I am now 79 year old.I made this project 2 years ago and it is working excellently.We, here in South Africa , experience regular power outages and this project has been most useful.Many thanks and God bless you.
I hear you and feel your pain. I was born in South Africa, though I left 37 years ago, and watch the shocking news continuously. Good luck with the Escom rebuilding or replacement! How can you live without reliable power is beyond me.
I have really enjoyed seeing the evolution of this project from the first one that you built through each iteration it has gotten better and safer. Thank you for sharing your progress with us!
Hi, thanks for sharing a nice & useful project with us. But I think in your design two thing u don’t design it carefully 1. 12v Output whens the the mains powers is active: u set input voltage 13 volt and its directly connected to output by a diode. If the foreword voltage drop is .3v the output voltage will be 12.7 v which is high for the 12v output. 2. power switching : whens the mains on 12v output jack provide 12.7 . Now power goes and battery pack start as u set buck boost converter output 12 v. Thats mean when power switches there always a 0.7v voltage spike it’s not god for router. Suggestion: 1. u can connect input 13v main power supply in input of buck boost converter not to output thus u get always a steady output voltage . 2. U can use electrolytic capacitor in input & output dc port to reduce ripple and get steady voltage.
Thank you for the most valuable feedback. I was also thought to connect the adapter output at the input of the buck boost converter but changed my mind for considering the continuous power wastage in the converter module. But I missed the point that I am not using a 12V adapter at the input. Use of capacitor is nice feedback. I will update all these in my schematic soon.
Hi, i did this project using 2200uf/16V capacitor at the output terminal. But during AC to Battery switching output voltage is increasing to ~17V and decreasing to 12V. What might be the cause?
Thanks for a great video.. This helped me a lot to make one myself. MOSFET idea was great for switching.. I had an issue to find the correct case since 3d printing is costly but found a plastic junction box from electric shop. Soldering worked for spot welder and MOSFET heating was an issue which was mainly due to oversite on diode usage which looped the power back from battery to gate. Thanks again.. Keep up your great work Sir
I tested some projects to make my UPS. With MOSFET, with relay, etc. And as always I had some kind of problem. I did some tests with the XL4015 used in this project and arrived at the following solution that I'm still testing, but so far no problems. The power source connected directly to the input of the XL4015 (for battery charging) and a step up/down connected in parallel with the XL4015 (to regulate the voltage that goes to the router). The battery is connected to the output of the XL4015. In the tests that I did the behavior is the following: On the XL4015 you can control voltage and current from IN to OUT. But in the opposite direction, OUT to IN the supplied voltage is the same as the battery and has no current limit. So while the power supply is on, it charges the battery and provides power for the Step Up/Down. When the power supply is turned off, the energy passes from OUT to IN, providing energy for step Up/Down without router restarting. So far everything working OK, inside the case (without opening for air circulation) the temperature is approximately 30ºC. uploaddeimagens.com.br/imagens/gtpRh_I
@@opengreenenergy I'm planning to put more load on the circuit this week. My goal is to connect 1 12v 2a modem, 1 12v 2a router and 1 rpi4. At least in the tests I did, the modem does not consume more than 0.500a, despite the specification of 2a on the label. But I'm going to test with other devices first so I don't risk running out of Internet and without rpi4.
@@walberjunior hey, whats the ratings of your input adapter and are the batteries getting charges fully as li-ion battery require cc or cv method for charging? what voltage & current have you set in both the convertors for your router? do i need to buy a smps as the whole 2.5amps(my router rating) which comes from the input will be used by the router itself?
@@roshan00778 I changed the project to power 2 routers, 1 rpi4 and 1 esp8266 to integrate with Home Assistant. Until today working very well. The rating if I'm not mistaken is 5A, but it's a Chinese product so it probably doesn't deliver 5A. Batteries are fully charged. The charger I configured for 16.8v@500ma. The converter that feeds the routers if I'm not mistaken is in 12.1V. It depends on your project, how many batteries you are going to use, if you need faster charging, etc. If you can measure the actual consumption of your router that would be great. One of mine uses a 2A power supply, but the actual consumption is no more than 800/700ma. Most products do not deliver what is on the label, but the minimum you need is a 2.5A power source plus charging current, let's say you use 500ma, that is at least 3A real. You can see photos of the project at this link homeassistantbrasil.com.br/t/esquema-nobreak-dc-dc-para-modem-cameras/7769/5?u=walber
Seeing you plug it in I think the box could use some additional support designed in around those areas. Otherwise this was a quite interesting design concept. You could also add a USB plug using the 5v dc for charging phones while the powers out too.
