The battery holder idea impressed me the most. Any steps towards ease of right to repair in the design of a device makes sure less items end up in the landfill.
Nice work. I'm looking forward to watching the 4.0 version with the mosfet for turning off the step-down converter while on battery power. Regards from Brazil.
Thanks for the video, i executed the above and found
1. Reverse flow of current from battery to XL4015 during discharging, added a diode to counter it, since diode has very low voltage drop, it started heating, added two diodes in parallel to make it work. i,e Fuse ---|>---OUT+ of XL4015
2. In case of any issue with 4015, current load would increase suddenly as battery would start discharging in addition to existing 12V input, suggestion to add a fuse before the final output.
3. There was significant drop of voltage ~2 V across LED, hence removed LEDs from the circuit.
Thank you for this video. It has helped me solve the issue with my DIY wifi router project. Unlike your, I was using a relay to switch power between the battery and mains. However the issue with this design was that the relay would not switch off immediately. This caused an issue where the wifi router would shut down temporarily before restarting . But by using your approach of using a diode instead of the relay at the output, helped eliminate the switching problem of the relay.
Thank you once again.
This is by far the best presentation of this kind of UPS, a useful guide for both experienced an novice hobbyists.
Great project. Congratulations.
In my case, I will assemble without the switch and the LED display.
The system will be automatic. When power is out, this system will supply power to the Wi-Fi router. And when the power returns, the UPS will recharge 18650 cells.
But I must put more cells in parallel, because I also use a fiber optic modem and I want more autonomy.
My router is a TP-Link Archer C5.
Greetings from Brazil.
Thank You.
You can add more cells to this circuit too.
Adjust the charging current as per the requirement.
That Schottky diode drops the voltage of the input adapter to significant amount that the load(router) starts drawing current from XL6019 boost converter even if the batteries are fully charged
Well done mate!
Thank you dear.
@@opengreenenergy Hey. Greetings of the day brother. I need you to build a ups for me. 12v 12.5a 150w. My c0nt@ct details are in my bio. This is urgent. I'll purchase from you.
The way you present is so good. Maintain this quality.
Thank you dear
@@opengreenenergy what amp fuse is used please tell..
Brilliant presentation and excellent quality of work. As for non Engineers, like me the video will be easy to understand for a DIY project. Would be appreciated, if the material cost would be mentioned, starting the next project.
Glad you liked it! Thank you for the feedback
@@opengreenenergy what amp fuse is used please tell me
What amp fuse is used in the circuit?
I simply connected my mi 20000 mah power bank to Wi-Fi router and its working!. I cut USB cable and attached to male round cable. I took shorter cable to avoid losses. Router input 12volt 1.5amps.
Thank you very nicely explained. But one doubt though, how it swicthes from external to battery power when no external input ? It seems both external and battery powering together ?
This is perfect for us who work at home
This time you have taken many precautions and looking at this V3.0 I think it won't have many unexpected consequences like reverse current etc. The only thing I am curious to know is whether you are using it continuously powered up from the mains socket? Also, I have come across relay modules that switch ON the battery power automatically when the power goes off and then turns the battery off when it's online. It is of particular interest because it switches off the power completely to the batteries if the mains power is ON.
I have not completely understood the Relay system for now but it looks like a perfect candidate for UPS. You can take a look at it for your V4.0. Other then that, do let us know if there are some issues in your regular usage of this V3.0 UPS. Nice improvement!
Yeah, I am using it continuously powered up from the main socket. Still now I have not faced any problems.
I have tasted it with relay, but during switching, router starts rebooting. So I discarded the idea, thinking to use a MOSFET circuit to switch between mains and battery.
Thank you for your valuable feedback.
@@opengreenenergy Happy New Year! When will you release the details of the MOSFET modification?
@@opengreenenergy I thinnk the reboot issues is due to relay switching latency. It can be avoided with a solid state relay
Hello sir
Why you chooses 2S - 7.4V pack instead of 3S- 11.1V pack
It may affect battery life
Also conversion efficiency is less
You can also use regular powerbank with dc dc converter. If it has powerful enough output. If powerbank supports qc3.0 with 12v output. There are special cables that tell output circuit that 12V power supply is needed. So you need such cable
Cool i wanted to make ups for my 12v cctv cameras 1 for each unit. I need like 30 of these.
