Extremely informative, if only other content creators were as descriptive as you :/
lol he doesnt even tell what component he use in video
Finally a guy who isn't powering the router directly from the battery
Why is it bad to power a router directly from a battery?
No matter how big is your battery is it will provide only amount of current the device need* and he is saying this because all other people are using lipo battery without any protection or proper voltage regulator and you can use battery directly in EMERGENCY coz batteries drop voltage while using and device components well get heat up if there is insufficient voltage so its better to use regulator and booster 👍🙏
@@boymichael10 I would suppose it would put unnecessary wear on the battery. You have electricity, you should use that directly, not through the battery as an intermediary.
Bhai do u have whatsapp
Thanks very much for sharing this project. Looking forward to building some of these.
While under battery power, is there a voltage which shuts everything off to protect the battery from over discharge?
Masha-Allah you are then best Most intelligent Pakistani Engineer of TH-cam, also I'am very very happy that you fullfilled my request, One more thing many many congratulations for your شادی 🤗😍
Best wishes for Usman and Mrs Usman ♥️

Very clean design, good work!
I need this on 5v output and use small solar panel and li-po batteries. Awesome board!
Question 1. What if I have a load of 5A to 7A Approx
Hello, can I use it with Bms 3s module? Does this system stop auto charging when the battery is full.
This is really neat little PCB, id also wish I could just order some. But I think I might try and make this, also been wanting to try JLCPCB for some time.
i will used this proyect thanks for all Sr. Saludos desde Mexico
Oye que diodo usaste para el D5? El que dice 9.1V+6.2V
At what voltage will the battery stop charging? My concern is that the voltage drop across the bridge rectifier will mean that the battery will never get the full 15V, hence the ups that is calibrated to stop charging at 15V will not stop trying to charge it?
Hello Mr Usman, I finally received all the parts including the 15vac transformer. Like someone else noted, I had to use only one 9.1 zener at D5 for K2 to switch. The circuit runs fine in the normal power mode. However, several minutes after removing the AC and running on the battery, K1 relay starts clicking or chirping and the charging LED blinks, the 555 timer starts getting hot. Any thoughts what might be wrong?
Thanks for your help i got it done works great. Great video thanks for the extra info
How i can purchase full readymade circuit? and from where i can get this circuit?
Great design! I would like to modify for powering a 2A device, do you have a suggestion of part number for a suitable 5A regulator component to replace the 7812?
Yes I would too. Majority of DC home appliances now runs at least on 2A. Please share what we could do.
@@hamhumtube Haven't found a suitable 5A replacement without redesigning the circuit but the 78S12 is 2A as opposed to the 1A of the regular 7812, so might help it go a bit further.
I'm a subscriber and thank you for the project video and the PCB Gerber files. I would like to customize this schematic to my particular needs, do you mind sharing the EasyEDA schematic json file for this project?
Hi Usman, I'm a subscriber and thank you for the project video and the PCB Gerber files. I would like to customize this schematic to my particular needs, do you mind sharing the EasyEDA schematic json file for this project? Thanks again.
how much maximum ampere does it draw out? so we can operate more than one device?
What is the transfer time of the circuit in millisecond? From Grid to battery and from battery back to Grid..?
you uploaded a video after a long time
i was missing you
can you able to supply the board with all components fixed?
Nicely done and explained
Hi sir ia m trying u r Circuit 12v ups , it's working wonderful thenku so much
Can you help me I'm looking for more info on the parts list numbers 2,6 and13 need more info please help Thank you
Very good project 👍
excellent ....thank you for sharing the making of board ...
What software do you recommend for a newbie, to view the gerber files? Many thanks.
A nice one. But how did you decide the values of each components used here
AMAZING!!! Is there any available of this in complete assembly?
hello in the component list n4 GBU8005 I can't find it on the market
is the one in the video GBJ 2510 the same?
very good, working like it says, thanks!!!
The best design that I found. Can I use a 2S BMS or 3S?
Awesome man I really like it
Hello ! I need a 2a load capable one can you help please ? What should i change
Hi Ahmad. Thanks for a nice project. Could you give more information about D5? I see there is only one Diode in the circuit, but you have indicated a 9.1V+6.2V diodes in series. Can you clarify?
It is clear. Use these 2 diodes in series and connect in place of D5.
