Hey Ahmad :D I've been waiting for this kind of module! Thanks for sharing that is a good news. Don't hurt yourself on the ice ;) Happy end of the year !
Hey Co Fa, nice to hear from you again buddy. Lol jut connected the wire wire and it wa shorty circuit. Happy Monday 😂
Thanks. you gave us new ideas as always. keep it up
Thanks for this, it clarifies a few things.
You are welcome. The best thank you for me is to subscribe to my channel. Your subscription is stamp of approval and my videos will be suggested to more people and this will help me. I appreciate it. thanks❤️
Thanks for the video. I was looking for such a device.
This isn't a really a uninterrupted supply, the device will restart when switching happens. This can also be achieved with a 12v relay and a Diode only.
may be you did not watch it. it has other features.
Keep up the good work.
Very helpful video
Thank you for this extensive review. Please review this module XH-M350, which do the same thing and explain why It does not contain a diode to protect from reverse voltage spike (Back EMF) caused by relay's coil. Are the capacitors in it do the job?
Oh Ahmed...I listen for the quality information given in your videos; but I watch for the entertainment value (smoking output wires at beginning of video) 💪😅
LOL. I am glad you liked it. wires short circuited while I was recording.
Informative video.
Very good information. Im hoping YX-850 will work with a device Im working on that needs pass through charging. at only 5v for YX-850 to work, a 2S lipo battery at 7.4v should be just enough to get the switch to work fine when the battery is needed.
Indeed it should work.
niceeee explanation
Really good review, I have a 48V battery but its nominal voltage and its full charge is around 54.6V, does the YX850 can handle that voltage for the battery and charger?
Thank you for super video...😍😍
Will 804 module work with 24V battery + 12v power supply? Or both power sources should be the same voltage?
Seems like great modules...thanks Robojax! Hey, which module blew up at the beginning? And was it your mistake or a bad module? Thanks!
it was just two wires got short circuited. LOL
1:14 Shout out to electroboom
I could smell that smoke! I oops a lot when I was younger
Okay. So I see a problem. The product description says the the the same voltage is required for the power supply, the battery and the load for this work. But a 6v battery requires a higher voltage for it to charge - 7.5 to 8 volts. Then the battery supplies 6volts to for example a 6volt Lighting circuit - the Load. How can this work then if the voltage must be the same for the supply, the battery & the load? The battery won't charge and will eventually go flat if this is the case. What are solutions so you don't have to keep changing the battery?
Hi sir, can I remove the diode and use two different voltage inputs (5v adapter OR 3.7V LiPo) to power the esp32?.
my professor
👍👍👍💓From 🌎 India ⚘🤲
1:13 boom 🤣
I have the 801. Can I simply add a diode to have the 850 version?
If yes, what type and specification of diode to be used with an 8Ah Lead Acid battery?
Thank you very much for your educative video ,but I've a qn for the ac side, can I connect 240v ac directly (without using adapter ) , ie live and neutral instead of +ve and -ve
no you can't. it will die immediately.
if i don't want to charge to battery i need to cut off diode from yx850 module ? ( i use independent charger for li-io battery pack)
Can the module be set to output power only for battery, so light could be on only when there is power failure?
Hi, Thank you for your video.Can this handle more than 10A if I change the existing relay with the high current one? The load will be around 30A.
Hi, yes relay is the determining factor and the diode. Change it as well or just in parallel to it add one more diode
Does it charge the Batter and supply output when adapter is active..??
Great video Ahmed!.
Maybe you know what the difference between the two modules is with the yx- 804 module?
yx- 804 is exactly like the one i've shown.
Sorry, I mean with YX-1708.
Thank you.
Can I connect the YX-x850 battery side to a XH-M604?
I'm looking for a module with USB C input. So simple.
Where can i buy a yxx850 module? I searched internet and didnt found it. Also this could have 12 or 14 batteries ? and charge with a 30W solar panel?
Hey Robojax! I've been following you in your YT Channel quite recently.
I just wanna know if there's a power switching module that has minimal delay in it? I'll be using this to power my router 😃
Some other says that I could add in a capacitor to kill the delay? But I am not sure if that's a safe approach for this kind of load since the router is running for 24/7.
Let me know your thoughts please. Thank you
Hey, the cheapest way you o remove delay is to just add capacitors. That is the case where a mechanic switch such as relay is used. Depending on the load (router in your case) starry with for example 1000 microfarad and test it and add more in parallel to that capacitor until you get uninterrupted result.
@@robojax Hey man really appreciate your response! I am not that geeky with this kind of stuff but I have the basic knowledge. I made a visual plan on what I wanna build. I hope you can check it out and hope you can chime in and let me know your thoughts if it's feasible and can withstand the 24/7 use as it's intended for a wireless router. Also can you please check if the placement of the capacitor in the image is correct? Here's the image/visuals: bit.ly/3M6u61h
I hope this will work as intended so I can start building it. Excited to build this actually :) Thank you so much for your help!
