40 Cell 18650 Capacity Testing Station | MakerMan

Here I made a 40 cell Capacity Testing Station for 18650 salvaged from old laptop batteries. knowing the capacity, will allow in repacking the cells in to battery pack and power wall.
I was contacted by JLCPCB a few months ago about their interest in sponsoring some of my projects and providing me with pcbs to speed up my projects. So I decided to restart my 18650 battery pack build project that I've always wanted to do for a ago time but got busy.

In the next video, I will be making a 12volt 100AH battery pack for my solar system.
Many more 18650 related videos to come.

Happy 100th video! This one was really amazing, especially when combined with the previous video. Now I feel like hoarding old batteries and building a massive powerbank out of the good ones. :D

[@MakerMan]

Thanks for your amazing comment. Yes, start salvaging those 18650's

[@alexandresquare]

great project ! just like this you could source an entire E-bike in one swoop ! this is 🔥 !

[@MakerMan]

Thanks 👍

@@MakerMan just received PCB's and modules close to be ready to build but im asking myself wath do you put on P5 6 7 and 8 ?

[@kalifack]

Amazing ! Thank you. Looks simple Enough. Even I could do it xD

[@MakerMan]

Thanks. Yes u can

Awesome project

[@MakerMan]

No you are awesome for saying that!

Nice, I finally found a great video. Going to do this build... once I can afford 40 ZB2L3s.

Thanks buddy.

Thanks pal. I love your videos. You my teacher in 18650.

amazing, nice idea, thanks sir.....

Maker man rockz on

[@MakerMan]

:)

That 12v pack you are designing would it be suitable to being a smaller size for something portable? The Intel NUC for instance can run from 12-19v and it would be great to have a option using around 6 18650 cells to keep a NUC powered up.

[@MakerMan]

Yes that would work nice

[@itsaustraliadayeveryday7234]

Awesome

[@jakesmitte7354]

do you have a full parts list on this

[@RicalIr]

thanks.sir...

Can you help me, make a pcb design, what program do you use ...? could you please tell me. thank you... your idea is very brilliant, I am very impressed with your work

[@outbakjak]

I cannot figure out what components you used in this, even by looking on jlcpcb after uploading your Gerber files. What am I missing? Is there a components lost anywhere in the files?

[@E3CB]

Cool! :)

[@MakerMan]

Thanks

[@Meerschaut87]

Hi, Is there a way to get a parts list and where to buy the parts? Thanks

[@joeldubus2362]

hello, it's me again I just received the jlcpcb plates, why not solder the 4 pins of the module from the back, is it possible? I think it looks easy to do but in reality you have to be very good at soldering everything together, I also think soldering the wires under the zb2l3 board crossing each other makes it very difficult I think it's a design error I have to find another solution Thank you

[@hasger1941]

hello can you provide link for the exact board ?

sir may i know whereto buy that? charging and capacity tester?

[@AverageJoe113]

Is there a BOM file? Can't find it.

[@user-lx1zy4gn8s]

Thank for your sharing. Can I use power supply (Input 220VAC, OUTPUT 5V, 150W). I plan to design 20 cell tester instantly.

[@MakerMan]

Yes, it is more than enough.

[@MarianCobirlie]

i like congratulation !

[@murtazamughal4343]

Sir g 4 cell testr kirnay ka dain gay ap?

[@kodeoka]

After assembling this circuit I have seen that there are failures, one of the resistors has no connection on the PCB, the plates that measure the capacity remain raised, and the voltage input holes are very large and do not enter any type of connector, the positive and negative terminals of the plates are inverted and you have to cross them and that makes the plates not settle well, the PCB is very nice but not very practical

[@MakerMan]

It worked for me fine. Please check your connection again. I tested more than 1000+ cells now and still going.

[@rafael19701000]

I don't understand the position of the fan... the wind goes through the wiring towards the resistors???

[@artycraftygautam6365]

😎😎😎😎

[@cgalan]

Congratulations! Two questions, please: I think this can charge and discharge the batteries... right? and if you use it for charging, what happens when the battery is charged... does it keeps the charge...? thanks

[@chriscars96]

I'm pretty sure he is using a ZB2L3 for the discharging. If so they can not charge battery's only discharge to a set voltage and record the mAh. For charging you would need something like a TP4056.

[@MakerMan]

Yes

[@pradeepdube1398]

Just to add.. If you are serious about the capacity measurement for some huge project, don't go for TP4056. They don't fully charge battery to 4.2V as there is some deviation from module to module. Or use only selected ones which can charge fully up to 4.2V.

[@justtony27]

Hi... Great video .... Can you tell me please what power suply have you use for this project? Thank you :)

[@MakerMan]

PC power supply. Any 5v supply should work.