Does it provide any protection against power surge, distant lighting strikes etc?
what is the output current rating of this circuit. does this manage battery charging also.? I made one on my own circuit, but i failed after some months.
Nice bro nice 😉😉👍👍
HI! awesome work! Its there a way to get the electrical diagram ? thanks.
What about the delay when switching to battery?As we are using relay switching delay will be more. Better to use power electronics switching component like IGBT. Over all hardware design is good.
How you are giving power directly to router from battery without regulating the volts and current isn't it fry the router?
Good idea 💡
How i can purchase full readymade circuit?? Is it available in the market??
yes i also need a readymade circuit!
what's LSP and USP stands for?.. Is it for charging and cutoff voltages?.. lsp set for start charging and usp for stop charging(full)?
Does it cut off at 10.8v when Batt get low
how is the power transfer possible from mains to battery without any delay?
Is this a dumb question...
Is it feasible to power about 100w of devices (server, WiFi, etc)
off a 12 volt to 240 volt inverter;
powered by a 12 volt battery
that is kept under constant charge via a 240 volt battery charger?
I'm thinking , as a UPS, it should 'work' but (putting aside efficiency ) maybe there are some longer term issues?
what is the load of input supply please tell. i want to make it for home.
ohhh wooow cool bro ,, very useful
where do you get the parts from?
Does this have over discharge protection for the Lead acid battery used in it ? Because deep discharging Lead acid battery will reduce its life span for sure.
It is for router, which automatically shutdown at low voltages.
Awesome Video 🖒👏👏👏
One question wont the 5w resistor heat up long time use?
can i use a 1A or 2A transformer as the supply power?
Hello guys, a newbie here. can i ask if can i add load on it. like having 1 modem, 1 router, 1 switch.... or more. how can i get a consistent 12V 1A output on it?
Nice project but. How to calibrate if I don't have the voltage regulator???
Considering that the power-supply can simultaneously charge the battery and provide sufficient power for the load, you can connect the load directly to the battery and design the charger to adjust current based on the requirement. This way you can avoid those relays and the supply to the load will be smooth.
This will wear out the battery capacity, to preserve the battery, we should have as minimum charging cycles as possible
I agree with the other person commenting as well. We should not use battery 100% of the time, only when needed. A nice special feature would be to drain the battery about once a month to keep the battery healthy. However, knowing my luck, the power would go off once a month while draining the battery lol
Thanku bro circuit wonderful working
How can i purchase the fully completed project?
When i made this circuit, i couldn't set the 15v usp pot.. led is not turning off.. i am using 50k trim pot instead of 20k because it wasn't available here in our local shop.. is it because of that?.. i am able to set 13v lsp on same 50k pot.. let me know what's the problem.. components are all working none damaged and checked every connection
I was having this issue too (USP trim pot never turning off the LED), but have discovered the problem was due to a batch of NE555P. Now replaced with a chip taken from another source it works. Using a 50k trimpot won't be the problem, I think, though may be wrong.
Can this ups support external hard disks, i have several external HDDs that require power adapters to supply 12v 1.5amps to power them. I have frequent power cuts in my area so im looking for something similar to your solution.
Use a 5A regulator instead of 7812
Hello, am trying to use the 12V 7AH battery (in UPS) and router wall adapter as inputs; both of them controlled via 2 12V Relays for switching the input for powering the router. There is a capacitor to handle the voltage drop during relay switching.
The problem is that the battery is showing a voltage higher than adapter (sometimes 13.3V); the output of adapter remains between 12.2 - 12.4V.
Is it safe to use the output voltage of battery to router or should I use a 7812 voltage regulator in output?
capacitor detail??
Can i used here 18650 lithium battery?
And is it online?
Thank's for explanation
Good man keep it up
is there battery protection if battery goes down and should be cut off!
Thanks for helpfulness soo helpful video
Nice work 👍
Can I connect one 12v 1amp ont and 12v 1amp router at a time.?
Buddy I need to buy this complete project from you i.e. 15V 4A transformer , 12V 7A Battery and the Circuit as well, kindly let me know how and the price as well.
Hello dear, how much current does the battery charge? And how can I increase the current at the output?
The list of components is confusing. Can u provide the links to purchase all these parts?
Nice post.. thanks
Could something like this be made for a 100amp 12v system?
