You need a LI-ION charge controller board placed before the BMS. An economical option is a module board based on the CN3722 chip, which supports an input range between 40 and 12 volts. This way you can use a commercial 24 volt input transformer. The BMS protects the battery against internal overloads and external anomalies, but it alone is not capable of managing the battery charge. For the step down output module, I would choose a variant with an integrated voltmeter, since it has protection against inverted voltage at both ends.
Why do we need a diode right after the 12V input? To prevent ad-dc adapter from being damaged by power from battery? Or when main grid is off to prevent electricity to flow to the adapter and save battery capacity? Thanks!
This might seem like a good idea but in practice there are multiple flaws with this design, first of a BMS isn't supposed to control charging so you risk damaging either the input powersupply or the batteries but connection it straight to the batteries. The batteries will also never be able to reach full charge anyway as they're fully charged at 12.6V which is more than the 12V input not even accounting for the voltage drop across the diode. At best the battery might get charged to 50%. Finally the out put is connected to a step-down module which in all fairness does make sense for the router in the video, but the vast majority of routers are powered by 12V which this setup can't handle and the comments are full of people not realizing this (you'd need a boost converter/step-up regulator for this). Please do not try this at home, it lacks safety and won't work for most applications there are other resources on how to do this in a much more appropriate way available online.
Die Anwendung ist echt Verständlich gemacht, aber was mir nicht Verständlich ist, der Ausgang des BMS zum wird gleiszeitig als Ladeleitung für die Akkus genutzt. wird das evtl. über die schalt Dioden möglich gemacht. Mit positiver Ladung zustand vom Netzteil
A question to those BMSes: Do they have a smart charging circuit or do we have to take care of maximum 3*4.2V powersupply (maybe thats why the diodes exist) as well as current limiting? An empty cell would suck up all the current until the Voltage collapses except a charge circuit takes care of CC and CV. If overvoltage, does the BMS completly cut of the battery or just the charging circuit? (So that the router is still supplied by battery xor powersupply)
I’m sure this was posted with the best intentions and although it might work it’s not really ideal. Few things to note: If using a 3S battery, the battery voltage will discharge from 12.6V to about 9V. So it is not supplying the constant 12V as the factory power supply does. Lithium ion batteries need to be charged with some sort of constant current. I’m not quite sure how this circuit achieves this. I’d say the concept is there but lacking attention to the finer details.

As far as I know, this 20A board doesn't have a balancing IC... the 40a and 60a versions already have a balancing IC. Is it true? Please tell me if this version 20a board already has a balancing IC
What if you just skip this module and use the battery connected to the power supply. Current will be drown from the power supply, the battery will be fully loaded. When there is the outage battery will be used. Whta is the advantage of this module? Voltage regulator can be used to produce stable 12V. My router works fine for input voltage 9-24 so it has the regulator build-in.
Se colleghi direttamente le batterie al litio ad un alimentatore senza limitazione di corrente oppure di tensione la corrente potrebbe diventare eccessiva e tale da danneggiare le batterie o addirittura farle esplodere.
thanks for the awesome video bro .. just 1 question on diode .. will the diode get heat up .. could u please check once? is there any alternative for diode?
My modem input volt is 9v 1a only. BMS will provide 12V 10A, So I need to ensure that I am giving the correct voltage and ampere to work my modem without any problem. To reduce the volt and the current I am using a DC-DC Buck module (LM2596).
Hey, is there any diode better than 1N4001 which has lower voltage drop when i connect to a 12v supply the diode will be drop 12v to 11v i think which is not enough to a bms board so can u suggest a better diode or any alternate component which will be better
i am having 12v bike battery then there is no need of use BMS am i right. once the battery is full means the current will automaticaly cutoff and the current flow directly to the wifi router which component will handle this job.
If I add 3 more battery and make it parale (to keep voltage at 12v and increase battery cappacity) to extends Router backup time, should I change BMS module? What BMS module type/specification you recommend? Thanks
what is the use of buck-boost converter here? Why can't there just be a battery, which is being charged by input dc connector while the dc connector still provide power to the load and when power goes off, the battery will provide the power to the load? Anyone please reply.
I used buck-boost converter because I need 9v only. Usage of BMS is to protect the battery for overvoltage and low voltage. It will charge the battery too, once the battery is full the power supply will be cut to the battery, and it will go to output directly.
Very nice and helpful project and I am about to do it but I want to ask you. When I plug it into power socket 220V and I have the power on the UPS does it take power from the battery or the socket and if I keep using it like that is there a danger of burning it ? Thanks
That's why we are using BMS. When the battery is full, BMS will stop charging the battery and the current from AC will directly go to the output. No worry everyday I am using it.

