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?

[@goldstandard7406]

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.

[@satreaaji]

[@modelsfirst]

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?

[@oneinabillion654]

Hi sir, can I remove the diode and use two different voltage inputs (5v adapter OR 3.7V LiPo) to power the esp32?.

[@incubus3286]

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

[@robojax]

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.

[@incubus3286]

@@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!

[@rosekreuze]

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?

[@robojax]

Yes correct. That is the only differences between them

[@sanjaybatra6593]

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 ?

[@OJovemFilosofo]

I have the same question. I hope he sees it.

[@incubus3286]

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!

[@robojax]

Yea you can. You have a look at this module which see if it works for you kzbin.info/www/bejne/n36coICag6eLZ9E

[@Raafiu4]

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

[@gizmoguyar]

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.

[@raihanahmed723]

Brother, I want the battery not to charge. In that case, if I open the diode, will all the other functions work?

Can we add 12V capacitor across the bulb so that it can temporarily keep the bulb light up during the switching?

Try it.

[@sulemanshah94]

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?

[@robojax]

please watch again. it seems you did not understand that we have operating power and load.

[@aldetta0095]

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

[@sanketsk]

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.

[@robojax]

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.

[@sanketsk]

@@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.

Hey Ahmad, I am wonding can the "AC Charger" be replaced with a feed from a vehicle. Say from just a Cig Socket. Cheers

[@robojax]

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.

[@SUBEGAP]

i was wondering, are you using a bms for your battery pack? or is it safe without one?

[@robojax]

Always use BMS yo be safe. If you don’t use it you may make mistakes and batteries will get damaged

[@Medos996]

What if we replace the relay with a solid state relay, will this eliminate the 0.7 second delay?

[@robojax]

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 .

[@Kris0725PL]

1:15 xD

[@homegeographic5351]

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

[@christinomalaysianto9326]

Is it possible to add some capacitor for eliminate 0.7 delay when switching? if possible, how to connect them?

[@robojax]

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.

[@ktestable]

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

[@stseraf]

​@@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?

[@tech.capsule]

If I add this module with solarpanel's battery ..will it work?

[@robojax]

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.
