Nicely made video!
Great that you mentioned that a spot welder is recommended for connecting the batteries.
Li-Ion batteries can be dangerous if overheated, for example they may catch fire or explode months later.
We can also use a cheap 2x18650 battery holder, then we don't need to do any soldering to the batteries,
and when some years later the battery capacity becomes too low due to aging, it's easy to open the lid and just
replace the batteries. The enclosure might end up just a bit bigger.
I use exactly same looking heat gun (I think it was sold as "embossing heat gun") for heatshrink tubing, works great!
The voltmeter shows 7.9 V at 13:46, and then after unplugging the power supply, it goes down to 7.4 V = 2 * 3.7 V, and 3.7 V is an almost empty battery.
But you had them fully charged with your NiteCore charger before building the UPS. Why is that?
This is a cool project, I especially liked your enclosure.
An extra feature that could be added is a power-good or power-loss signal.
If the UPS is used for an MCU (e.g. Arduino, ESP32 etc.) or a single-board computer (Raspberry Pi, Beaglebone),
they could use that signal to realize that power was lost, and schedule an orderly shutdown, for example.
A single-board computer ideally would need something more fancy, e.g. a Beaglebone, if it would shut itself down on power loss,
won't restart automatically when power comes back. Therefore the UPS should have it's own MCU with simple logic, e.g. send Beaglebone
the signal that power had failed and battery is low, wait a fixed number of seconds, giving the Beaglebone chance to shut down properly,
then actually turn off the output (using a MOSFET). When power is back, it should turn the output back on. There are various edge cases
such as handling the cases when power comes back during Beaglebone shutting down, or power going out again while Beaglebone is booting up.
Cheers

We need to set boost convertor voltage to slightly lower than tha power adaptor voltage. Else router will use power sources which have the highest voltage. And battery will keep charging and discharging.
Well done sir, this is almost exactly what I have been trying to build. The only differences are you have a 3d printer, and my abilities are not as advanced as yours. 11 out of 10 stars, very well executed.
czcams.com/video/LJTpQGp4Fmk/video.html
Highly informative and well structured, I'm definitely gonna purchase all the stuff and follow this video.
Great idea to keep our routers running even in the case of a power outage. Thank you !! I will try it even I do not have a 3D printer, I think that a normal PVC IP65 box will be fine
Thank you
This is what I need... ThankYou 😀
Glad, it helps you.
I theory, a very good idea.
Just some concerns. Typical setup is 1 fiber modem at 12v, and 1 wifi router at 12v. Each of those draws 1 amp. So running them together you will do 2amps.
I do not think that battery pack will last very long. Maybe 30 -40 minutes of backup power. Consider using 4 x 20700 cells. 2 sets in series, and then 2 banks in parallel. In South Africa we have daily outages due to rolling blackouts. (aka loadshedding)
these outages is anything from 2 to 2.5 hours. And sometimes the power fails at a municipal level where the outage can be 3 - 24 hours. My max outage was 4 days.
I am in South Africa as well and agree with you. Some modifications to suit us in SA.
I know it may sound crazy but... I have a 12V 7Ah battery lying around. Do you think a similar circuit can handle such amps? I'm planning to connect Wifi and a 12V LED strip for ambient lighting to it.
Congratulations on the project.
Which controller can I use in place of the TP5100 for a 3S3P system?
For the diode i would just put heat shrink over the whole thing
But that's just preference...
And good job!
Thank You.
Hi, good video and neat job.. But why you connected positive 12V in with the 12V out directly? (8:59 as you show on schematic) I mean you should have had connected 12V minus also right?
Awesome project i have been searching for such... good one.... subcribed
Awesome work bro! Subscribed
Thank You.
Hi, nice video but I have a quick question. Why did you add that direct line with the diode between input and output? I mean, I'm not entirely sure, but when you have current going through that line and the switch is on, don't both currents from the input and the batteries are added together which would double the current at the output? Isn't easier to just get rid of that direct line and let all the current go through the charger module to that parallel connection between batteries and switch? That way, the current would always be charging the batteries until they'll full and depending if the switch is on or off, the UPS will be on or off in the same way no matter if it is powered by the batteries or the wall. Thank you!