The BMS discontinue the current flow as soon as hits below 11.5volts on the batteries. I have 6 18650 li_ion batteries connected to a 10A BMS 3S. The backup time is only a few minutes on a 12v 1amp internet modem. Please advise on how to increase the backup time. thank you
same problem mere sath bhi ho rahi mera router 12v 1.5A hy but is ka solution mil gaya mujhy pehle me khud try karta hu i will let you know if i succeeded.
if we don't change the plug , there will be no direct connection between the router and the main current. the batteries will give the current 24/7 , which is not a good idea
The router will run on battery 24/7 but the problem is when there is a power cut + the battery is also dry in a few min, you will not able to use the internet. It will create unwanted tension. The main purpose of this module is to use the internet without any interruption even powercut.
Is it possible to add more baterries so they provide the 12v needed, perhaps using a different charge controller? Does the booster itself consume any current to work?
100% BMS will charge the battery. I am using this module every day since I made it. I will plug in a 12v 1a power adapter every day Morning 9am to 9pm. It will work up to 7 hrs in case of power failure.
@@MrAKsTime thanks! I am going to build the same thing, and I had that question before. I thought I need a voltage DC-DC step up to make it to at least 13V. Another question: can we just plug in the AC power supply non-stop, so we don't need to unplug it when the battery is full? The BMS will regulate the charging, right?
Or you can use LM7812 regulator to get constant output voltage, but you need more than 12v output to use this. Or try with xl6009 first, and monitor the battery life. Then decide.
Can I leave the power adaptor switched on in the input jack while the ups is in use? Will it overcharge the batteries or will my power consumption goes up?
Yes, you can leave it. BMS will stop the current to the battery once the battery is full. So the current from the power supply will directly go for output. The boost or Buck module will control the output. I am switching on the AC-DC power supply at 9am and I will switch off it at 9pm only. I will get a continuous connection even power cut.
ive seen a lot of videos they use a relay but it still has a flicker of about .33 seconds. so far this is the good built connect the AC to the battery and let the BMS do the work.. no downtime even if AC fluctuates
Salam Sir, I've watched your video and made same power bank accordingly to the wiring but I'm facing issue. Router specs : 12V 1Amps UPS made 12V but I've used XL6009 as i think that it should give constant output voltages even input fluctuates o/p remains same. Now my issue, When my power bank is fully discharged and when the power from adopter is again arrived my router doesn't turn on properly as its power led blinks continuously and remain like that (Not turning on my router) until I turn my router off for once and turn it back on. what could be the issue. One more thing what is the purpose of diode on the output as 1N4007 has a voltage drop of almost 1V which is already drooping on the I/P also while charging the battery and supplying the router at the same time which leads to lower voltages 11v which I think could be issue as there are two loads one is battery that's completely drained out it needs to be charged and the other is router which also need voltages of its requirement ( but that router voltages can be maintained through Step up converter as it will give constant O/P Voltages but not current). Could it be possible that I try same voltage higher amps adapter so that as it need initial torque when it's charging the battery and the router at the same time as my charger that comes with the router is of 12v & 1Amps it's designed accordingly to the router. What are your thoughts on this kindly guide me through this problem thanks. Regards, Usama Zaib
@@MrAKsTime That diode option I've tried already it doesn't work I'll check that lm 7812 option and one more question that you've missed is that the reason of diode on the output.
@@MrAKsTime But according to the datasheet of XL 6009 it says that it's Min input can be i think 3/5 V there should not be any issues for this module to boost those voltages as batteries are giving 12 V even when it's discharged that bms property is that at almost 6-7 V it cut off so 6-7 V it should be no issue for this module to boost those voltages as it is made for this purpose.
@@MrAKsTime The XL6009 DC-DC Buck Boost Converter Module has an input voltage range of 3V to 32V, and an output voltage range of 5V to 35V. I've checked it through the internet.
Sir I have a question. Can i take two output of 12 volt from the single LM2596 for my two routers rated 12v 1 amp respectively? Waiting for your answer

@@MrAKsTime You need xl4015 charge module to limit charging current. BMS only goes into protect at 20A (and will not allow charge until disconnected). Router power adapter is only rated 1 or 2A, Will overcurrent when li-ion battery at 9.6V is connected
@@Android-ng1wn you are absolutely right , charging should be limited to 2A, otherwise battery will get hot and even can burst, if the input supply has so.much power to feed, normal router adaptor will nit charge completely discharged cells

So the BCM Balanced 12v, must use the charge adapter lower 12,5v to charge, if higher ( ex: 13v) BCM Balanced will cut-off cause UPS doesn't work?
Switch should be on the input of buck converter. This should reduce battery drain when not in use.

