años tendremos nuevos dispositivos para trabajar con dispositivos Fuel Cell y el hidrógeno parece muy prometedor para el futuro. El juego de chepeaset y el más abandace del universo. Pero en cualquier caso, tendremos que almacenar energía desde la toma de corriente doméstica o desde la pila de combustible de hidrógeno. Gracias por tu repetición. Tenga un buen día.

[@vicentematricardi3596]

@@robojax Hola , cierto , estoy al tanto de algunas cosas , estaria bueno un desarrollo serio y transparente del uso del hidrógeno , como fuente de energia no es nuevo , el sol y los océanos son realmente inmensos, pero con la carrera enfermiza que aun tiene el petroleo quizá tengamos que esperar , con relación al hidrógeno aún se tejen mitos sobre el destino que tuvo Stanley Meyer , aunque quizá sean solo especulaciones , Saludos !!!!!

[@robojax]

Hola, por ahora en Canadá no tenemos un infraestructura para la célula fule de heydrogen. en mi provincia Ontario, no hay estación de servicio. A solo 2500 km de distancia en mi oeste en Alberta, solo hay uno. Prefiero la pila de combustible de hidrógeno y no puedo esperar hasta que esté ampliamente disponible. Salud Ahmad

Mr. Ahmad, thank you for your excellent review. I prefer to use reliable charger as opus liitokala nitecore. It’s reliable dependable than using this headache modules. Anyhow this is my opinion. Greetings to you from Saudi Arabia.

[@robojax]

you are welcome. this is mostly useful for Lead Acid batteries like car battery or battery for solar systems. Thanks for sharing your opinion.

[@rosekreuze]

can i use this as a ups?

[@robojax]

No you can't. UPS works with AC and this can sense only DC. if you sense DC from an adapter, it has capacitors and the power will turns OFF in about 1 or 2 seconds. So it will not work. unless you modify it by adding AC to DC converter to measure AC only and then it will react fast. Right now it will react very slowly to AC shut off.

[@rosekreuze]

Robojax oh seems alot of work, i thought it can be used like a solar charge controller without solar but dc input instead. you know to cycle my battery pack charging and discharging without interruption while using like a wifi modem

[@robojax]

can you pleas when you say "discharging" what do you mean? Are referring to using the power from the battery by the system. or really just wasting it as discharge?

[@rosekreuze]

Robojax sorry for the late reply. yes thats exactly what i mean i need something in-between the battery and the diy 12v tv which the module charges the battery and onced fully charge the module switches the tv back to battery as the relay turns off