What was the total cost of this project v1.0, v2.0 and v3.0 ..?
And also how was the battery backup respectively?
1500/-
What is the use for XL4015? The charging circuit is already inside the BMS. What is the need for XL4015?? Please explain
I like all your videos,
But my wifi connection has extra POE
Connector so how can we make for that type of router ? Pls reply
Can you send a picture of your router ports to my email?
opengreenenergy@gmail.com
Very Nice work. I have a doubt about the connection diagram.
- What is a use of direct 12v connection with a diode going to the output? As it will cause two 12v outputs merging at output (direct + boost converter) considering switch will be on all the time(I believe it suppose to be on). Will it divide the load between boost converter and direct connection?
I have seen some other similar UPS which does not have that direct connection, as boost converter is always providing the power(incoming power as well as on battery).
Whichever is higher will go through from the diodes. Always keep adapter voltage more than battery so that battery voltages are no consumed.
Very Good work and nice explanation!
Just wondering why you have chosen to create 2s battery pack with 4 batteries, I made a 3S battery pack with each cell of 2600 Mah. This way we can avoid both buck converter and boost converter. I assume every router has internal voltage regulator so need to boost voltage to absolute 12V. Please share your thoughts.
Yes
Using 3S pack of 11.1V having voltage of 12.6 at battery full condition
And having low cutoff of 9V in BMS
So it lasts around 6-7 Hrs for any regular router
Here both Buck converter and boost converter are not required
Only Voltage regulator or single boost converter at output is needed
You are best teacher ❤
Thank you
You are doing great job bro,
this is not a automatic system!! it is continuously giving output mains & converted supply..
I am looking for an automatic switching system like a UPS.
I have made wifi router in completely solar battery out put with relay circuit... but sometimes solar battery run out.. at that time wifi router will connect with mains but it use to rebooting!
Great Video. Please make a power bank using LiFePO4 that can be charged using car 12V output. This way it can be charged and power the dashcam at the same time. It will also work as a mini UPS for Dashcam in parking mode. Well Done!!
Is it possible to buy this? What you have made?
There is no power cutoff when the battery is fully charged. Won't that drastically reduce the battery life by over charging?
Bohat clear work hai apki bhai....❤️❤️
Thank You dear
Xl4015 output Don't you need a diode? Because if the electricity is off it can hit the current from the Battery Battery
Just one word: Excellent..!
Thank You dear.
This messy wiring kills me. But you have a new subscriber cause this is a great idea.
I'm getting hardly 20min backup
Add more battery for more backup
This looks lot better & Stronger than the ready to use UPS in the market , You got me subscribed to your channel Bro, Great job & I like the quality of work, Can you please tell me the total cost & can you Please build me one unit for me & Ship to me, Thanks in advance 💐🙏😊
Thank you so much. I have many questions regarding the cost.I will make a list and reveal the total cost soon
Your video is really very nice . Sir in my power bank , i have used 3 18650 battery in parallel , can i connect 1 volt meter in these parallel connected battery or i use 3 volt meter for 3 different battery
Thank You.
Connect only one volt meter.
Nice but i hope you'll make the latest of this.using additional 4 bat in parallel and with Balancer.. thanks and will be waiting.
I have question about voltage booster module assume, we gave 11.1v to module and get 12v in output if it suddenly get 12 volt in input then the output voltage remain same to 12volt or increase?
Bro ,can we use lifepo4 batteries ?i think a single cell can have upto 6000mah capacity,at about 300₹ ...rate of the project is one of my concerns, that's why i'm asking
XL4015 to battery pack do we need to add diode for reverse current flow? For example i have xl4015 with voltage and amp display so my display is on every time even i am not in use and xl4015 input i got voltage from battery 🔋 all the time.
I can see voltage at the input of xl4015 when it is not powered . it is reverse powered from battery. can i add one more diode at the out of xl4015 to fuse to avoid reverse powering?
Hai can we use 1N4007 diode in place of IN 5822 Or connect diodes in parallel to reach to high amp. Please suggest
You can use two 1N4007 in parallel. The voltage drop will be higher than the 1N5822.But the circuit will work
Whats the value of the Fuse? and what kind of fuse holder are you using? whats the size of the heat sink? Link please! I'm buying all the components from amazon/ebay to built it like you did!