@@robojax where is capasitor, baterai or output/load?
Very good video, can I ask for the circuit diagram of the module or datasheet ?
this video was replacement of everything you asked. Non available.
I've been waiting for this module for almost 2 weeks which the seller took 5 days to ship out! but he sent me the wrong version which i didn't actually need a charging feature. i noticed both the positive inputs are connected via a diode. if my assumptions are correct, if i remove the diode it will no longer charge my batteries but won't affect the UPS feature? and also, can we add a capacitor on the output to make the relay switching seemless?
Yes correct. That is the only differences between them
to decrease the drop we can add a capacitor, right?
any suggestion what kind of Capacitor would be best suited (like a minimum value, i know it will vary based on loads)
I am just curious
Are you asking about the time between power loss, and the relay switching? One amp = 1 coulomb per second. And one Farad = 1 coulomb per volt. C = Q/V and Q = I*t. So one farad will drop 1 volt per second per amp drawn from it. C = I*t/V. If there's 0.2 seconds between power loss and the relay switching, and the load draws 1.5 amps, for a 2 volt drop you'd need 1.5 * 0.2 / 2 = 150 milliFarad. This is a massive capacitor. I think this module is really only valuable in situations where total momentary power loss is acceptable. Or for very low current draw devices. Maybe a 12V device running at 100 mA can accept a 1V drop, so 0.1*0.2/1 = 20 mF. Still a large capacitor, but more in the realm of possibility.
Hi brother Ahmed can i connect 3 lithium battery by connecting 3s bms I want to use it for wifi router backup.. please replay me.. thanks a lot..
i was wondering, are you using a bms for your battery pack? or is it safe without one?
Always use BMS yo be safe. If you don’t use it you may make mistakes and batteries will get damaged
Can I use a battery pack which has a BMS attached? Let's say a 3S BMS and with a 12.6V CC-CV charger as the power supply?
Load is a wireless router rated @ 12V.
Let me know. Thanks!
Yea you can. You have a look at this module which see if it works for you ua-cam.com/video/iM9oMdNBX1o/v-deo.html
Brother, I want the battery not to charge. In that case, if I open the diode, will all the other functions work?
YX850, Can we put 2 batteries, one in DC another in battery terminal?
can this be use using lead acid battery?
is there a version of the same module but without the relay and with faster switching like a mosfet.
Yes there bus UPS that operates with battery. Just click on channel name and then click videos to see iy
@@robojax I didn't find the video. Can you tell me correctly? Or comment what the name of the module is? Sorry for the trouble and thank you for your attention.
Can you tell me the version/model of the module? Thanks
sorry but what can i use for the battery to not over charge or drain empty? for safety purpose if i leave it for long or use it for a automatic emergency light . thank you
it depends on how many battery and how much current you want to work with. here is a system for 2 cell 18650 battery ua-cam.com/video/vQIsc8-Uoio/v-deo.html
Could someone suggest a part number for a switcher relay that could handle 25v minimum?
Through hole. PCB mounting it ofc.
As you said , switching of RELAY take .6 second, so it not ideal to use for microcontroller board. because everything time RELAY switches , it will reset the microcontroller. How we can remove this problem ? do we need to use can big capacitor ?
or can RELAY be replaced with any MOSFET or SSR ?
I have the same question. I hope he sees it.
Can we add 12V capacitor across the bulb so that it can temporarily keep the bulb light up during the switching?
Try it.
For yx x801 u said that the load should only be between 12v to 48v but you also said that the ac power will also be directly supplying the power to the load with the same voltage? That means at the output there would be 220v when on main power supply i.e ac? But the load needs only 48v?
please watch again. it seems you did not understand that we have operating power and load.
Thanks for this video.
Any new module which has uninterrupted switching?
One suggestion needed from you. I have lfp battery ups 20v 4amp. And currently using with diode mbr20100ct from charger (cc cv module) to battery to stop reverse flow from battery to charger. Till now it works uninterruptly perfectly without any problem. Added some fuses at input and battery output. So is it safe to use only with diode or should i add some switching circuit?? Please reply. Thanks for your time.
if you module has CC feature, the battery is protected with you set Voltage constant. Now you have the diode, you should be good. to charge the battery fully, there is a voltage of about 0.6V or more drop across diode, keep that in mind and added that to the CV so the full voltage reaches the battery. you should be good specially you have also a fuse. stay safe.
@@robojax yes there is cc cv and bms protection.and drop voltage is also considered. Thanks you so much for your time in replying. God bless.
you are very welcome. God bless you too.
What happened to that smoke Lol
yx850 ACDC fan can be driven with this circuit
What if we replace the relay with a solid state relay, will this eliminate the 0.7 second delay?
theoretically yes it should turn ON immediately if you replace it. But I have not tested it and it may have other side effects. try it .
Hey Ahmad, I am wonding can the "AC Charger" be replaced with a feed from a vehicle.
