- Hi guys! I hope you are doing well.
I made a few modifications to this UPS and I will share them with you in this video. The UPS will switch to battery power much faster now and I used a new PCB for the relay circuit. I received it from JLCPCB. It will simplify the build a lot, so if you want to build your UPS with this PCB, just upload the gerber file to JLCPCB website and place the order.
Feel free to visit jlcpcb.com to order professional PCBs at low prices for your projects. $2 - 2Layers 5pcs; 4&6Layers starting at $5.

Use an comparator to check if supply is less than x voltage and then turn relay on/off based on that voltage. Gives you very fast reaction time.
Great video. I adapted your earlier design but swapped the relay for a couple of P-channel Mosfets (an IRF9530NPbF), one for each supply 12/19V. Much faster switching and they don't draw any current under normal conditions so no risk of burned out relay terminals in the future.
use mosfet not the relay, they draw next to nothing current and drop rezistor wont hot so much, u can get mosfets from old laptop battery, they usualy are 30V and 15A ones
How do mosfets work with this application
@@dinoantonio6100 They replace the relays to turn on the current path from the batteries to the outputs.
What gauge wire did you use for the battery pack? Thanks for replying 😊
@@dinoantonio6100 I had some old 18AWG laying around so used that. Seems fine.
I like your channel is growing and you can have sponsors and using a pcb always better than homemade circuit boards. I like your work please keep it up.
Greetings from the other side of the pond. I'm from Romania but live in FL. I'm glad to see a fellow Romanian building cool useful things. It's what I do all day! (Just no time videos)
Wow thanks you i had the restart problem in my own designed circuit and u helped me fix it
Nice video and great ingenuity ! Well done !
I love this, thanks man! Keep up the great work.
Excellent project. I liked it
thr part we didnt ask for but glad to watch!
Awesome video as always
Hi, I always see all your videos, they are always the best, I'm just from Mexico and I'm translating this, greetings from Mexico
A custom PCB, eh? That's how boys become men 😁
Hi sorin! Thank for share new video
You are a genius please keep up thanks for sharing 👍
Great work!👍

Electronoobs will not like that. pay me or i will tell him 😂😂
Its good to see people make their own design and build stuff. You can make this a whole lot easier if you just have batteries a charger, bms and one buck and one boost converter. Use two diodes into the outputs of the power supplies and adjust voltages just under them. When a.c. drops out the diodes pass voltage and their is zero delay. Can be done cheaper and don't need any pc board or fuses, relay or switches.
Can u explain more for me
great video , good luck
Have you experimented with a digital relay? I don't know if it is faster or uses less voltage, but if it does then it might be worth the added expense.
Sir you took lot of pain and altered the circuit Thanks sir good explanation🌷🙏
3:57 now make a video you taking that with you to the Airport 😊 love your video!

I Agree.
Amazing video

Nice UPS
Good job 😊👍 Awesome ⚡👍
What a cute cat❤️
I've designed a 12V ups system using a boost converter that was adjusted to a voltage slightly lower than the power supply voltage. The boost converter connected to the battery output was in parallel with the wall power supply. So what happens is that the boost converter capacitors were charged to a voltage higher than the converter was trying to regulate so therefore it remained off when there was power. But immediately the capacitors sagged 0.5V under what the power the supply was giving then the boost converter started to deliver power. It worked instantly and it's a simple design.