Bro. You are doing great job.
but I have made same like yours but sometimes wifi router is rebooting while switching from mains failed. why? wifi router is 12v 1.5 amp.
What is the output of this ckt ??? Because I am using Router(12v 1.5A) And Modem(12v 0.5A) . Can I use its o/p for router and modem ?
Reply please
the input filter capacitor negative is not connected to anything why?
Is it really access internet and need wifi access card?
Sir tell me
I want to make it
is there any input for using a 12v dc power supply?
Thanks for the great video! Noob question: can you add more batteries for a longer running time?
In parallel, yes, using batteries of the same rating.
-Make sure voltage of the two batteries are the same (can use pcb to charge separately before next step if needed)
-Connect batteries positive-positive & negative-negative.
-Connect pcb to positive of one cell & negative of the other (if using > 2 cells, connect pcb to positive of the fist cell & negative of the last cell)
i wish i could bought your project instant dont know where to find those things
Hai i use your circuit. But while I remove battery + terminal from circuit the charging led should keep on. If the full charging led on then all out put voltage should zero. Why this problem occur. Please help me.
In case there's a failure on the battery (maybe battery cable is broken or other battery's failure)
are these circuits can still work normally without connected to battery?
Yup.
Did we able to get a ready-made circuit
The relay would not trigger unless I used just one 9.1V zener for D5, (not sure why the 9.1+6.2 did not work). I've also found using a ~2200uf capacitor across the output will stop the router resetting when it switches. All working now, it seems thanks again for this project, very informative.
does that mean the router will not stop working or the moment when it switches?
@@LinuxUser123 that's what I meant, in my experiments with this project adding the capacitor across the output prevented the router from resetting during the momentary power loss before the relay kicked in.
@@electronicsluckydip gotcha
Hi this nice, need the following info: 1). price complete board,
2). Can we use this for circuit, LiFePO4 battery 12.8v , I don't use lead acid type battery
What about multi-outputs i mean if i want to add another modem to it
Sir, what components do i need to change for Jio 2.5A router?
Nice but why no inbuild calibration unit and no Fuses?
Can this be used as a cctv power supply?
What changes needed for 3.7V battery ?
Hello are you selling this PC Board and if so How to order it?
Mr. Usman, I have ordered the PCB and I am trying to order the BOM, but I cannot find a 115vac/15vac transformer. Can I use a 115ac/24ac instead?
No, only 15v
can we install router and onu both in this circuit?
I have a doubt, please clarify. I have a working UPS (the regular one that we use for computer).
During the power cut, I don't like the idea of UPS running on DC , then Converting to220v AC which inturns converted back to 12 2A DC by the modem's power adapter.
Is it safe to Run the modem directly with the SLB 12v 7Ah Which is connected to the UPS? Not only during power cuts but all the time (even when the battery is on charge) ??
If you run your modem direct on battery, it could be damage. Because during charging, voltage can reach upto 15V. Which is extra for a 12V modem.
@@EasyHomeMadeProjects
I understand during the charging cycle the voltage is higher,
But is it Okay to connect a standalone (not connected to ups)12v 7Ah battery to a modem that requires 12V 2A??
Do you have any suggestion like a simple voltage regulator module that could do the job and not damage the modem even during charge cycle??
You can use xl4015 circuit to adjust the outpust voltage and the current from the ups batter as like your adapter then simultaneously you can charge your battery with your ups bode and also you can use the 230v inverter and the battery connected with the above circuit which I have mentioned and connected to the modem .
Only you can do to unbox your ups and make a dc connection from your battery with out removing ups boad connection and close your ups and connect xl4015 circuit and make adjustment as per the requirement modem with screw driver and multi meter and switch on
sir the provided link is not working for gerber file download and component list
Can you make a simple inverter circuit ? It's helpful 😊
Bro i want to know about the circuit board u made n how to get one
Do you have it complete soldered pcb? I mean selling it the complete unit?
Hi Great video!
say can i play with input voltage? or i must have 15v 4A? can i play with the type of battery?
i ordered everying should be here in the next month or so :)
Only use materials that are same as shown in video
@@EasyHomeMadeProjects i have a 5A power supply will it be ok?
please make a same type of circuit for running a laptop which doesn't have battery. Before of this type of circuit only need a booster circuit which will produce 19v from 12v high Ah battery.
