DIY - 15000mAh Power Bank - With Salvaged Batteries (gets charged with 3A)

Hello and welcome back! In this episode I will show you how to make a 15000mAh power bank, which is very small for its capacity and it can be charged 3 times faster than regular power banks.
Instead of XL6009 I suggest you use the MT3608 boost converter, it's much stable when the cells get low on power.

[@elisnovat3955]

In stores most of the power banks use large single cell type LiPo batteries or something similar like a huge phone battery. Basically it's just big and flat. I like the idea of adding in your own cells when the old ones wear out. Which you can do if you have a soldering iron, you need a pretty powerful soldering iron to solder things to the battery terminals though, as they suck the heat away fast into the battery and that heat can easily warp plates and damage the internal battery. So you need a soldiering iron tip that is incredibly hot so you can do the job fast. You probably need a soldering iron tip of like 400 degrees Celsius at least to do this. I wish they just made a cool empty battery bank that you could add say 8-16 cells to. And you don't have to solder them in, instead being held in tightly with high quality springs. And it would have USB output and 12v output, as well as input charge via USB or AC adaptor charging for faster charging. This would be really cool, because people could easily turn a bunch of laptop batteries very easily into a useful battery in their home. I mean just 16 average laptop cells combined will give you at least a 35000 mAh battery. Maybe they make something like this already, I haven't looked. But I would rather something with useful functions and easy to put together and replace batteries, instead of something I have to solder together while worrying about damaging the cells and needing an expensive high temperature soldering iron etc and then having a pain to replace them.

This diy power bank is very good, with some updates can get better, I'll do one, for sure (if I can get money because the situation of Brazil is a bit difficult here).

[@t1d100]

This is a nice build. Thank you for your efforts to share with us. Would there be any problem taking this unit on a plane, because it is DIY? For lowering the profile of a toggle switch, another option is to trim down its lever. If the lever is metal, a hacksaw may be needed for cutting and a file for easing the edges. Remember to seal the entire device with painter's (blue) tape, before starting to cut, to keep the metal shavings out of the switch. I would also like to see a DIY battery bank project that uses a DIY battery management circuit. I just have a problem trusting the cheap Ebay modules. And, learning about the circuit and building it is way more fun, IMO, even if it costs a little more.

[@Sorin_DIY]

hi. I don't think they will let you take it on a plane, because it's DIY, it's pretty big and it has a lot of lithium cells. probably if you build a smaller version it will be ok.

[@Tore_Lund]

Why do you charge them in groups of 3? You can parallel the 3 TP5060 for 3A charging. What will happen if you do it like this, is that, which you also mentions in the video, is that the TP5060 modules are slightly different in end charge voltage, so you battery pairs will be at different voltages, somewhere between 4.21V and 4.11V, so when you flip the switch and switch your batteries in paralel, some current will run between the batteries, possibly not enough to blow the fuses, but you are wasting power and adding resistors as your solution is also wasting power. Just parallel all 6 cells and all 3 chargers and you'll be fine.

[@Sorin_DIY]

hi. each tp4056 charging module has better control over the charging process, if it charges only 2 cells in parallel. every electronic component has an acceptable error, usually of 1%. so if you connect all 6 cells and 3 charging modules in parallel, the charging modules will not read the exactly same voltage, and the charging current will be slightly different. so they cannot be coordinated to charge exactly the same way. the cells voltage may fluctuate because of this, while charging, this is not good for the cells. in my configuration, each pair of cells is charged as fast as possible (depending on the 5V USB charger) without any interference between them. and when you fully charge them, all the cells will have the same voltage ~4.2V. there will probably be a difference of only a few mV between them. the power wasted through the resistors is insignificant. the power wasted from the self discharge rate of these old salvaged cells will be higher, than the power wasted to keep the cells from getting unbalanced with the help of the resistors.

[@ZillionPrey]

Even if i like diy projects since I'm a tinkerer myself I'd stay with my anker powerbank which supports quick charge and also up to 3A per port.

[@HobkinBoi]

There isn't anything wrong with that. Sometimes you're better off buying than making, or in some cases, vice versa.

[@PunakiviAddikti]

You could have bought a power bank module, they are available online and have all the balance charge, over discharge, overcurrent and boost features, as well as the built in meter.

[@TaylorSoloaiJR]

I thought about this too but I don't see any that can charge the batteries fast enough, most of them maximum charge current is 1A which is okay if you have 1-2 batteries. Unless you have a link to one that can charge up to 2A because I am trying to build one that has 6 18650s in parallel. Been looking but no luck.

5:04 I'm curious in your schematic why you connected the negative wire from the output of the charging module to to negative output of the Step Up Voltage converter. I thought it should be connected to the negative input of the step up module.

those modules have just one common negative, in- and out- are bridged on the PCB

Hii bro i made this power bank but i have one issue.. When the cells indictor on 40% battery the xl6009 step module only give 10 to 90ma not giving 1amp please help me..

[@Sorin_DIY]

the xl6009 needs a minimum input voltage of 3V. when the battery discharges below 3.1V, the step up converter will not work correctly. that's why I linked a MT3608 boost converter in the video description: s.click.aliexpress.com/e/_9wol94 it works with a minimum input voltage of 2V.

[@SpaceCatCat]

4:42 This is not correct because USB can only transfer 2.5 amps. You must have 3 USB ports, which must be powered at the same time.

[@LPNikolaj]

you could also just use a different connector to supply those 5V... think ATX PSU 5V Rail for example

[@lahmyaj]

[@Роман-ч3о9д]

[@takruiz289]

Nice project! The most informative and safety that i found. One question though. How did you protect the 18650 from the modules from each other? In case 1 of them over heats

[@Sorin_DIY]

hi. I used sticky foam tape as spacer between the charging modules and the cells. the charging modules should not overheat, only if they are damaged. if there is too much current, the fuses will protect the cells.

[@jopalzm1]

Why the resistors connecting the + of the batteries? And also I don't know, why he use XL6009 DC DC Converter? It cannot be from TP4056 module direct to Charging USB?

[@bens4446]

I've built two of these now using salvaged laptop batteries. Thanks for the instructions. One question: when I charge my phone with these it only draws about 0.5A. In the video it looks like you easily get upwards of 1.5A when charging your phone. Any idea why I am not getting that? My phone draws 1.2A from the wall socket.

[@Sorin_DIY]

Hi. Did you bridged the 2 data pins on the USB port?

[@Sorin_DIY]

you can use a 3pdt switch with 2 tp4056 modules and 6 cells. you connect the cells in 2 groups of 3 parallel cells. each group will be connected to one tp4056 module.

[@nikdonic]

it has a very nice look and you used space very efficiently but I didn't see current while you were charging your phone, most phones will charge only with 1A or even 500mA when they can't detect any identification for how much current they can draw from the USB port you can use a simple resistor between USB data pins if you know which standard is your phone using and it can draw full current but it may not work for all phones there are few simple IC like TPS2511 which can communicate with a connected device and set the maximum possible current

[@Sorin_DIY]

hi. I've shorted the data pins and it's charging my phones with max 1.7A. Apple devices and a few more need those resistors on the data pins.
