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.
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.
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.
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.
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.
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.
Just one word: Excellent..!
Thank You dear.
Very nice! Everything clear and well described. Thank you.
Glad you enjoyed it!
what amp fuse is used please tell
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!!
The way you present is so good. Maintain this quality.
Thank you dear
â@@opengreenenergy what amp fuse is used please tell..
This is perfect for us who work at home
Lovely job mate !
Great video, very useful for router backup power.
Thank You
Very kind my friend thank you.
Thank you friend.
Bohat clear work hai apki bhai....â€ïžâ€ïž
Thank You dear
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.
Cool i wanted to make ups for my 12v cctv cameras 1 for each unit. I need like 30 of these.
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
Very tidy work!
Beautifully presented
Nice work finishing
Very good explain thanks
You are best teacher â€
Thank you
Great project
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
â@@opengreenenergy what amp fuse is used please tell me
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 ?
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
love it and looks cool
Thank You
Amazing!!
Thank You
Very good quality project
Nice video mate.
Cok iyiydi vallahi emeÄine saÄlık baboo
Thank you
Good one.đ Maybe some vent holes?
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!
Thankyou brother
Good work
Great đđ
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
Nice one Brother, hat's off to you
Awesome project nice work , how about doing one with 2 outputs and more batteries
Good ups for wifii
Nice project.
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?
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.
This is great! Can you do a 19V 1.75A one please?
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 đ all the time.
nice ,great video. can i get but output to be 12v 5amps? planning to use one for my rock pi nas
Superb dear... Just awesome
Thank you so much
Is it normal for the Diode in the +out of the charger to heat-up? Thanks for your video i already made my mini ups but the diode heating up makes me a little paranoid. â€ïž
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.
Great effort đ
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)
Can i use this project to supply a 12v 2,5a router? or i need to change the circuit?
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
great video đđ
Thank You
woah very efficient but what about the heat generated by 1n5822, and the boost converter is it acceptable
WOW â€ïž nice đđ
Thank you
@open Green Energy
Do you think you cam make a updated v3 battery capacitor tester video for 18650 (and other) batteries, and in v3 you add an internal resistance test?
I loved the v2, but the one thing it lacked was a way to read/test the internal resistance of a cell.
Thank You for the feedback.
I will consider your suggestion in my next revision.
@@opengreenenergy Thanks! I am currently using Lii-500 to capacity test, but there are no "cheap" testers for internal resistance, Would love one that is based on Arduino and is more of a "plug and play" test style so I do not have to manually calculate the IR using V1 & v2 calculations by hand with a multimeter and resistors. .
Very nicely done, can this power a UPS with power rating of 12V 5A?
Nice video
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??
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?
Great video, can i use xl6009 instead of xl6019. Please reply
Super Bro đđđđ
Nice work brother
Thank you brother
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.
Nice
Does is work when battery is fully discharged ? Because Router keeps blinking if Original router adapter is used as input to the UPS
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?
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.
Good bro
There is no power cutoff when the battery is fully charged. Won't that drastically reduce the battery life by over charging?
Xl4015 output Don't you need a diode? Because if the electricity is off it can hit the current from the Battery Battery
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 đđđ
Thank you so much. I have many questions regarding the cost.I will make a list and reveal the total cost soon
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.
@@mbsingh4597 Thanks đđœ
What will be the charging module if using battery in 3S configurations?
Hi mate the instruction link is from the v2 is there for v3?
Bro I have a doubt. I want to charge my battery pack with 2.5Amp but I want to get 2Amp as output. Is the charging circuit (XL4015) is different from output circuit? Do we get output as 2.5Amp when we set 2.5Amp in XL4015 module?
Bro ,can we use lifepo4 batteries ?i think a single cell can have upto 6000mah capacity,at about 300âč ...rate of the project is one of my concerns, that's why i'm asking
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.
What is the use for XL4015? The charging circuit is already inside the BMS. What is the need for XL4015?? Please explain
Question, this circuit maintains float voltage? Which we all know not good for Lithium to be maintained at max voltage all the time.
Brother I have lithium battery pack,3s bms module,xl6009 buck boost converter module and xl6009el step up module .Possible to make router ups from these materials?
Thanks alot brother I was looking for this stuff u made my day.
Glad I could help
Good
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.
@@opengreenenergy that is probably for the best, with liability issues at least. Still, very impressed.
Thank you.
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
Very nice! :) I'd like to do it, but I have an Asus router that needs 18v, and a Mikrotik GW that needs 12v. To power up both can I use 2 step-up converter (XL6019) both connected in parallel to the batteries?
Yes, you can use two separate boost converter in parallel
use 3s pack and set buck converter to 12.7v and boost converter to 18v
it works !! I'm electronics engineer it works đ
if you add two parallel boat converter efficiency down to 70% :(
you can wathch sorin diy ups (CZcams channel) he made with Asus router
@@dhairyasoni7467 definitely đđŒ
Can I add 2 output terminals ... because I have router plus modem...
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 đ
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)
I couldn't find that kind of diodes locally, if I use the regular ones, can I connect the power source to the the step up to compensate for the voltage drop of the diode? What should I change from your schematic?
You can use a regular diode as well just take a diode with 3A rating. Diode voltage drop wont matter here as most modems and routers are fine with as low as 10 volts.
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.
@Open Green Energy I have xl4015 5A with only voltage adjuster. I cannot adjust the current. Will it work?
What should be the XL4015 ratings if im using a 3s bms with 6 no. 18650 cells
Hi can you do 2 output from this UPS because I have Router with Modem so 2 output required simultaneously :)
Very nice and useful tutorial.
My router and dc adapter is 9V 0.8A . can I do it without the XL4015? Thank you
Most 9v or 12v adapters has 9-9.5 and 12-12.8v voltage.
Do you think it is possible to use a 5V 2A charger and use the TP5100 to charge the 2S battery pack and make this mini UPS to work? The Router uses (I think). 200 Mah. Greetings
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?
Hiii buddy .. just wanted to know 1 thing about the part that is booster .. its getting very very hot .. i provided 5v to it and then set the out voltage to 12 volts .. and then connected it to 12 volts led strip .. once it is done ... the led light was barely lit for 10 to 20 seconds .. when I touched the boosters IC .. it was HOT so hot that I could not even touch it .. just wanted to know if there is something wrong with my booster .. please help me ..