@@sunilkumar-yq4xn would you like the design?
@@kaumohlamonyane272 yes, for future references.
I just saw your comment I just wrote pretty much the same thing as this. Yep I've done it before too.
Bravo Sorin
You had me at screwdriver.
🤣🤣
Looks very nice and it is usable, i have to have 3x 12v and 2x 19v output do i need to change something or can i just split te 12v and 19v output. It would be nice if you could build one for 220v, but that would probably dangerous?
Hi. For multiple outputs it will need a bigger battery and depending on the needed current, it may need a different design. I will soon make a better UPS with a bigger LiFePO4 battery and more features.
One of those anodised aluminium resitor would look really cool, and there are 100-watt versions and higher.
Hey , thank u
Great project. Does your circuit balance the 18650 batteries ?
yes
Esti foarte bravo
Love your videos. Have you thought about using a FET instead of the relay?
yes, but I wanted to make a video with relays. I also plan to make other type of UPS in the future.
I use mosfet but switching is still slow.
What will you connect to a gate pin of mosfet?
Actually I have same problem when switch from AC adapter to battery mode. I solved it with small bulb or LED connect to AC(with limiting resistor) and LDR sensor(like optocoupler) to activate relay with small transistor. When AC disappeared, the bulb instantly turn off and LDR shut off transistor base then relay too. It take less delay and better efficiency(less current consumption when no load and no charge the battery) than yours.
O solutie pentru problema timpului de raspuns al releului ar putea fi rezolvata destul de usor daca ai integra sursa in cutie. Vezi putin conceptul 'zero crossing'. Din acel optocuplor (eu am folosit H11AA1) poti comanda releul, desigur, mai pui un condensator de filtrare dar macar ai timp de raspuns foarte bun fara a pune o sarcina in plus pe sursa. E doar o parere :) spor la treaba!
U r great bro....i am a big fan of u.......
Hello frd ...can u try mppt using arduino as dry project....
i think if you use intermediate relay it will be better than SRD relay and just need to add capacitor after diodes at relay output source that will overcome relay delay
so it will reduce the current consumption from the 20W 220RJ you use
I just use a really ups for everything the smart UPS from APC
Nice!
Why not just run from battery all the time and just constant rexharge like an avr?
Hi great work by the way, I ordered the PCB's and made this one. When are you thinking of making another one without the relay, or one with faster switching? Keep up the good work. Do you have a new Full schematic of this UPS?
Thanks. I will make a better 12V UPS with no relay, but it will take some time. I'm working on other projects now.
@@Sorin_DIY Thank you sir for the reply, I have enjoyed All your video's and can't wait for more, but I am going to have too, LOL, Keep them coming and thanks again for all your hard work.
Hey Sorin. Can you make a router using single board pc & pfsence?
si acum sa vina si V2 :D, keep up the good work.
Dexter ce zici? Ești tare! Clopoțel direct!initial am dat Subscribe acum ceva timp dar vad ca faci chestii mișto. Eu as vrea sa fac un circuit pt un vobler (pestisor artificial) ceva cu vibrații și flashuri led. Am nevoie de ajutor!
Użyj diody zenera w połączeniu z rezystorem np 1k do wykrywania spadku napięcia.
Lub przebuduj go na topologie online, przekaźniki i przełączanie w przypadku zasilania bezpośrednio urządzeń zawsze powodują dodatkowe komplikacje.
Tak naprawdę nie będzie dużo większych strat jak będziesz napięcie przetwarzać dwa razy, a zniknie całkowicie problem z przełączaniem.
You could perhaps use one of those 50W AISIBO Aluminum Resistors that come with a heat built on for the relay load resistor.
I am also working on a similar Router UPS for my channel so I can relate to your challenges.
All in all, i believe you did a great job with this video. I guess your 0.13 sec switch time is the target to beat....hihihi
Si de unde faci cumperi rezistente capacitoare regulatoare pentru board?
Hello , great video
I've been looking for something similar for a while now (12v mini ups).
but what I always miss is how long can it run on a charge.
I'm looking for something that can run for at least 16 hours on a charge at 1 amp. 12V,
and can be recharged in 8 hours
can you tell me how long your mini ups can run on a charge with a load of 1 amp 12v
and what needs to change to meet what I'm looking for
Hi. this type of UPS will work for about 4 hours on battery backup. I will make soon a better UPs with a bigger LiFePO4 battery and more features.
Hi
Can you make a device for moisture?
Would you try and make a self charging unit
I need this PCB board.
need 4 version with most :)
The circuit looks better and btw i like your romanian accent👍
same problem so am using a 9volt transformer for relay and 1000mf x10 capacitor
