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.
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.
@@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.
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.
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
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 ?
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.
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).
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
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.
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.
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!!
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
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?
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?
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
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!
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. ❤️
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.

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.
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.

The heatsink already have conductive tape.
I will recommend to use cooling paste.
Great project
What will be the charging module if using battery in 3S configurations?
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?
@Open Green Energy I have xl4015 5A with only voltage adjuster. I cannot adjust the current. Will it work?
