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?
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.
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.
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
@@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.
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.
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 🤔
Hi is a nice aproach to make an DC UPS but I have somes questions to even get better the design 1 the dc-in adaptor-charger is the ones it comes with the router? the voltage is enough to charge the batpack? 2 why is neccesary the boost module, the arrange og the 18650 is not enough 4.2*3=12.6V (real 3.7*3 = 11.1V is for this reason? or even is acting as a fixed 12v out regulator?) 3 in this arrange the BMS is always on chargin the 18650?, when dc-in adaptor is on and the batery is full charged who is really provide the dc ouput ? both dc-in adptor and battery
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.
What's the function of the diodes on this setup? For reverse voltaje? Also, you need to adjust your output voltaje +0.7v, because the diode has 0.7 gate voltaje
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.
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.
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...
thus the battery stops charging when its full and the modem draws power from power adaptor and then when the power cuts that's the time modem uses battery power?
I have done the same connection like yours but my led indicator is always running What to do I have put resistor and diode in + like you have shown What to do?
No i mean in the circuit diagram if we add a direct line from the input power to the output port, bypassing the booster. So that booster is not used when main power is available.
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
Good afternoon, would it work to do this with an adjustable DC-DC power supply module, Boost converter, Step Up XL6009X1 with input IN = 100/35V and OUT = 100/35V?
I have a battery of 5000-5000-5000 mah total 15000 mah 3.7v 18650 number so whichever bms module should i use 10A or 20A and my router adapter is 12v 2.5A does it will work?
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.
@green 3.7v is nominal voltage- full charge voltage is 4.2v . Soo 4.2v x 3 =12.6v This is for Li ion battery for lifpo4 battery its 3.2 nominal and 3.6 full charge voltage.