The BMS discontinue the current flow as soon as hits below 11.5volts on the batteries. I have 6 18650 li_ion batteries connected to a 10A BMS 3S. The backup time is only a few minutes on a 12v 1amp internet modem. Please advise on how to increase the backup time. thank you
same problem mere sath bhi ho rahi mera router 12v 1.5A hy
but is ka solution mil gaya mujhy pehle me khud try karta hu i will let you know if i succeeded.
1 solution work kar chuka mere pas lekin 1 or solution try karta hu agr us me kamyab raha vo ziyada behtar
Did you use a 1n7004 diode to block reverse current in both input and output?
@@MrAKsTime yes, I have.
@@anisabibi5487 okay... Send me the pictures to t.me/mrakstime I will check it...
What about the voltage drop due to Diod?
Good evening, I can use x 4 batteries 2600 mah or more. But charging them with a solar panel?
I have used buck booster pcb XL 6009. But the BMS output voltage is dropping to 4V when the XL 6009 pcb is connected. What to do ?
please reply
Hi, whata the difference between 3s 20A or 3s 10A. How does this matter on BMS
3s 10A will support up-to 10ampere current, same as 20A.
Please is it available 4v 18650 battery? I got 3.7v only.Thanks & Regards..
Yes, 18650 battery BMS is available for 4v. and you need to use XL6009 to step up the output voltage as per your router.
if we don't change the plug , there will be no direct connection between the router and the main current. the batteries will give the current 24/7 , which is not a good idea
The router will run on battery 24/7 but the problem is when there is a power cut + the battery is also dry in a few min, you will not able to use the internet. It will create unwanted tension.
The main purpose of this module is to use the internet without any interruption even powercut.
@@MrAKsTime 😂
Is it possible to add more baterries so they provide the 12v needed, perhaps using a different charge controller? Does the booster itself consume any current to work?
If you increase the battery, you will get more backup. you can add and the boost module will not consume much current.
Is bms m Charging ho rhi ki nahi y kaise pta chlega ????
I have one question: so the BMS get 12v input (or 11.4 volt because the diode takes 0.6v) , can the BMS charge 12.6V to the battery?
100% BMS will charge the battery. I am using this module every day since I made it. I will plug in a 12v 1a power adapter every day Morning 9am to 9pm. It will work up to 7 hrs in case of power failure.
@@MrAKsTime thanks! I am going to build the same thing, and I had that question before. I thought I need a voltage DC-DC step up to make it to at least 13V. Another question: can we just plug in the AC power supply non-stop, so we don't need to unplug it when the battery is full? The BMS will regulate the charging, right?
@@gunsts BMS will stop charging once the battery is full. So no issues.
@@MrAKsTime BMS will not charge the battery, it needs 12.6v
@@sergLV remove the diode.
I use 1.2kw inverter with 200ah tubular battery. So I don't care about power cut.
XL6009 will reduce the back-up time. I hope we can avoid using it. What do you think. What will happed if we dont use XL6009. Is it neccessary ?
Or you can use LM7812 regulator to get constant output voltage, but you need more than 12v output to use this. Or try with xl6009 first, and monitor the battery life. Then decide.
@@MrAKsTime We cannot use LM7812 as we do not have more input voltage. The Nokia adapter hardly give 12.08V.
Can I leave the power adaptor switched on in the input jack while the ups is in use? Will it overcharge the batteries or will my power consumption goes up?
Yes, you can leave it. BMS will stop the current to the battery once the battery is full. So the current from the power supply will directly go for output. The boost or Buck module will control the output.
I am switching on the AC-DC power supply at 9am and I will switch off it at 9pm only. I will get a continuous connection even power cut.
if you use this setup majority of the time with wall power like a router, theres no issue with overcharging the battery?
BMS will protect the battery. It will stop the power supply once the battery is full.
@@MrAKsTime can i use it on a 24v setup. lets say instead of using 3S bms ill use diffrent bms for example 4s so it will have a long run time
ive seen a lot of videos they use a relay but it still has a flicker of about .33 seconds. so far this is the good built connect the AC to the battery and let the BMS do the work.. no downtime even if AC fluctuates
@@jhazbandola6808, yes, you can. Ensure the output voltage and ampere are correct as per the modem/router input voltage.
@@MrAKsTime how to check amp ?
Salam Sir,
I've watched your video and made same power bank accordingly to the wiring but I'm facing issue.
Router specs : 12V 1Amps
UPS made 12V but I've used XL6009 as i think that it should give constant output voltages even input fluctuates o/p remains same.
Now my issue,
When my power bank is fully discharged and when the power from adopter is again arrived my router doesn't turn on properly as its power led blinks continuously and remain like that (Not turning on my router) until I turn my router off for once and turn it back on. what could be the issue.
One more thing what is the purpose of diode on the output as 1N4007 has a voltage drop of almost 1V which is already drooping on the I/P also while charging the battery and supplying the router at the same time which leads to lower voltages 11v which I think could be issue as there are two loads one is battery that's completely drained out it needs to be charged and the other is router which also need voltages of its requirement ( but that router voltages can be maintained through Step up converter as it will give constant O/P Voltages but not current).
Could it be possible that I try same voltage higher amps adapter so that as it need initial torque when it's charging the battery and the router at the same time as my charger that comes with the router is of 12v & 1Amps it's designed accordingly to the router.
What are your thoughts on this kindly guide me through this problem thanks.
Regards,
Usama Zaib
You just remove the 1N4007 Diode and try. If the problem is continuing, use LM7812 input from XL6009 and increase the voltage more than 13v.
@@MrAKsTime That diode option I've tried already it doesn't work I'll check that lm 7812 option and one more question that you've missed is that the reason of diode on the output.
@@MrAKsTime But according to the datasheet of XL 6009 it says that it's Min input can be i think 3/5 V there should not be any issues for this module to boost those voltages as batteries are giving 12 V even when it's discharged that bms property is that at almost 6-7 V it cut off so 6-7 V it should be no issue for this module to boost those voltages as it is made for this purpose.
@@MrAKsTime The XL6009 DC-DC Buck Boost Converter Module has an input voltage range of 3V to 32V, and an output voltage range of 5V to 35V.
I've checked it through the internet.
Sir 12v battery can charge 12v Router adapter.. Its very ezzz i want to make 1 ups for my router and onu