@@369LandXplorer USB ports at routers are not for charging phones, but for connectivity - mine has SATA interface with HDD connected there. USB port would be nice optional extension to your project.
I simply modified my APC offline UPS by replacing the 7AH battery with 2x20AH VRLA batteries and added a small fan to the internals that get hot when the UPS takes over, the 110v to 12 transformation loss is so little and can be disregarded. My cable modem can easy run 24 hours and even longer when power fails, my TV is also connected to it and digital TV decoder so with all powered on i have around 3 hours. Usually power outages don't take longer then 2 hours in my area and are mostly the result of a blown transformer or maintenance at the hydro powerplant turbines.
There's only one more upgrade to this possible now that is to add a schedule on/off feature. If that is done then this mini router ups can undoubtedly the king of all DIY mini UPS projects.
Dang the video presentation was awesome! Looks like ready to be sold Why don't you collab again with PCB Way to get us some integrated boards, would be awesome to get rid of the wires and the soldering process
Amazing work.. thanks for sharing. I will try to build it. The only problem is to find more than 12.6v charger. There are some available with 15v 3a but thoseare expensive. Most of them available are 19.5v 45 w charger which are used for laptop charging. Excellent work once again. Keep up the good work. All d best. 👍
Thanks very much Bhai! I have most of the required components lying around and I already have my own ideas on how to build one. However, your tutorial makes me understand in-depth everything one needs to know. Keep up the great work. Subscribed!
Nice! Only one small problem for us with this one, if the power goes out to our block the ISP equipment in the cabinet outside goes down also. In fact so does our local mobile cell tower haha
@@piyushnagawat24 Yeah some stuff is powered from the road, especially if it is linked to telecoms. BT in the UK have battery backups in various places underground so you can still call the emergency services in an outage.
mobile cell towers never go offline they have emergency Generator and Battery Those acts like big UPS. I have never seen any cell tower going offline in my 3rd world country , you should investigate there must be others reasons cell tower going offline.
Also if you have fibre optical cable they do not require power from the road line/etc to stay online they are directly powered(Its just light inside cable) from ISP. so they never go offline
Hi admin, Can you make our existing circuit with solar power with normal electricity charger also. Case1 : when sun is there powerbank will run on solar pannel Case 2 : when sun is not there or low solar power it will shift to 12volt adapter power Case 3 : when solar and adapter power is absent it will shift to charged batteries. Everything should be automatic.
These projects are amazing and deserver way more views! A really good project would be an all-in-one solar unit. inverter/mppt charge controller/ac input in one giant box. If that type of device had plans, and an easy to order kit tons of normal people would make it, not just hobbyists.
@@kenanelicanov2327battery will take too much time to charge too inefficient. Battery will get damaged after few months. Instead of that use 13v or 14v 15v adapter.
Hey ...this is a very nice project. I just have one confusion ! I might be wrong, but I think a pull-up register is needed at the gate and source pin of the MOSFET. I'm a amature by the way . Please help me about my confusion . Thanks
A couple of things based upon my experience of building this router, first and foremost i am hobbyist it was super easy to follow your instructions and build it. 1. Around mosfet would be great if you can showcase which point gets to connected to where itll be easier i got stuck there and it took a lot of time. 2. Around input power i tried using the default adaptor of my wifi but thats only 12v and its unable to charge batteries beyond 11.4v and its heating a lot. 3. If ill use a 14v supply for input wouldnt it fry my wifi as the power from supply will be connected directly to output
Remember! Most of the gadgets are working on just 12 volts DC power supply, and laptops are working on 20 volts DC power supply, so no need of buying big bulky and expensive inverters. After all every day, science and technology is getting advanced very fast. I've done this same project for my home use, it's very important, no need of big bulky and expensive inverter. Just a 12 volts battery and a charger and voltmeter.
i have done experiments with Nokia G-140W regarding its supply voltage reliable operations. the router works fine with supply voltage from as low as 6v to 15v i didnt try supply over 15v as i was afraid of damaging the router. most router with 12 v input will run perfectly fine with output from 3s bms which outputs 9-12.6 volts.