You are an inspiration!
Thank You so much.
I am not getting the fuse holder link on amazon, but you can use this type of holder which is better than what I have used.
Amazon Link: amzn.to/3fSGli8
Fuse Rating = Imax x 1.56 then round up to the next rating available.
I have used a 5A fuse.
@@opengreenenergy awesome ! keep doing these videos! we learn a lot!
Good one.👌 Maybe some vent holes?
Great effort 👌
I have two questions on this video
1. As u know there is a landline output so can I connect my landline to the router while using the mini ups? (NOTE: hardly I receive one or two calls in my landline per week means there is no much usage)
2. We know that when power goes it automatically works on UPS's battery but when power is back does it still work on battery? My concern is battery might be over charged as we use this ups 24*7 hence battery life will come down
Plz clear my doubt plz
If you use BMS then Over Charge/Sort-circuit etc can manage by this (BMS)
Beautifully presented
Thanks alot brother I was looking for this stuff u made my day.
Glad I could help
You didn’t explain brother how the diode will work like relay. I think it’s constantly taking power from both sources because I checked it, do respond ❤❤❤❤❤❤❤
woah very efficient but what about the heat generated by 1n5822, and the boost converter is it acceptable
Can i use this project to supply a 12v 2,5a router? or i need to change the circuit?
Please correct the link to your Instructables link.
The link you currently have here takes one to your V2.0 UPS:
www.instructables.com/DIY-Mini-UPS-for-WiFi-Router-V20/
The schematic for V3.0 is different from the V2.0 version.
Also, when the "main" supply shuts down (due to power outage), and the power out switches to the battery, is there a drop in the supply to your router, causing the router to reset / toggle switched on state?
Thank you.
It would have been more fun to create if you've have mentioned link for products delivered or indian supplier as many will not get product locally so it's impossible to create one! :(
Can you please suggest good soldering kit. Thanks
Solder On.
Very nicely done, can this power a UPS with power rating of 12V 5A?
what is the value of fuse ?
Awesome project nice work , how about doing one with 2 outputs and more batteries
Very nice but what about the current output? It should be matching with the router input right?
I am a beginner.
Current to the router fron the battery depends on the output voltage. You do not need to regulate the current seperately.
please tell me the approximate weight of the enclosure box.
Main body 60gm and Top Cover 30gm.
Why not use 3S battery… that way we can mitigate using the buck and boost convertr, and maybe use a zener diode to give constant 12v. Please let me know if m wrong.
Yeah you are absolutely correct, we can do that. I am designing a new version, where I will use 3S battery pack.
@@opengreenenergy where do you buy your electronic parts and components from? If its online can u please share me sites that u have used apart from amazon.

Hi Debasish
Thanks for a brilliant video. Ive been making this project all day and it seemed to have gone well, however I have a problem! :-(
Im getting power output regardless of whether the switch is on or off, if the mains power is connected Im getting 12.4v (regardless of whether the switch is on or off), with the mains turned off and using battery power, I get 9.4v when the switch is ON and 8.4v when the switch is OFF.
Ive checked the wiring over and over and over and cant find a problem. Im sure it is me and Im quite tired now, could you make any suggestions of what I might have done wrong?
Many thanks
John
You need to adjusted the voltage on the step up module by turning the golden nob on blue component.
Isn't it better to use a 12.6 (3x18650) setup I stead of a 8.4v setup ?
Because most modems require 9v or 12v.
So that only 1 buck converter is needed. Can be charged using a 12v adapter directly.
Thank you very much for sharing the valuable project . I'm from Kolkata . May I use a 7809 IC from the 12v for another 9v supply for my ONU or other way if you suggest .
Instead of using a linear voltage regulator like 7809, I will suggest a buck converter of your desired current rating.
Because the efficiency difference between the two is huge
@@opengreenenergy Thank you very much for your wise suggestion .
@@opengreenenergy Sir, my ONU's current retting is 0.6 Amp. Have Buck converter any current retting ?
