Modular PowerWall with removable cells | 18650 project | MakerMan

New version - • Power Modules v2 with ...
--
Here I made a 12v 100Ah Modular Power Wall with removable cells from 18650 cells salvaged from old laptop batteries. I made a these pcbs for the Powerwall, where there are glass fuses to show if any cell is shorted and can be easily serviced. I used my previously made 40cell Charging & Capacity Testing Station to know the capacity of the cells for repacking the cells in to proper battery packs.
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.

nice music, but, if you had explained each step for beginners the video would be 10x better!!

[@springwoodcottage4248]

Fabulous design & build. Lovely how any failed cells can be easily seen by observing the fuses & then easily removed & replaced with a good one. Thank you for sharing!

[@MakerMan]

Glad you liked it. Thanks

[@josephamaral419]

I actually did one of these inspired by this video. Granted, not as clean because I have not ordered the pcbs, nor are they fused, but it's great for modularity and my favorite configuration out of any I've seen so far. I had around 54 cells that weren't being used at all. (Tested though) The video deserves millions of views in my opinion, as does your subscriber count. Great stuff.

[@Electronzap]

Awesome build! Can't believe no factories are making something like that at an affordable price.

[@MakerMan]

Thanks, glad you like it. Stay tuned for more.

[@thesmoothgoat]

Awesome build bro, those custom pcb boards fit so beautifully with the cell holders.👌🏽

[@MakerMan]

Thanks buddy glad you liked it.

[@MikeMcQueen2012]

Brilliant design, thanks!! What amp are the fuses - can you put a link? I bet many people would love to see a design for 24V or 48V, including me :-)

[@maximodejesus5001]

but how many amp can it to support this system

[@FBPrepping]

Dude I am confused, is this battery only 10.8 volts? how is that useful? See the min 7:13 and clarify this please. Thanks for sharing it, is a great battery indeed, and having to avoid spot welding is paramount.

[@ericklein5097]

You said 1200W solar system? Thats 100A at 12V you should be running something like 4AWG or larger for that kind of current....

[@canterburyfour]

Having a difficult time trying to order 15 boards from your link. Please help.

[@ericklein5097]

After measuring the resistance of those leaf spring contacts using cell holders in any kind of large scale system is a big NOPE from me. The PCB is a good idea if someone wanted to do this on a smaller scale to understand how powerwalls work but there is far too much current flowing in a residential system to have cobalt based cells in cheap plastic holders with steel as the interconnect material

[@restfulplace3273]

Things have changed fast. Server rack battery kits are the go now.

[@samdob9832]

hello it would be cool if you could show the detail of the manufacture with the support of a diagram of the electronic connections, even by paying a small sum of money, I would be interested, what do you think? thank you

[@LukVanhauwaert]

Very nice, clean and easy project. I was thinking. Would it be possible to put in every holder on both side 3spotwelded 18650's together? This way you could triple your capacity.

[@Neetje42ever]

That's been done before, so that should work. You may want to make some supports for the batteries though. These holders use a clamping force to keep the batteries in, I'm doubtful they will stay where they are if you put more cells in each slot.

[@jamesjomeldimasaka6342]

what apps did you use for seperating batteries to get best balanced mah?

[@andyjayso4551]

Nice design, please consider to use opposite terminals on each series, the cells discharge should be more equilibrate.

[@FintaruS]

I didn't think off there being a pack builder website.. Thanks :)

[@nathangant7636]

Over time the dynamics of humidity, oxidation and corrosion will affect contacts Silicon dielectric paste on all electrical contacts should be considered for longevity of electrical system.

[@cranebird1467]

It's real great job, but cells will get disbalance soon and become a big problem.

[@muhammadsalau7014]

I love this approach even though too fast for me to fully comprehend. I just wish someone would re-demonstrate it but slowly. Thanks for sharing anyway!

[@MakerMan]

Its very simple, let me know which part you didn't understand.