Say from just a Cig Socket. Cheers
Hi, the battery always needs charging voltage. if you supply voltage higher than the battery rated voltage, the batter will get damaged. this module can facilitate connecting the the load and the battery.
Is it possible to add some capacitor for eliminate 0.7 delay when switching? if possible, how to connect them?
as I mentioned. this is mechanical device. The only way to eliminate the off time, is to have enough power for the load. Find the total equivalent resistance of the load R=V÷I, V=voltage, I=Current. if you found R=0.1Ω then The 𝜏=RC where is C is capacitance in Farad and 𝜏 is time in Seconds. , get C=𝜏÷R, and if you want to get 𝜏=0.7 for example, then C=𝜏÷R=0.7÷0.1=7F, and 7 Farad is equal to 7000μF. So would need 7000μF capacitor to be connected to the load to keep it the voltage to 63% of the original voltage. if load voltage is 10V, then it would keep it at 6.3V for 0.7 seconds. if you want to increase the time, then increase the capacitance. it would be HUGE capacitor the voltage rating of capacitor should be the voltage of load. Let's see if it works for you.
I made a similar relay module. I added a small capacitor 1000uf at the output. It became uninterrupted. The capacitor should just be enough for that millisecond of switch
@@ktestable wow, that's what I wanna try as well, what's your load current and voltage? I want get rid of restarts for my router 12V 0.5A when switching to battery, can you suggest a capacitor please?
Any EXPLANATION for what happens at 1.15, and how it can be prevented? thanks.
that part was funny and I suspect no comment as he was embarrassed!
the modules are actually useless for routers due to their delay/ I wish I've seen this first before I made my "mini Ups" project
on 804 the relay stay on all the time, dosnt cnnect only when out of power, bad very bad, no trust
now i wanna see if 850 use other way around
If I add this module with solarpanel's battery ..will it work?
I mention all voltage and capability. if your solar panel is within the voltage range yes it will work. by the way it seems you have written your name is reverse. I assume Rizvi is your last name, then it should be second like Ahmad Rizvi. Many people in Indian, Pakistan and Bangladesh think the name order is being reversed when you write it in English which is not true. Biden is the US president's family name. So it is written Joe Biden NOT Biden Joe.
How does the computer chip know when to stop giving power to the full battery
this does not. it will disconnect only when the power is OFF. you should have your own charger. Use this instead ua-cam.com/video/iM9oMdNBX1o/v-deo.html
Hi sir is there an uninterrupted module available?
Hi, here is one I tested ua-cam.com/video/iM9oMdNBX1o/v-deo.html
i need to use First battery and the dc secondary... i can?
If you mean to use batter instead of power supply, yes you can
@@robojax Yes because i need to use first battery then later the dc (i have hybrid solar system) and when the batt is finished i want to use the DC supply
@@m0hd_ i don't have certain applications for that. but it definitly works either way you want it coz i tried it already
Does the battery will drain even if I'm not using it?
Yes it does but very minimal. I may have mentioned it in the video.
Sir how to make automatic switching
If we r using 4v battery 3W 8.97v 3A solar panel
1:15 xD
Will the relay "REALLY" handle 10A?
of course. it is a mechanical switch. when you buy it look the specs before baying it.
I want bord like this but by mosfet and without latency
And that would be USPS.
Can it charge the battery too??
I have explained all features and now I don't remember. So watch and get answer.
IF THE INPUT IS GIVEN 15 VOLTS OUTPUT HOW MUCH VOLTS ARE YOU?
It does not change the voltage.
@@robojax If the input is given 15 volts, is the relay strong, sir?

what is the difference between power supply and charger
Power supply just provides power. Charge checks the voltage and current of the battery and change them in order to charge the battery properly and protect it from getting damaged.
@@robojax
so if I want to use this board as UPS for IP camera
I have to use 12V battery + charger , and not just power supply.
or maybe use battery with charge protector .
1:14 what happens ⚡
it is for fun.
Wht happen burn u video?
someone make diy version schematics of this please :}
why you even need to make it? this is so cheap that if you make it, it would cost you 10x more. You can use Arduino instead.
@@robojaxcurrently in India we are not getting orders shipped from china as the Indian post disposes all the chinese shipment packages because of ban and in custom tax section writes that it was disposed because of public safety which is clearly vague and i dont wish to loose more money in this process. So if some kind man from Internet provides me schematics of this relay i could locally buy all parts and components like 12v relay for 1 dollar 7 pieces and make diy stuff for myself
bad bad,
You do something wrong
Hello sir good Video I have a question about esp32 i want to make an auto switch between battery an dc power i have used this x804
ua-cam.com/video/XA8qaMbrQ6Y/v-deo.html but like it said in the video it have 700 ms beteween the 2 state and the esp32 reboot how can i do for the esp32 do not rebbot
then you need a real Uninterrupted power suplly shown in this video ua-cam.com/video/iM9oMdNBX1o/v-deo.html
