A proper way to make a router ups is using 12xx series ICs. It will properly cut off power due to discharging. Otherwise the router keeps restarting. I've tried a few setups and found this solution as the best way. Thank you.
Very great watching and it's nicely done. However in market for Rs.999 only we get handy UPS for wifi it includes battery inside gives 4 hr backup during power cuts
That automatic switching module (#0:52) just switch the connection. It can not charge the battery. Btw this video makes me realize that it is better to use 2 power supplies (1 for the battery, another for the router, or other things) in this type of circuit. Thank you for this video. 😇
Why did you use XL4015 5A Power Supply Step Down Module when the Power-OFF Protection Module Automatic Switching Module is capable of charging the battery?
bms and YX850 or bms and XH-M350 you need more circuits.. his setup seams for complete isolation its an ok set up if you don't mind charging separately the video used YX X804 not YX850 or XH-M350
I have made a similar setup for my router, for daytime use case. I have two power sources, one js adapter & second is solar panel (18v 8A). I used a buck converter LM2596, a 12v relay and a Diode for reverse current protection. LM2596 for solar panel to step down from 18v to 12.8v. This works great. When adapter gives power, it is default power to the router. When adapter is off (electricity off) then auto switch to solar. However still there's a delay as this video shows.
Can u explain the reason why you used a step down module here ?? does Automatic switching modules itself not charging the battery if it is on main current ??
I'm making similar box for my 9V router, but will use DC step-up for charging 12V battery from 9V power supply instead of Power-OFF Protection Module. That way 12V battery will be always automatically charged and ready.
be careful. you will want to use a protection circuit as to not overcharge the battery (or just use an off-the-shelf smart lead acid battery charger)... overheated lead acid batteries tend to boil internally & self-destruct (well not explode-explode but their case cracks & the acid goes everywhere)
@@tophlaw4274 not also ideal to always charge the lithuim cells to full. i also have a 8.4v ups pack boosted to 12v. after a few months one of the cell died. the method used in this video is much safer for batteries either lead acid or li-ion, you can swap batteries when needed. that way you can stack up some salvaged batteries and make a 2s or 3s with a parallel of 3 or more. the only issue is the switching of the relay has a delay of about 1 second. an electrolytic capacitor might make the handover seemless.
@@rosekreuze I never mentioned anything about charging to full... just that it's a bad idea to keep charging batteries constantly. Lithium batteries are a different story charge-wise as heat becomes a major factor (moreso than keeping them always topped off)... which the LahisTech's approach will actually do. Also, lithium batteries require a proper charge voltage that smart charging circuits will provide (including automatic cutoff to prevent overcharging as well as overdraining when it's unplugged) definitely a must have if you're planning to use LiPo/LiIon batteries.
Just make battery voltage to adapter voltage. and put it parallel to chager output..thts all. Normally routers work 7-12.5 v. That means a parallel leadacid battery can give 1-2 -3-or 4 hr of uninterrupted power. Im using like this, now its 2 year 🎉 no problem.
Very interesting video, thank you! Does this device charge the battery? Is it possible to make it not charge the battery? I need without charging. And the second question, when the power goes out and switches to battery power, does the router reboot or continue to work? That is, does the switching happen instantly or with a slight delay?
this is just ok for DIY experiment... but - no recharging - no low voltage cut off (not sure) - costs of components including battery will be much higher than commercial wifi UPS with included battery
you need the yx850 that also charges the battery. its actually the same board but with a big diode in-line of both the positive input. or you can just add a diode yourself 😂
Great neatly made ! But i have question Is it the zero lag switch as i can see a blink when u turn off the ac power It would be even better if rechargeable li Ion cells used instead of huge battery pack . And also we can reduce the DC connector points
@@omshivtiwari a large enough capacitor could keep the power going during the brief outage during the switchover though it depends on how much current your router draws
The project is very good. What modification should I do if I want to have two 12 V outputs? one for the router of 1.5 A and another of 1 A for the fiber optic terminal. I appreciate any help.
nice idea. the circuit it got also does the same when it switches from main to battery the is blink witch is enought to make router reboot but when it switches from battery to mains its ok. also another drawback is that the circuit doesn't charge the battery
Hi Thanks for the video . Please let me know whether this unit will charge the 12V Battery, when power supply in on. Or we need to change the battery separately
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.
Yep, I like the idea but the way its now made is just totally worthless in my opinion. 1. You don't have the battery charged at all times/ you don't know how full it is 2. There is no protection for the battery to stop when battery voltage is getting too low 3. No (super)capacitors are used to let the modem/ap stay on during the switch. 4 (ish). Battery isn't built in.

3x 18500 cells would be more than enough for this project ! I have built mine with 3x 2800 mah cells and it powers the router for 12 hours. And its waaay more compact
On the YX850 Power Failure Automatic Switching Standby Battery Lithium Battery Module, the DC terminal has power, it is connected to the battery to charge How can the battery be charge without a charger and how they know what the voltage to charge the battery?
This is not a router UPS as the power will be cut-off during the switch over from mains to battery source (a relay takes a too long time to switch). The only design that works for true uninterruptible power is a design where the power output is always powered from the battery source (the battery being charged with a control circuit when mains power is available)
router resets every power-cut when relay swithes to battery, it can be seen on the video, so you will lost you internet conection for router boot time can we improve the circuite adding capacitor that will handle power drops?
If this board also delays the switch causing device to restart, then Switching can be done using a 12v relay and a Diode. No need for this complete module.
Can we manage the output valtage when at a time the input valtage is increase and decrease occurred. Beside that what is the price and where available the production
No, the max Amp output on the internal electronics is 1amp. As we add more wifi users on your network, the current draw increases and the unit tries to restart. I have experienced this in this very setup.
It seemed like a failed project. The adaptor led should be off and switch to battery led after power failure, and when power resume the battery led off and adaptor led on.
Please i have some question which i am looking for anyone who could point me in a right direction,i am trying to know something about an inverter/solar electricity generating system for a home or organization,i was wondering if there is some kinda software or device which can be inserted into the inverter/solar electricity generating system,which will make me have some kind of automated central control system on pc or phone to switch the device off from any location and and wouldnt be able to come on if turned on from the generator itself, but can only switch it back on from my device or terminal.

Right
If your device requires 1A current, use a 2A adapter, this will charge the battery as well as keep the device running.
