Nice work. I ve built many battery power boxes like this. A few tips: 1-Use a USB C to 3S charger. Simple cheap and universal. See Aliexpress 2-To secure batteries, use double sided tape and tie straps instead of hot glue - you dont want those batteries coming loose. Wrap battery in Kapton tape. 3-Do not let the batteries in series touch use spacers or insulation between 4-You do not need the diode on the output 5-Include a small LED battery voltage readout after the switch so you can estimate state of charge of the box. You can add a push button activation to reduce idle current loss.
@@tamer-H Some chargers will allow a backfeed into the charger. If you use a charge board the does not block (like a XL4015 -good choice BTW) or you direct connect like he did and you use for example a DELL laptop charger then you need the diode. I found out on my last build luckily my BMS was current limiting. If the charger is not plugged into AC it can backfeed - so you need to test that case.
This is not "AUTO SWITCHING" power supply. it is constant power supply. Both the Battery & the 12 volt adapter are in parallel without any switching circuit.
My home router ran off a 9 volt DC plug, so I set up an old RV battery to provide 12 V for emergency lighting and radio communications, and a voltage regulator to get 9 volts to run the router. These things are now very easy to do with cheap DC to DC modules.
This is a good idea, tested and its working , he did the right thing , and yes it is acting like dc ups. The only draw back in this system is the dc to dc voltage regulator it does not include a protection at the output from a voltage drop, thus a voltage drop can cause the router to mulfunction.
The diode you use at the output cuts 0.7 volts, the 12 level you set decreases to 11.3, so you should set it to 12.7 so that you have a 12 volt output. Greetings, colleague.
Similarly, the homemade battery pack is supposed to charge to 12.6V but he put a diode between a 12.6V power supply and the BMS, so it will charge to somewhat less. But maybe that'll help the batteries last longer?
I've powered a ADSL/VDSL router using a car battery or a 12V 7200mAh battery (commonly used for alarms or UPS systems). In certain cases, routers don't actually need the full 12V to operate, as they internally step down to 3.3V. This means that in some instances, you can run them on 5V (just make sure you have enough amps - power banks yes, usb ports no). Now just need a UPS for Starlink 🤔
You should have used a charge controller dc-dc board on the input instead of that boost converter on the output (or both). A slight variation in output voltage is usually not a problem and your router will handle that, but your cheap bms will absolutely not handle cell over voltage nor thermal runaway. A bms is NOT a charge controller but a safety device supposed to protect your battery in case of charge controller failure, which your device always have (as there is none).
You got great ideas,d only lacking is that there is no charge indicator. But it'll make do because In my place brownouts are frequents, it's really good to have a backup. Thanks 4 the idea.
look that you had to add 0.6 V to the out to cause of the drop tension of the diode, so it had to be 12,6 V. Good video, very interesting project. Thanks for to have made it
I've used a tp-link m5350 coupled with a smart plug. It keeps the mobile hotspot from overcharging the battery by scheduling when it needs to charge. Online 24/7, it ran for a year.
In this way, the batteries will not last long because they will both charge and discharge. You need to use a relay. When there is city electricity, only the batteries need to be charged. When the city electricity goes out, the relay needs to shut down and feed from the batteries.
Bu şekilde piller hem şarj hem deşarj olacağı için uzun ömürlü olmaz. Role kullanmanız gerekiyor. Şehir elektriği olduğu zamanlarda sadece pillerin şarj olması gerekiyor. Şehir elektriği gittiği zaman role kapanıp pillerden besleme yapması gerekiyor.
This is good use of a boost board to keep the voltage stable when the cells are running low. A nice improvement could be doubling or tripling up the number of cells, still using the same BMS to give a longer running time.
as i studied your circuit theres no auto switching happening here because the battery is running while charging all the time, so it acts like a power bank that plugged into the charger. but i think this is safe as long as the BMS wont fail.
