The router restarts when the AC voltage is cut. Not good.

[@AmazingCovers376]

Excellent exactly what I was looking for!!

[@flyingfalcon5065]

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.

[@sams1441]

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 ??

[@AbidAli-bo8sv]

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.

[@calder9157]

Very clean and I have designed my own similar system that uses a battery maintainer to keep the battery charged. Only problem with that ups board is during a power outage the relay switch takes a few milliseconds which is just enough time for the router to reset itself and not stay continuously on. I am going to experiment with some larger capacitors once they come in the mail and see if they will be enough to support the short transfer during the relay switch.

[@abhijeetborah4u]

Were you able to maintain the continuous output during switching with the help of capacitors? I was thinking of the same but not sure if it will work. Please let me know if it works and also what size of capacitor did the work.

[@kchandrakant50]

I hope it will work. I have Big Digital clock. it was on cell. I converted it to AC & Battery. At the beginning it was giving me the same problem. The watch was resetting it self in between changeover But as I added the capacitor the problem was solved.

[@KresimirKos]

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.

[@glenraymond379]

yup thats the way to go

[@tophlaw4274]

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)

[@rosekreuze]

@@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.

[@tophlaw4274]

@@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.

[@ramiths7955]

Battery will also be charging when power is there?

[@stanst2755]

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.

[@SanaUllah-gb]

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

[@jayc9003]

It did restart your modem after you cut off the AC power

[@jayc9003]

And i think you interchanged the input of battery and dc adapter charger

[@bjornstevens11]

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.

@@LahisTechLT Thanks for your quick response. We are having a DG set, the problem that I'm facing is whenever there is a power drop, the DG takes few seconds to start and during that time the router restarts. So my requirement is to maximize the usage of direct DC from the Router adapter.

the charging voltage and output voltage is different.

[@nid274]

but if the power goes away the ups battery will be also drained. you will have to implement low voltage cut off also

[@enerbot283]

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)