Here's a much simpler solution: Use a 12 volt car battery and a 12 volt automatic battery charger.
1) Connect the charger to the battery.
2) Cut the low voltage cable and connector off the wifi router power supply and connect the wires to the battery observing correct polarity.
3) plug the connector into the wifi router and plug in the charger.
Done!
The battery always supplies power to the router.
The charger keeps the battery maintained
If the power goes out the router will stay on for days if not weeks or months.
Simple and effective and anyone can do it without all that extra cost and gadgetry.
Building 2 of these for my 10inch mini network rack.
Brilliant
Well explained 👍👌
Hay, rõ ràng, dể dàng áp dụng, nhưng tôi khen nhất ở phần chạy phụ đề tiếng Việt.
My power input would be 12v 1A adapter, and power out would also be same, this will not charge battery right?
Your video and methods are very nice, it would be great if you do a load test and confirm.
Also, efficiency is also very important factor.
Excellent! Couple of questions:
1) What exactly does the BMS board do? Why can't we connect the TP5100 directly to the Lithium Ion battery as well as route it through the rocker switch, etc? What exactly is the role of the BMS board? From what I could see in the product description of the TP5100, its already a battery charger with overcurrent protection etc, so I wasnt clear what role the BMS board is playing.
2) Do the inputs and outputs of the TP5100 share a common ground?
3) Do the inputs and outputs of the LM2587 boost converter share a common ground?
1. It only checks for the overcharge voltage of 8.4 volts but it doesn't know the status of each cell if you use it for 2s. If the battery is not balanced you can potentially overcharge once of the cells if you are not using a BMS. Once cell could be 3.8v and the other one at 4.6v and TP5100 would still think everything is ok because it is still seeing 8.4 volts.
2. I believe yes.
3. I believe yes.
Very nicely explained and a great idea! Thank you. Was there a reason for not using a bigger ups 12V battery instead? Perhaps it would have been too big and heavy?
You are correct and expensive too.
@@opengreenenergy Hey! Please get in touch with me! I need you to design & manufacture 2x units of these units for my company. I urgently need it.
My contact details are in my bio. Please get in touch with my. It's for Sophos XGS 116W.
What about using enhancement mode mosfets instead of diodes re less power loss?
Nicely done
Thank you
This is a good idea but I think it would be wise if you had a switching circuit that switches to ac wall power when it is available as the way it currently is would be harmful to Li ion batteries in the long term
Good job bro 👍👍👍👍
Hi, It’s safe to leave the BMS plugged all the time? *Even when the battery is fully charged
Hi, what are the 2 1n5822 diodes for?
is it advisable to use BRC 18650 UltraFire 3.7v 6000Mah in this setup?
Sir can we keep this ups in continue power supply ? And it will auto switch to battery power when power is off..
Great Video. Thanks for the info. can the bms and tp5100 modules combined ? if yes what type of module it can be replaced with ?
I have no idea dear
How would you change the design for countries that need to power a fiber modem and wifi router at the same time? Could you build something so that it has inline charging ?
UPS Used only during light off ?? Orther Wise used automatically used power supply ? I'm right ?
hello i have modem plus router so i will use splite cable but both of them have .500 amp so high amp can damage my modem and router or not and if then how i can reduce current
I looked but I did not find, you can tell me where you ordered the wire stripper thank you.
so where did you used the XL6019 boost converter?
Superb video 👍
Thank you
Nice, keep it up,
Thank You
This is certainly a better design than the one made by the English CZcamsr by the name SORIN where I suggested him to use diodes to stop the reverse flow of electricity which he omitted. But, the most important question is whether we can leave this UPS always ON and connected to the power supply or not?