HI im trying to understand your scimatic, and have a very basic understanding on electronics. Is the mosfet in this design only turned on when the DC input drops is disconnected?
@@opengreenenergy yess I like it very much of your Project's!!!!!! And Please Provides parts link in Decreption. I like u r 12v wifi router UPS !!! please provide me that parts link where I can buy in amazon some parts are currently not avalaibe showing. Please suggest me... Heart fully love u❤️💚💚💚💚💚💚
Hello, Thank you for So Nice & Detailed Video. One Query I would like to Ask Can't we take two 12V outputs at the same which would work for Two Routers Simultaneously. Please do give me a Feedback.🙏🏻 As I want to create it for Router & ONU which would function Simultaneously on Same Backup Ups.
Sounds great, thank you! It's one year from uploading this video - what you will hange today in this project? What parts you suggest to use on similar, but bigger current system? (I know I can "duplicate" parralel system, but it's not best solution). I have roughly 80W of hardware and short breaks in power line supply. Just want to switch off all hard disks to safe position safely - last break make me expesive, as my NAS lost data (I had backup, but bit obsolete) and was not possible fully recover. Recovered just partially.
Hello again, thank you very much for the suggestion to watch this video! But my knowledge of electronics is very basic, sorry. That is why I want to ask you a few more questions to be able to modify your project and adapt it to my needs. To add a 12V 1.5A output, should I replace the second XL415 module with an LM2596? I mean, would I have to have two LM2596s, one for each 12 V output that I want to put on ?. Thank you very much (from Argentina)
Please,what software did you use for your 3d design, love the design but the case is some how big, with the circuit, I fell you can do better by reducing the spaces and adding layers to reduce the size of the power bank an portable.
Hi friend, excellent work, very clear and interesting. Do you have a video to build the box for this project? I´ll be very thankfull with you. Waiting for your answer.
I like what you have done here, I want to build one myself, but I need to have "24V 15A input" and want to use 2X 12v 9Ah Lead Acid batterys as the battery pack, need 2X 20V 4.5A outputs, 2X 12v, and 1 to 2 5v 2A outputs and maybe others, I don't quite understand how the charging Circuit works or how to set it up for this type of setup, any help would be much appreciated.
This is a great project. I have doubt about in this diagram 1. where is the charger for 18650? 2. if it is without a charging controller is it not good for batteries? Please clarify this.
You can use any diode with current carrying capacity more than 3A. Try to get Schottky diode ( SR560) , if you will not get, you can buy any general purpose diode.
I wanna have a router ups and a camera ups but combined. I think I can just turn the converter you used for 9V for my requirement of 5V for the camera.
@Open Green Energy Instructable link is old. and also in description 2S BMS is mentioned. What amp 3S are you using? And in description you mentioned XL-4019 so where you used it? and you haven't mentioned LM2577-LM2596s in description. Description contradicts with video
great job bro 💗😋 I'll definitely try it l.... loved this version 🌝 some more features you can add like green and red led to indicate power and a 16v 1600uf cap at the output which helps not to restart router while cutoff 💗💗💗
@@navaneethanravichandran9161 yes ofcourse you can use relay but switching takes 0.3 ns which cause restart of router. advantage of mosfet is quick switching, required low current low switching voltage. you can wathch v 4 of this channel
Hi, i did this project using 2200uf/16V capacitor at the output terminal. But during AC to Battery switching output voltage is surging to ~17V and decreasing to 12V. What might be the cause?
Thank you so much sir your video very helpful I have one request instead of that battery pack you used is there any possible ways to use 12v 7ah battery Can you make a video of it as I request
You have mentioned 12 to 15 volt input. Most routers work at the highest of 12 volts. Will they survive on 15 volt supply as you have shown 1 power line direct to the router from the power source.?
I see you put Power Mosfets IRF9540 , You said in the video or the descriptions is p channel but actually in the links is showing N channel most, Can you please explain that before I order the things Thanks
Greetings from Indonesia can you make a series of ups full dc input 12v 20a out 5v, 9, 12, 24 without a break if the power goes out with a 4-8 hour vrla battery, without damaging the tool for backup internet devices, success continues, friends
when power failed. instantly stop router and onu. after some seconds restart and working fine. and again power comes not shutdown..... Working continue. whats the ptoblem?
One flow is you have bypassed the 12-15volt input to output in mains mode when power is present and if the input is really 15volt this is going straight to the output and if modem is not tolerate to 15volt it can harm or burn the modem. I think this is serious problem.