Great job in this one, thanks for sharing it with us. Can you use the same setup if you need to have 2 out DC jack ports ? Like one for 1.5A and another for 0.5A ? Thank again.
Thank You. You have to use two boost converters.
@@opengreenenergy Thank you very much !
@@opengreenenergy Can't I just have one boost converter with two outputs in parallel?
Very nice! Everything clear and well described. Thank you.
Glad you enjoyed it!
what amp fuse is used please tell
Nice work finishing
I created this project and it's working great. But if I remove charger from the battery, it always takes power from battery and battery starts draining even my power source is attached. Why is this happening? Is it because of power adapter voltage is less than 12v due to the use of schottky diode? or there is some other reason? Please elaborate this
This is great! Can you do a 19V 1.75A one please?
Question, this circuit maintains float voltage? Which we all know not good for Lithium to be maintained at max voltage all the time.
Hi, Thanks for all the videos you made on these series. I have watched till v5 and gone through the instructables. I feel.this is the one I Should make it.I tried to check the components in the suggestion some of them aren't available. To start I don't see 2s 8A BMS, I am trying to understand the difference between 2s 10A or 2s 8A and 2s 3A. It would be great if you help me finding the right components.
2S 3S 4S etc for cells in series means 2 cells 3.7 +3.7 =7.4V 3 cells 3.7+3.7+3.7 = 11.1V to take more current cells can be connected in parallel and current capacity will be enhanced but not the voltage. In series voltage adds up while current remains the same.and 3A 8A 10A etc is the current capacity for the BMS. Hope its clear.

Could You add functionality to this mini ups with configurable delay time that will cut of power output after specific time of power input loose?
Well done. Comparable if not exceeding a commercially produced product. Would you ever consider selling this in a kit form or even a completed product?
Still now I have not thought for selling.

hi awesome video. i wanted to make such ups but didn't have idea thanks for your video i able to make for my use. i also make vidoe about that ups. with your permission can i use ur video reference and upload my homemade ups video on my channel?
I see one problem with the circuit. The diodes that limit the current to flow back will get hot if there is a bigger power one the load. I made a similar project but with lead acid battery and i had problems with diodes. A relay would be better to switch between power sources
Diodes are rated at 3A current, so anything over that would get it hot. Keep the load within the limits.
Nice project.
Bhai how you are mounting heat sink on ic with help of cooling past or double side tape
The heatsink already have conductive tape.
I will recommend to use cooling paste.

Thanks for this!! I made the V3 powerbank!! It's giving me around 3 hrs of battery backup(due to old salvaged batteries)
But there is one problem if I empty the battery completely, the adapter cannot charge both the battery + power the router. Due to lack of current the XL4019 starts oscillating and LED starts blinking.
Do you have any links for a more powerful adapter? Something like 4 or 5 Amps?
Thanks 👍
Ensure there's difference of 1A current. E.g charging current 2A, output current 1A. See if it solve the problem.
I'm having the exact same problem but turning the switch off and then on starts giving the output. Did you ever solve the problem?
@@MobeenQureshi sry didn't get the notification but I solved it quite a while ago.. I bought a 60 watt brick.
12V 5A
From Amazon, a company called Bectro (bectro powersupply SMPS)
Now I upgraded the original setup to include two switches one that disconnects the battery and another that cuts the power to the voltmeter.
I took the SMPS and built it inside the housing and added a low voltage 5volt fan (it's not connected to the backup) and a few heatsinks over the IC (robu had a really good sale so I bought it from them)
Is this available for purchase?
What is the name of the glue used for easier soldering? 3:19 please
Doubt: Shouldn't the XL6019 be directly connected to BMS P+ ? The switch could control just the voltmeter. In the current scheme, the volt meter will drain the battery needlessly when external power is off.
You are correct.I will suggest to use a separate switch for volt meter and XL6019.
Otherwise, the boost converter also drain some energy.

Thank you brother
What changes do we need to make if we want to increase the battery capacity. Maybe like I want to use 12 batteries in the configuration of 3s4p??
But this is not an UPS since there is no power loss sensor. If the toggle switch is always on. The boost converter and the wall charger simultaneously give 12v. If the toggle switch is off, when there’s power loss the boost converter won’t kick in.