The reason I am asking this is that I have read that charging module like TP4056 (you used TP 5100) has an issue where it will keep on charging the Li-ion batteries with full voltage even though they are fully charged(the Red charging Led will keep ON continuously) if some load is connected like in the case of UPS such as yours which can be dangerous. TP5100 might also have the same issue although no one till now have tested that.
Also, I would also recommend using a fuse as an extra layer of security to make sure that the IN and OUT power remains within limits.
Thank You for your feedback.
@Milan Maharjan @Milan Maharjan It doesn't work like that. Adding Extra module in between won't work. The issue is that the power is continuously being drawn through the battery as there is no relay system. So, the module thinks that the battery is not fully charged and thus keeps on charging. But unlike lead acid batteries that can be left charging safely for longer amount of time. Li ion can be quite dangerous and can get heated or burst into flames if kept charging continuously. It also kills these li ion battery faster. So, for now I would suggest that either you use a small lead acid battery(like the ones used in mosquito rackets) in place of Li ion with some changes or just use this for backup in emergency instead of using it as UPS and leaving it charging indefinitely.
My brother, I have a PowerBeam device that works on 24 volts and the router works on 12 volts. I used a UPS for them in three batteries and has three sockets, the first is 24 volts, the second is 12 volts, and the third is 9 volts. Usb 12 volt and USB 5 volt to charge the mobile
Is it possible to use car battery 12V DIY as UPS for router and DVR for 6 cameras?
if you want to add more batteries to extend the capacity for 8 hours, what else do you need? besides the batteries? Different BMS?
My router is 12v 2amp, I need it to work for at least 8 hours
I will upload a new video soon, with higher backup. Please keep in touch.
@@opengreenenergy Me too I need that. I will wait for your video.
@@opengreenenergy Subcribed! btw :)
@@opengreenenergy that would be great waiting for the next video
sir can i use mt3608 boost module for my router as my router consumes 1.2 ampere plz reply waiting for your reply 🙏🙏🙏🙏🙏
This is not a UPS but a Powerbank. A UPS has everything under automation. It has to be kept plugged in at all times and provide battery backup within miliseconds after a power outage. This will ONLY be possible by using a relay... a UPS without a relay is only a powerbank. By the way, Open Green Energy is one of my favorite channels. He is working very cleanly and explaining everything in detail. Thank you.
he used diode may be they will work similer to relay
@@sanjaypatil3097 Sanjay jiii... it's apples and oranges. Totally irrelevant.
Wrong : a relay is too slow to switch from a power source to another without interrupting the power to the router. The way it is done here is the right way to have a true uninteruptible UPS with zero downtime. The only negative side is the simultaneous charge/discharge of a lithium battery bank which will degrade the lithium cells fast. The alternative is to use the older but safer 12V lead battery
@@enerbot283 Not wrong... a relay backed up by a capacitor will just do just fine providing a smooth transition.
@@enerbot283 Wrong: this is why a capacitor is placed right before the relay. This eliminates the downtime as much as the farad value of the capacitor.
Great work! I'm going to make it this weekend using your video👍
Thank you Aditya..
Share your feedback after making..
Bro we need 2 outputs one for wifi router and another for optical converter
If you could make these and sell them surely you will be able to get alot of support. Fantastic idea and explanation. What was the cost to build it. Take into account more batteries.
If power cuts then automatically it will on or to be on manually
Hello ,
Very good work.
This is with regards to V1 of which I couldnt find the video.
"There are a lot of circuits out there that show the use of the TP4056 as both a charger and a load driver - Not Good. If a load is attached to the battery while charging, then the TP4056 may not detect when the charge current has fallen to C/10. So it could continue charging - this could be dangerous.
You should never use the TP4056 as a charger and as a load driver at the same time."
I would not encourage anyone to use TP4056 for charging and discharging at the same time.
Is it safe to plug in Power adapter 24/7 ?
Good for WIFI security cameras.
You are correct.
Hi,
1. Will it protect battery from over charging?
2. Will it switch from main to battery mode once main power cut?
Yes
What would we do without indian guys like you. Thx mate
what is the approximate weight of your case?
