DIY - 12V Mini UPS

[@ggppdk]

Really, a quality video, with nice humor. I like that you give instructions for a safer and cleaner result. Plus you give explanations of what you are doing and why. Regardless of building or buying such a mini UPS, the learning process and understanding of the details are valuable for other projects plus as a general knowledge too. Thanks.

[@viralindia8951]

It's not working for me. Before connecting to boost converter, bms output voltage is 11.68 v but as soon as I connect it to boost converter, voltage drops to 0.67 V. And so can't step up the output for 12v. But when I connect boost converter directly to battery output, it works, which is not advisable !!! Please help with this

[@AbdulMominCosTheta]

@@viralindia8951 if your bms output is 11.6v then you can easily use it as 12v. There's no need to use a boost converter. Also, there is a limit to the input voltage for the boost converter. You should check the specification.

[@alois17]

Hi Sorin. Transforming 12 V -> 220 V in a UPS and back 220 V -> 12 V in a router's power supply was always not a good idea to me. I always wanted to get (build) a pure 12 V device. This your video inspired me to do that. Thank you so much for this! Please let me share some of my observations with other people working on such devices like me. 1) You can remove the step up converter from your schematic for most cases. The most of routers, network switches and others have buck converters inside. Usually they reduce voltage to 3.3 V to power the controller. This means you can power devices by even 5 V. Just try. You will be surprised. It looks like manufacturers choose power supplies having just economical reasons while devices can eat from 5 V to even 18 V. 2) Do not worry about back current into the power supply. It is usually less than 2 mA for most power supplies and is safe for them. Thank you again for your videos.

[@kongmeurn38]

Tested and approved as correct!

[@namangupta86]

You must add a diode to the laptop plug from where the adapter is connected to prevent the electricity from going back towards the charger. Not only would the backup of UPS will increase but it would be safer this way.

[@husseinbazzy8294]

my thoughts EXACTLY

[@AtlantaTerry]

What should the diode rating be?

[@mota1maji]

@@AtlantaTerry anything would do a 1n4007 has a rating of about 700v.

[@whitepawrolls]

While your at it could add an inline fuse that would blow before the ones on the battery did as those are harder to get to.

[@thanoswasright626]

Sorry where would the diode be connected?

[@STNG17-]

I also made one for my router but with 3S config. It'll be more practical to do so because you don't have to change the 12V adapter. Good video sir!

[@ChillarPunter]

What step up transformer did you use?

[@jithinramesh3022]

Can you please help by giving a list of the components you use? I am looking into building one but don't know where to get the components online.

[@phylaxxx]

@@jithinramesh3022 The two main places that people source parts for electronics projects are AliExpress and Banggood. They're both Chinese websites which allow you to essentially get the parts for the cheapest price and they usually have global free shipping. I would personally recommend Banggood because I usually get my items within a week and a half when ordering from there vs AliExpress which can take weeks but usually not over a month. I live in New Zealand which means components ordered from these sites get here a bit faster then other parts of the world. As for your question regarding the components that Aji used I might recommend trying a premade board that essentially does everything the BMS in the video does in a single package. Something like this: www.banggood.com/18650-Lithium-Battery-Boost-Module-12V-Charging-UPS-Uninterrupted-Protection-Integrated-Board-With-C-p-1280431.html?rmmds=search&cur_warehouse=CN

[@volodumurkalunyak4651]

@@ChillarPunter with 3S battery and 12V router no step up or step down converters are needed. Router will still work, even when supplied with 9V (3S battery at 1% charge)

[@usamamansoor]

For 3s, the Charging voltage should be greater than 12.6. How did you get this voltage with 12V adapter without using step up convertor?

[@pehristov]

If you want better efficiency, remove the step up converter and add one more battery in series. The router should be able to operate from about 9V up to 14V. Li-ion batteries work 3.5V - 4.2V, which gives you 10.5V - 12.6V power supply.

[@AbidAli-bo8sv]

No, my router works 11v-18v. Although rated at 12v. It doesn't work anything less than 11v. So step up is mandatory. Schottky diodes are also required.

The precision sensor, "between hot/cold."

[@idea-shack]

Very nice, I was designing exactly such a thing for my rooter today and there pops up your video in my recommendations! In my design, I also added a constant current, constant voltage buck converter and set the current limit recommended on the data sheet of the 18650.