Congratulations on using those insulating gaskets, SO many videos rely only on the battery's own thin shrink wrap and solder right on top of it. I make my own gasket using 2 layers of kapton tape and then cutting out the middle with an exacto knife.
Can I use solder instead of spot welder, to get desired cell configuration? Do not want to spend that much amount just for spot welding untill and unless it is very crucial.
Bettar if you use computer smps for it so that no need to manually change over it from mains to ups,computer smps have 12v 7ah batt so that it will work last long approx 7 hrs :)
This also automatically switch from mains to battery. No need of manual switching. The switch is just to isolate the battery pack from system if required.

@@a892728 Rare!
And usually you can throw 12 anyway
Hi, this is a great project, i made this but with an automatic conmutator, with this, battery long live is higher.!! thanks
Hello, Thank you for So Nice & Detailed Video. One Query I would like to Ask Can't we take two 12V outputs at the same which would work for Two Routers Simultaneously.
Please do give me a Feedback.🙏🏻
As I want to create it for Router & ONU which would function Simultaneously on Same Backup Ups.
Super!
Thank you
Sounds great, thank you! It's one year from uploading this video - what you will hange today in this project? What parts you suggest to use on similar, but bigger current system? (I know I can "duplicate" parralel system, but it's not best solution). I have roughly 80W of hardware and short breaks in power line supply. Just want to switch off all hard disks to safe position safely - last break make me expesive, as my NAS lost data (I had backup, but bit obsolete) and was not possible fully recover. Recovered just partially.
Hi, awesome project: a question, if i don't need 5/9v output i can just avoid to add the 2nd XL4015? , thanks!
Yes, you can omit
Quality work bro. Thanks and keep it up
thank you very much sir! freaking good video presentation!
Hello again, thank you very much for the suggestion to watch this video! But my knowledge of electronics is very basic, sorry. That is why I want to ask you a few more questions to be able to modify your project and adapt it to my needs.
To add a 12V 1.5A output, should I replace the second XL415 module with an LM2596? I mean, would I have to have two LM2596s, one for each 12 V output that I want to put on ?. Thank you very much (from Argentina)
Please,what software did you use for your 3d design, love the design but the case is some how big, with the circuit, I fell you can do better by reducing the spaces and adding layers to reduce the size of the power bank an portable.
Best vdo for mini ups.
Very good.. What is the MOSFET for in the project?
En este proyecto puedo usar el mosfet mosfet IRF9540N por el IRF9540 ?
@opengreenenergy one question how can I add a third output of 19V I have a third device I need to backup.
Thank you in advance. Nice UPS work
Hi friend, excellent work, very clear and interesting. Do you have a video to build the box for this project? I´ll be very thankfull with you. Waiting for your answer.
That best one actually..
I like what you have done here, I want to build one myself, but I need to have "24V 15A input" and want to use 2X 12v 9Ah Lead Acid batterys as the battery pack, need 2X 20V 4.5A outputs, 2X 12v, and 1 to 2 5v 2A outputs and maybe others, I don't quite understand how the charging Circuit works or how to set it up for this type of setup, any help would be much appreciated.
This is a great project. I have doubt about in this diagram 1. where is the charger for 18650? 2. if it is without a charging controller is it not good for batteries? Please clarify this.
BMS is itself a Charger and protection module. So there is no need of external charging module !! It's completely safe and secure
Hi, thanks for your video.
What type of 3D printing did you use?
Hello, should i use two buck-boost converter for dual 12v output or the same schematics, just adjust xl4015 to 12v?
Can I remove MOSFET,
if no MOSFET what will happen?
please tell me.
Stunning project.
Thank you
@@opengreenenergy flop project
It would be great if you make a video that shows us how to made this enclosure in fusion 360. Please consider this.
Aur up aur down booster module lagana jaruri hai please help bro
Good work, thanks for sharing.
I didn't get the 1N5822 diode. Is it possible to use other diodes instead? If so, which one to use?
You can use any diode with current carrying capacity more than 3A. Try to get Schottky diode ( SR560) , if you will not get, you can buy any general purpose diode.
I wanna have a router ups and a camera ups but combined. I think I can just turn the converter you used for 9V for my requirement of 5V for the camera.