Hi, great project. Do you sell 3d printed box?
No, I don't sell.
Can this be plug in all the time? Or we have to turn it on by manual when power cuts off?
Yes you can plugin for all the time. No manual operation is required
Big Liiiii❤❤❤iiike for you 👍
Great work bro 👍💯
But too expensive 🧐🤑
Good job but I have an question can I use 4s bms for 12v output?
You can use 3S, in that case you can use a buck boost converter instead of boost converter shown in this video.
can we make the same with 19 V 2.3 Amp?
what shoul i need to do if i need only 5v output
Sir can i use 1n4007 pls replay
From where can I purchase your DIY version 2.0 modem ups
good one , but why to remove the 12V adaptor , is this not having Over charge protection ?
No need to remove the charger, I have shown to demonstrate that without power the router is working.
nice i like it great video. how can i get an output of 12v 5amps
If I get you right, it means that I won't need the charging and booster conversion units if my input voltage is the same as the battery voltage and same for the output voltage required. Am I right?
Battery voltage is not fixed, it will slowly go down while being discharged so you need a booster to make sure the voltage is stable. You could get away with the charging buck/boost module if you have the exact voltage needed for charging.
I think you should connect the voltmeter to the output.
Can I buy this unit from you directly?
can I do this in a breadboard?
Great work... Will it work for my router which is rated at 12V-2A? And if i want 2 output one is 12V-1A and other 12V-2A, will it work? If no thn what changes i need to make plz suggest.
Yes, it will work.
You have to use two DC output jack.
But you will get less backup time. Backup time can be increase by adding one more battery pack.
I would be glad if u reply
Bro , please make a video of making a mini invertor for charging mobile and wifi modem , using bike battery ( rechargable ) .
i tried it today...for some reason reverse current is blocking input voltagr..so batteries are not charging...diodes are working as expected what could be reason?? where do u think i am doing wrong?? Thanks in advance..!
12:15 Open Green Enenergy that's where the extra energy come guys...
Es una buena idea, pero la realidad es que el router solo durará unos 5 minutos encendido, mi opinión, es que si se han esforzado tanto en un proyecto, donde hasta han impreso la carcaza en 3D, pues que hagan algo funcional, con una batería de moto o auto, porque muchos con poco conocimiento, van a emprender este proyecto solo para terminar desilusionados. Y he visto que tienen uno con batería de moto, pero no la carga. Metanle más ganas, y presenten un buen proyecto,que sea funcional.
Nice project am also trying in your device maximum battery backup how much? , Insted of two battery I can use 4 battery is it supports?
I am getting 2hrs 15min for my 7W router. Yes, but the charging time will be increase. The maximum charging current of TP5100 module is 2A.
How many hours it can give back up
When battery charge continues down battery voltage down together and then the outout of voltage booster voltage down.. so, i need a module whose provide stable 12volt output
Sir I want data card Or dongle with battery , sim card slot and emovable external antenna is there any device like this please give me a sagestion
I love how. Ghetto this is yet functional
On which software can I implement this circuit?
Where can I buy it
hi, i have NETGEAR X4 R700 router with 12v & 2amp. is this ups work for my router? Does he get into work immediately or does the router disconnect and then go up?

There are ready made wifi router ups available in flipkart/amazon for those who can't build one.
Hello, very well done. One doubt... We are connecting two power sources in parallel. They won't be equal in Voltage. And as far as I know, it is not allowed (or it is not the best practice) to connect in parallel two different voltage (one from 12VDC wall power supply and the second one from LM). Ok. They can be very close to being equal but not 100% equal and there will be a potential difference)
You are correct, this is the reason for using of diodes.
@@opengreenenergy Ok. Thanks. Now is clear. So voltage on LM should be lower than on AC/DC adapter? In this scenario as far as we have mains our device will be powered by ac/dc adapter. How big difference in voltage should be (in case using diodes pointed in your solution)?