Sir I have a question. Can i take two output of 12 volt from the single LM2596 for my two routers rated 12v 1 amp respectively? Waiting for your answer
Take two output and connect your router with one output and simultaneously check the 2nd output with multimeter first then connect with router.

Apakah bisa bms 2 s dicharger dengan charger hp 5 volt ditambah step up menjadi 8.4 volt,caranya bagaimana?
You need 9v charger to charge this 2s 18650 BMS and or you need step-up booster module XL6009 to increase the voltage from 5v to 9v.
I also make a video about this ❤
BMS has input current limit? Otherwise overcurrent 12V adapter when power returns no?
12v is a BMS input voltage and it has over-voltage protection. so no worry...
@@MrAKsTime You need xl4015 charge module to limit charging current.
BMS only goes into protect at 20A (and will not allow charge until disconnected).
Router power adapter is only rated 1 or 2A, Will overcurrent when li-ion battery at 9.6V is connected
@@Android-ng1wn you are absolutely right , charging should be limited to 2A, otherwise battery will get hot and even can burst, if the input supply has so.much power to feed, normal router adaptor will nit charge completely discharged cells
excellent
Sir bms ke aagay step up module laga raha hun to volt 0 ho ja raha hy aisa kiun ho raha hy
4ell is not working for 3s! why?
Because it is 3cell BMS (3s), use 4cell BMS (4s)

Heyy can i connect more battery in this same module ?
yes.
@@MrAKsTime i have to ask something more . Can i use the dish tv adapter as a phone charger?
@@Rahulsaini-tj9du if it is 5v up to 3a means you can use that.
@@MrAKsTime is there any module that can convert in to 5v?
@@Rahulsaini-tj9du Yes, search DC to DC 6-24V to 5V converter in google. you will get module with a USB female port.
dude, that battery is not fully charged. When you put a diode, the voltage drops. Not enough to charge the batteries.
Okay, just increase the diode value from 1amp to 2A or 3A diode.
@@MrAKsTime it doesn't matter. input voltage drops to 11.40. The batteries are not fully charged, any solution?
@@kevel3472 Using Diode is to avoid the reverse current. you can use it without a diode.
@@MrAKsTimediode part number for 1.5amps and 2amps please? Thank you
How to charge it? The router charger is 9v
You need a 12v charger to charge the battery. LM2596 will give you the 9v output.