[@Sorin_DIY]

hi. if you used a buck converter, then it means you have a bigger battery pack. but the current limit of the buck converter is for the converter output, not the converter input (the battery pack). the input current and output current of the converter differs, depending on the load, converter efficiency and battery pack. there is nothing wrong with it, just don't set a lower output current than your router needs.

[@idea-shack]

I have the battery pack charging FROM the buck converter output, that way when the battery is flat, it charges at constant current (1.65A for my cells... they're 3500mAh so ~0.5C charge) up until the preset voltage is reached for full charge, then it switches to constant voltage mode and then the current drops quickly down. I still use a boost converter on the battery pack to the UPS output to keep the voltage constant as the battery voltage drops. I then use a much higher voltage power supply (24V, ~1A, 25W) because its slightly cheaper and also I get better efficiency stepping down from higher voltages with the buck (>90%). The buck isn't strictly necessary and your design is elegant.

[@zaidhussain5206]

Thank you Sorin for sharing this video, really informative , I have some notes regarding :1-You can use a battery holder for the 18650 you using in case you need to replace the batteries it will more easy rather than doing the soldering job again.2-You can use a protection schottky diode on the input side link SS54 so that the voltage can flow in one direction & not back to the charger in case of utility power outage 3-you can add a switch yo turn of the built in voltage meter to preserve some energy in case of long term power outages.4-what about low battery , should we get any indication when the battery is going low , it the UPS turn it self off in that case ?5-also what about short circuit protection on the output side ? Thank you.

[@Sorin_DIY]

hi. 1- yes you can use a battery holder, but I prefer to solder the cells. I test all the cells before I use them, so very rarely I had problems and need to replace cells. I prefer soldering the cells, because with battery holders there may be an imperfect contact in time between the cell and the holder, also the plastic enclosure needs to be bigger. 2- a diode will block the current from one direction, but it also has a small voltage drop. so the charging voltage will drop below 8V, which is not enough to charge the cells. the charger LED is using only a few mA, it doesn't make any difference in the 6 hours working time of the UPS. it remains like this for now. 3- the voltmeter display is using 17-20 mA, depending on how many LEDs are lit. so yes you can save a little energy by disconnecting it. you can add a capacitor and a microswitch to the voltmeter. when you press the microswitch for 1-2 sec, the capacitor is charged and the voltmeter will remain on for a few sec, enough to read the value. 4- the BMS has over discharge protection at around 2.9V per cell. you can check the UPS voltmeter, when the voltage decreases to under 6V, the cells are almost discharged and it will shortly turn off. I did this test in the video. 5- this step up converter doesn't have short circuit protection, so you can add another fuse on the positive output terminal. or you can use another (bigger) type of step up converter, with short circuit protection included.

[@dleivam]

Brilliant.. I've lost a lot of work due power outages of few seconds, but that's enough for the router to restart and I have to wait until the router reconnects. I definitely try to do something similar as your mini ups. Thanks for the good idea.

[@richd.3270]

I was actually looking for something like this, a portable or mini UPS for use with the Raspberry Pi. Thanks for making this tutorial, Sorin. :)

[@whitehoose]

I've modded this good original design, my fibre router was affected by the high frequency of the boost output. Instead of 2x 18650+boost I found it simpler to use a 3S 20A Li-ion Lithium Battery 18650 Charger PCB BMS. and a standard 3s battery holder. Mod the standard router power lead to tee in the BMS via a 5.5 power jack and fix to the back of a standard 3s 185650 holder (if you need more double up and use 2 cells in parallel x3). 3 cells just about makes a good enough 12v and not having to boost makes life much less complicated, you can use the router's standard psu with bee sting connector to feed the BMS. Because the BMS is teed across the feed and doesn't intercept it - switchover is still instant and bonus is the batteries smooth the PSU output without a capacitor - it means you can disconnect (borrow) the UPS to act as a powerbank without powering down the Router so with the BS on the back of a standard 3 cell 18650 carrier I think it's actually a smaller footprint with a more convenient switchless "always on" connection. Because you tee the UPS to the power feed there is no chance of an accidental break in service win win.

[@lnxpro]

Why not make it out of 3S for 12.6v fully charged and 9v fully discharged? Then you would not need the boost converter. Your fiber router would probably cut off around 10v or less than that.

[@Sorin_DIY]

I wanted to have a very stable 12V output. other people will probably make it for some other devices that may need a stable voltage. this is possible only with a dc converter. it will last longer with a step up converter, because it's using the entire battery capacity. and I wanted it to be small, with 3 cells it needs a bigger plastic enclosure.