Salut imi plac videourile tale si sunt un mare fan a electrictati. De mic m am jucat cu motorase si multe lucruri. Oare unde pot invata electrica sau cum o poti numi:) chiar mi as dori
salut. cel mai bine ar fi sa te inscri la niste cursuri de electronica pentru incepatori. cred ca poti sa gasesti si cursuri online. sau te uiti la youtuberi cum explica si construiesc diverse chestii. dar ai grija, unii fac si greseli (probabil si eu am facut cateva :D )
Can it be used for 24V ?
yes, but it needs some modifications to work with 24V.
Sorin , I faced this issue with relays before , the resistor approach is not that suitable , it is better to use a capacitor dropper to convert 220VAC to 12VDC connected to the relay , the moving to backup battery will be even faster if power outage occurred .
I'm using your old one with BMS and boost converter. That works perfectly however the batteries don't charge and need to be changed every few weeks
think you charge and use the battery @ the same time that why
what BMS board did you used? the one from the video, or from the link in the description? what charger do you use?
7:33 I could not understand what he is going to say.. can anyone help me and explain why the relay will switch faster if the supply voltage to relay is low?
Do you need a relay? I want to make a smaller one with the adapter plugged in 24 X 7
for this design - yes. but I plan to make another one without the relay.
Lol. Love the dog poop joke.
Interesting project, but you may be able to do what I did and get away with something much simpler and more efficient.
Most consumer network equipment doesn't actually require exactly 12v or 19v input. They usually already have internal SMPS dc-dc converters that take the input voltage down to the 5V, 3.3V, 1.8V, etc... that is actually needed by the internal ICs. I have tested my equipment to work down to about 6-8V and up to 20V+ (depends on the input capacitors and specific DC-DC SMPS IC used).
So, all that is really needed for a 'UPS' is a dual diode where one leg is fed from a higher voltage AC-DC adapter (19V laptop adapter in my case), and the other leg is fed directly from a lower voltage battery (2S-4S, or large deep cycle 12V lead-acid in my case). The dual diode will let the higher voltage power source through until it drops below the other power source at which point the backup power source will power the output (with no switchover delay).
I run my entire home network core on this exact setup. A 19V laptop adapter and large deep-cycle 12V lead-acid battery through dual diode powers my Motorola SB6121 cable modem, an Asus ChromeBox running pfSense, a TP-Link TL-SG108E 8-port gigabit smart switch, and a 5-port gigabit PoE switch (through a XL6009 boost module set to ~48V). The PoE switch provides power (and network) to my wireless AP (EAP600), and VoIP phone. I have an external 12V lead-acid battery charger/maintainer hooked up to the battery. I can power my entire network core off of the lead-acid battery for about 4 days in a power outage.
For even higher efficiency, the dual-diode can be replaced with dual 'ideal' diodes, that have much lower forward voltage drop, or even an IC that is specifically made for this exact purpose (i.e. LTC4412).
Very interesting comment!! I recently came around Dual Diode, discovering them actually, they are very handy!! I discovered them while fixing PC PSU. As you explained, they are also used there to get 2 voltages, from same voltage source.
I really hoped your whole idea had a visual tuto, to illustrate the whole idea.
the ideal diode can be build with 3 mosfets instead of the CI. not sure it matters for a small router
Hi Sorin,
Thanks for the video.
Could you please make a video on building a 12v ups with usb module so that i can use it to charge my phone (as a power bank) and use 12v out for the modem
Is it possible to build with more backup?
Also, I would like to know what the backup for the unit you build in this video
Could you please help us with a video in creating a pcb
hi. I plan to build a different type of UPS in the future, with a bigger battery pack and more features.
@@Sorin_DIY much awaited. any date we can expect
Bravo Sorin. Felicitari!!! Daca-mi dai o adresa iti trimit si eu ceva cablaje ce-mi sunt de prisos, tot de la jlcpcb.
Why do you not replace the relay for and SSR? For that consumtion, the SSR don't heat a lot and can be get into a case.
hi. I wanted to make a video with relays. I also want to make another type of UPS in the future, without relays.
@@Sorin_DIY With an ATtiny85 is very easy. A pin with sense (I reccomend to put it into AC, because when AC is out, the condensator can fake the AC break signal, with an octocoupler). And a mosfet for a fastest transmission, at the same time the relay and the desconnection of the mosfet. If you make a board with all, can buy a small power supply from 2A and put inside it.