Where's the ats Or simply relay? This is more towards a power bank 😂 It can be called Ats if you divide two power supply lines directly to the device and one path passes through the 12v BMS before it reaches the device Excited about the next content 🎉
Pra mim foi uma ótima ideia, dependendo da queda de energia, roteador com cabo coaxial, funciona mesmo sem energia, desde que o roteador esteja ligado😂
A few dry cells and 2 diodes are much simpler. OR-ing the primary and secondary supplies together to the router through the diodes is a good short-term solution.
You can in a situation 12.6v charger is hard to find although it will not charge fully but it will charge to 12v or 11.9v and the food for the battery health
So if you have an area wide power outage the ISP will be down too, unless they have a backup system. This device would be okay if it's just for an inhouse network or if you can link your router to a cellphone and use the cell phone as your internet connection and link it to the router to keep your inhouse network connected to the internet... Interesting project...
@@homemade_101u should have skipped using diode specially in input. Coz it will drop around 0.6 volt for no reason. Im using the simiar setup but without diode also without boost converter for router. Im using another similar setup with boost converter for my wdNAS(coz here stable voltage is required) but charging with 12 bolt adaptor directly. So each cell will get around 4volt , which is like 80% of the capacity and also the life of battery will be much longer.
Nice video. Not sure if already commented, but maybe either move the LED it output side, or add one there. Seems like knowing there's power at the output, might be more useful than knowing there's power at the input.
For what you need a backup supply for 7h? Its enough if it run few minutes if a fuse blow to give you time to reset the fallen breaker. If the mains fail in your neighbarhood your internet is also down , because the street cabinet is even without power though. The backup batterie in the there has only a litttle capacity to override mains hickups preventing for reboot the system. I recently ask a telecom guy while work on one of the cabinets about the batteries inside. A standard size is 48V 12Ah , its energy for 6 minutes. But the dc UPS is a good idea for other small gadgets, like an radio, emergency lights or music player.
there are some countries, areas, cities, where ADSL still running... you could be facing a blackout and still getting landline tone, so, you could connect the adsl modem and a wifi router to the power backup and get internet, i know this for personal experience
@@jhonkster Yes , of course, those dsl lines are feed from the phone exchange , but they become more and more meaningless while fiber optics spread the countries. Aside from that, this sort of dsl lines are mainly low speed and the customers demand for higer bit rates, for that reason allone the dsl line will die out. Street cabinets needs mains power and no phone company in the wordls will power them with sepate power cables from the exchange building. They cabinets got a meter compartment and powered from the local DNO. Phone exchanges got huge standby batteries , larger ones got back up generators. In this case a UPS system is a helpul device.
This is almost exactly the same as the one Huawei used to bundle with their routers in my country, except it only used 2 cells and they didn't boost the voltage on the output but it worked basically the same way.
Cool. I was going to build something similar but then someone went and made Router Backup UPS for R299 ($16) that lasts for up to 12 hours on my 12V dual band WiFi router, supplies, 5V, 9V and 12 V and can do POE stuff. Oh well. Anyways, I bought a few.
Good idea, however there is room for improvement since there is no charging current limiter on this set up, so the charger will have to have a current limiting feature otherwise it will overheat pretty fast when batteries are low on charge.
You should have used a 12v regulator if the modem is running on 12v. The buck converter isnt a regular. The input voltage will varry is the batteries charge and discharge and the output of buck converter will also vary
Charging voltage 12.6 v for 3S. You are adding a diode at power input , so charger used at input should have 13.2 volts output . Similarly diode at output , boost output adjust must for 12.6 , so that final output is 12v dc .
I have created the same but when connected with power and output. But when I have checked i get that it is actually taking power from battery when the power is available.
You are using the dangerous module with the ci xl6009, because if the voltage drops to 3.5 volts, the output goes to 40 volts and could burn the device connected to it, if in doubt, test

To prevent damage to the router. Because the charging voltage is 12.6 volts. It is advisable to step it down to 12 volts through a Bousit converter.