[@whatworkedforme]

I learned a lot with this YT video.. esp the BMS system and how it works. Great job. Thanks

[@jayo7799]

Great explanation! Thank you, very easy to understand the operation of 18650 cells on smaller scale. I'm trying something similar before going larger, these things actually are alittle scary and should be treated with caution. One thing I don't understand, does the bms monitor each individual cell ? Thanks great job and that was an important tip selecting good vs bad batteries from the start. 👍👍

[@Sorin_DIY]

hi. yes the BMS monitors the voltage of each cell, that's why it has a lead between the cells. it's the yellow wire in my schematic.

[@JAG9100]

just a tip, if you change the setting on the opus charger to "charge test" it will charge the cells up to 4.2, discharge them, giving you the discharge capacity, then charge them back up. making it easier and quicker to test them multiple times

[@anandsingh8987]

I have couple of questions: 1. Why capicitors and how do you determine the specification? 2. How are you handling the heat disscipitation from buck boost converter as with xl6009, and 8v to 12v with current 0.5 A, it generated good amount of heat.? 3. What is the total capacity and how long this product will support ie. 1 or 2 hours... Very well documented and good video.

[@Sorin_DIY]

hi. capacitors hold a small electrical charge. they are useful, for example, when you connect a big load, the supply voltage may decrease for a second. the capacitor charge will help to keep the voltage stable in that second. the bigger the capacitance, the higher the charge is. so for a bigger load you need a bigger capacitance. for voltage smoothing usually I use capacitors between 1000 - 6300uF, depending on the project. in this project, the step up converter IC only warms up a bit. it can handle up to 85 degrees C and I also added a small heatsink. but for higher current you need a bigger heatsink or a ventilated enclosure. more than that, my ONT is using maximum 270mA, so no problem with the heat. in these conditions it has an autonomy of around 6 hours.

[@alissonneres5067]

If you are always charging the batteries and using the batteries to supply energy to the router, consider lower the charging voltage of the batteries. The batteries can be damaged if always working on maximum voltage. Lowering the voltage can increase the life time of the batteries

You could put a diode for source Adaptor feed back this way it will not light led when adapoter unplugged.

[@Restore2761]

You should add IN4007 diode between dc Jack and battery wire input to block the reverse current flow to adapter

[@volodumurkalunyak4651]

Wrong. It will reduce charging voltage to 7,8V and will blow up very soon. 8,4V 2A charger is used, providing 2A of charge current, 1A diode will blow up. At least 95SQ015 should be used (0,2V drop at 2A and Tj=50°C) - acceptable for dropping 8,6V charger output voltage down to 8,4V. This diode also has around 0,2V drop at 300mA load, 30°C Tj - battery will be kept at around 8,4V as long as charger outputs 8,6V.

[@g3rsiu]

You can put a 1N4001 diode in series with the charging circuit, so that you do not keep your LED on the charger when there is no electric current to supply the charger.

[@zohaibalirajput9348]

You need a charger, not a power supply. Charger: CCCV Power supply: CV only CCCV = constant current / constant voltage. Charger: puts out either a constant current or a constant voltage, depending on the state of charge of the battery Power supply: puts out a given voltage no matter what, cannot be connected to a battery Even if you start from a power supply, you still need a charger between the power supply and the battery, to drop the voltage and limit the current. So, you might as well keep it simple and just use a charger. Note: a "Lab supply" is a CCCV type of power supply, and can be used as a charger.

[@rodstartube]

This is just a battery charger, as batteries are always being drained, either connected to wall adapter or not. The concept of UPS is that batteries will drain only when AC wall adapter doesn't provide energy.

Many 12V router will work normally with 5-8V voltage. Because there is no electronic circuit working with 12V (the processor is probably working at 5V or 3.3V), there is an DC/DC converter at the input. So, the DC/DC converter to 12V just waste energy.

Not bad BUT there are a few flaws with your design, you can’t charge and discharge the 18650 cells at the same time that’s no good for them so you should add a mosfet (relay is too slow won’t work )and diode circuit. 200mA is a very low load, typically a good router is using over 2A so the pack capacity should be higher for most applications I would suggest 3A and a 3S 2P 18650 combination. Finally the boost converter is indeed needed even with a 3S combination so that you don’t exceed the router tolerance even though some routers will work between 9 to 12v but the boost converter should be around 3A for most router applications. I would also use a BMS with thermal sensing for good measure too since u r using recycled 18650s