Hi , for preventing voltage going back to router charger from ups i added a 1N4007 diode which has apx:0.4 v of loss, which lover the output from 11.7 to 11.3 ,and my modem was restarting (not even powering on ) , help me to fix should i change my diode or any thing else..
hi. try it with a better charger, with 12.6V and 2A.
@@Sorin_DIY any other way to fix ,because 12.6v wasnt available in local and takes more than a week from online. so any other way. please help.
@@chandrasekharguntupalli4079 instead of using a diode, change it for a mosfet, so you would have almost no drop in the voltage.
@@felipetomaz1843 i will try it bro
Hello, when you can make 19v output, is it possible to make a laptop power bank so i can use my laptop longer than the internal battery?
Well technically uhhh
U can
But the output from this ups is not even close to Ur laptop's need
I mean the current draw
The laptop needs somewhere around 3.5-6 amps of current
And this ups is made from low- current-output modules
Hope u understood
I will make a UPS/powerbank for laptop, but it will take some time.
@@Sorin_DIY that would be awesome 🎉
I made jcb with syringe and a rc tractor and more it's fun...
Can you use a mosfet insted of the relais?
yes, but the circuit will be more complicated.

salut, e o statie de lipit simpla, am aratat-o in alte clipuri mai vechi.
Sir can you make ups for computer or how to repair it
You are good
I just stumbled across this video and my thought was that making it a continuous conversion UPS might actually be more efficient than that resistor. This would also completely sidestep the need for faster switching.
Hi. I wanted to test different types of UPS ideas. I will make a continuous conversion UPS in the future, with more features and a bigger LiFePo4 battery.
good
În viitor îți vei cumpara o stație de lipit mai buna ? Poate cu vârfuri t 12 ?
probabil ca da. insa trebuie sa investesc in multe componente si scule, iar venitul din TH-cam este descul de mic. deci mai dureaza.
@@Sorin_DIY ai putea sa îți cumperi noua stație keysger cu vârfuri t 12 sau ai putea sa îți faci tu o stație analogica cu vârfuri t 12.
Cool
Bro will u help me.i made a 12v ups. But when electricity off my router & ups restarts. Will i personally share with u & will u help me to solution it? Please
Hi. You can send me an email with your project, or we can talk on the Patreon chat. I'm guessing that the relay isn't switching fast enough. try to add a load to the relay supply voltage, for example a light bulb, to test if there is any difference.
ciao hello how about a upe for wifi router with lifepo4 or nicd batteries?? Have you built one yet? I think lifepo4 are safer, even nickel cadmium, I'd like to make one bye
Hi. I will make a better UPS soon with a bigger LiFePO4 battery and more features. I'm still waiting for some components.
@@Sorin_DIY ok great, I'd like to build it if you give me a hand, thanks
I like whe he says at 9:24 dummy load😂😂😂
Hey Sorin - first of all thanks a lot, I've learned a lot from your videos. I have a couple questions about your design choices here:
1) Why have two input power sources? Is this for redundancy? It looks to me like the 12v in is the only one that actually triggers battery - so wouldn't a failure of the 19v adapter lead to a failure? I'm not seeing how that would cause the battery to kick in
2) Did you consider using a MOSFET instead of a relay? If so, why not? Trying to understand why one would choose one over the other
Thanks and great videos!
hi. this is an off-line UPS, the 2 chargers power the devices and one of the chargers is used to charge the battery pack. there is no conversion, until the main power is interrupted. then the battery and DC converters power the ont+router. in the future I plan to make an on-line UPS. it will use a single charger and DC converters for multiple outputs. I wanted to make a video with relays.
@@Sorin_DIY got it - thanks for the update. I'm glad you chose to demonstrate the use of a relay. It's been great to see the many examples of small UPS builds to inform my own design choices.
Any other upgrade for faster switching?
I will make a different and better UPS design in the future. now I'm working on other projects.
@@Sorin_DIY Excellent!! Just do it like an ONLINE UPS, with 0ms switching time! BTW, you have a new suscriber!!!

I wanted to make a small UPS. So I searched Google and TH-cam and watched your video.
The UPS I want to make is 24V. Can I do it even if I watch the video and follow it?
Because, I have no knowledge of electricity. But I want to make it. can you help me?
hi. it depends on what current your load needs. if it needs maximum 2A you can use my design. if your load needs more than 2A, you need to remake the design with a bigger battery pack. you can use the same step up converter to increase the voltage of the battery to 24V.