[@muhammadsalau7014]

You were too fast for me to comprehend, especially from the soldering of the glass fuse to the end. Would it be convenient for you to address this for me in your future updates?

[@MakerMan]

Ok thanks for feedback. Basically fuse are added in the positive side which is parallel contected together.

[@marcelopannunzio4755]

Hello, excellent project. I wanted to ask you if it is possible to make a 48v battery with these pcbs. It would be 14s 24p. Or do we have to develop other pcbs? You could develop these pcb for 100 batteries in parallel ?, or tell me how I should do it. From already thank you very much.

[@healeydave]

It would be good if you gave all the measurement details for your jig assembly as well as you've obviously experimented to get the build just right to fit your hands between the modules etc. Save other re-inventing the wheel and possibly making the same mistakes along the way.

[@akannimoses9760]

How many get kwh ?

[@user-ug9nn]

I give you a like for the idea... but your system can't handle large currents,for charging or use, is more for long term powering

[@abdoleh986]

Just for clarity; each stack is 48 cells connected in parallel (24 on each side) or 1S48p. This would produce 4v 106Ah stack. Then they are connected in three stacks in series to produce 3S48P or 12v 106Ah; did I do the math right?

[@AdventureOutintheWildreness]

have you considered making a similar PCB but using a setup like Joan Olaria and his powerwall? something you can link together in series using the glass fuses? since I don't know how to put my ideas into a real product, maybe you can? I used your gerber files to get 5 4cell discharge boards and 5 8cell charge boards using the TP5100. since I don't have TP5100's I'll rewire it for TP4056's. thanks again for your files, i've been looking for something like this for a couple years now.

[@MakerMan]

Great suggestion.

[@Sekir80]

Wow, what an inefficient use of space for a 1kWh battery! Truly mind boggling.

[@FBPrepping]

Could you build one more compact yet?

[@Sekir80]

@@FBPrepping Yes. He "wastes" the PCB serving as a connector only. Puts cells into holders (if you use holders you could just wire them up). If you use a PCB you can pack the cells in a grid, 10 by 10 would give you roughly 1 kWh, that would be around 20 by 20 by 7-8 cm. You can pack them even tighter if you use honeycomb arrangement instead of grid. This design uses around 50 by 40 by 8 cm of space. Great for show, but nothing more. Edit: watch his v2. Waaaay better!

[@bismarckmasimbi8220]

Thanks for the video, you opened up my mind, I think it the best way of building a power Park or a power wall. I have some questions about the 18650 1 x4 cell holders, Q 1. By using the same type of 18650 cell holders can one build a battery pack or a power wall of 200p 7s? Q 2. What are the total amperage and the total voltage the 18650 1 x 4 cell holders able to handle? Thanks in advance. Best wishes to you, Regards.

[@icopiki1]

Usually these holders are good to be drawn 1A constantly, and 2 amps max.

[@Neetje42ever]

The pcb he's using is for 1s48p packs, which is why he uses 3, so he can get to 12V. You may have to edit his gerber file to add more, or buy 4 for each parallel group and go for a 192p pack.

[@nedzadi]

@@ericklein5097 What if the charging will be done through solar changer directly to 18650 and discharging through UPS? Would that work?

[@ericklein5097]

@@nedzadi As long as you make sure that the charging side of the UPS is not connected and the only connection to the pack is the to the inverter then you should be fine. Hopefully they use two sets of wires for the charging part of the PCB and the inverter but many UPS's do not and it is bundled together and on the same PCB. You could cut the traces on the PCB for the charging portion of the circuit so when the inverter is not in use that energy cannot flow from the charging circuit into the batteries BUT you have to make sure that does not effect the pass through capability of the UPS. So you really need to understand the UPS and having a schematic is the best way to make sure cutting traces is not going to ruin your entire UPS. I guess it would help to have multiple units so you could practice on one and then mess around with it. Pull the plug, plug it back in, pull the plug, plug it back in but make sure the device you have connected is something simple like a fan because you could damage a computer easily doing this if you fucked up the circuit.