Does it auto switch to battery mode? I have a sliding door project which works in 12V 5A. Can I use this system as the battery backup for my project?
Is the mosfet irf9540N work at 8.4v ??
because i thought make this project with 2s bms .
Nice project bhi a
Thank You
Nice one, great. Having a query, if I need to use Output of 12V/1A and 9V/1A loads, then what should be my Input 12V adapter max current needed ?
You can use 3A but if need faster charging then go for 5A.
@Open Green Energy Instructable link is old. and also in description 2S BMS is mentioned. What amp 3S are you using?
And in description you mentioned XL-4019 so where you used it? and you haven't mentioned LM2577-LM2596s in description.
Description contradicts with video
Hi,
You are correct. I have to update all the details.I am traveling now, so just copied the description from my V3.0. Sorry for the inconveniences.
great job bro 💗😋 I'll definitely try it l....
loved this version 🌝
some more features you can add like green and red led to indicate power
and a 16v 1600uf cap at the
output which helps not to restart router while cutoff 💗💗💗
and yes don't forget to add heart srink on mosfet as it carries 2amps l, as you know
heat drirectly prop to amps ☺
Thank you so much dear.
I need more valuable feedbacks like yours, I will update it on my project page. Currently, I am writing the tutorial.
Hi, instead of MOSFET can i use relay? What is the benifit of MOSFET instead of relay?
If i am not using both relay and MOSFET means any issues?
@@navaneethanravichandran9161 yes ofcourse you can use relay but switching takes 0.3 ns which cause restart of router.
advantage of mosfet is quick switching, required low current low switching voltage. you can wathch v 4 of this channel
Hi, i did this project using 2200uf/16V capacitor at the output terminal. But during AC to Battery switching output voltage is surging to ~17V and decreasing to 12V. What might be the cause?
5:26 Best BMS ever :D
great project.
hi babe
Very Good...!!!
Thank you
In this project can I use the IRF9540N mosfet instead of the IRF9540?
Nice project ,keep up gud work
Thank you my friend
Love your work
Thank you so much sir your video very helpful
I have one request instead of that battery pack you used is there any possible ways to use 12v 7ah battery
Can you make a video of it as I request
You have mentioned 12 to 15 volt input. Most routers work at the highest of 12 volts. Will they survive on 15 volt supply as you have shown 1 power line direct to the router from the power source.?
Creative video, thanks for sharing :)
I see you put Power Mosfets IRF9540 ,
You said in the video or the descriptions is p channel but actually in the links is showing N channel most,
Can you please explain that before I order the things
Thanks
IRF9540 is a p channel MOSFET. The Amazon description is wrong
Love from BD🇧🇩🇧🇩🇧🇩❤❤❤
great video as usual!
could please explain the use of 1N5822?
I think it's to prevent reverse power flow whenever connected to any device contains battery
very nice, just print PCB standoff for the converts in the box,
Greetings from Indonesia can you make a series of ups full dc input 12v 20a out 5v, 9, 12, 24 without a break if the power goes out with a 4-8 hour vrla battery, without damaging the tool for backup internet devices, success continues, friends
beautiful!
Thank You Angelo
@@opengreenenergyz. h. h. b. n. I.
when power failed. instantly stop router and onu. after some seconds restart and working fine. and again power comes not shutdown..... Working continue.
whats the ptoblem?
One flow is you have bypassed the 12-15volt input to output in mains mode when power is present and if the input is really 15volt this is going straight to the output and if modem is not tolerate to 15volt it can harm or burn the modem. I think this is serious problem.
Please tell me how to adjust the current, should it be with a load on?
Congratulations on using those insulating gaskets, SO many videos rely only on the battery's own thin shrink wrap and solder right on top of it. I make my own gasket using 2 layers of kapton tape and then cutting out the middle with an exacto knife.
great project, thank you for it
Glad you like the video
Can I use solder instead of spot welder, to get desired cell configuration? Do not want to spend that much amount just for spot welding untill and unless it is very crucial.
Yes, you can solder
Can you plz tell me why you use xl4015 module to the charging port ? You could have use a 12.6v adapter
Yes, that can be done
Bettar if you use computer smps for it so that no need to manually change over it from mains to ups,computer smps have 12v 7ah batt so that it will work last long approx 7 hrs :)
This also automatically switch from mains to battery. No need of manual switching. The switch is just to isolate the battery pack from system if required.
@@opengreenenergy ok gud
