Hi Ash, and welcome!
Apologies for the delay, I just finished moving apartments and was unavailable for several days.
Can you tell me or show me pictures of what equipment you have exactly? Do you have a version of the FBRC cell? The MYSTAT software can only control the MYSTAT potentiostat and an Arduino UNO R3 (used for controlling pump speeds). It can't be used with another brand of potentiostat at this time.

Hi Kirk,
Thanks a lot for your time and I hope that the moving process has worked properly for you. After trying and serarching more, I could get the app, and now I can run the cell correctly. But now I do have a new question: Is it possible to order or buy a new cell setup like what is in the website Flow4U Battery Conference (https://fbrc.dev/posts/Flow4U-conference/) ?
Best wishes

@a.rahimzadegan, right now the fastest way to get the latest version of the kit is to build it following the instructions at https://fbrc.codeberg.page/rfb-dev-kit/. We would like to sell them eventually but we're not there yet.

Hi! I work at a technical university, in the mechanical engineering faculty. I'd like to build your prototype based on the documentation. Flow batteries are a new topic for me, but they could be very useful in my field, and this seems like a great way to get to know them better. I also saw your presentation on YouTube. I was about to ask about the peristaltic pump model, but I noticed you’ve just updated the documentation
This forum looks really helpful in case I need any support or clarification. I’ll try to give some feedback if it’s useful to you. -
Welcome @gus and thanks for joining! Please share any feedback no matter how small it might seem. Fresh eyes are really helpful.
The docs are close to being done but not quite there yet! I am going to check over them now, some small things have changed (e.g. gasket thickness is now 0.1 mm).
-
@gus the docs are now more up-to-date in terms of components: https://fbrc.codeberg.page/rfb-dev-kit/index_BOM.html (specific changes here: https://codeberg.org/FBRC/RFB-dev-kit/commit/0c7eae7fe7f829a2d11ad663948377c5c3419191#diff-6bf6300053fa6ad4798859a249550165c9a2ab8b)

@kirk Thank you very much! Are the STL files (under Fabricating Components in the documentation) already up to date? In particular, are the holes in jig.stl compatible with the new pumps?

@gus here is a new jig design. With the latest pumps, we don't need an external motor driver anymore, so the jig could become simpler. Now, the plan is to print an external Arduino case which mounts directly to the jig, reducing print time and the size of the entire jig.
Here are the latest instructions: https://fbrc.codeberg.page/rfb-dev-kit/fabrication.html
This should definitely fit the new pumps.

Hola , somos agricultores en españa, Mallorca, nos apasionan las tecnologÃas que ayuden a ser mas rentables las explotaciones agrÃcolas. Y una de estas tecnologÃa creemos que deberÃa de ser tanto el almacenaje como producción de energÃa limpia y escalable para poder ofrecer a la comunidad, aunque ya hay soluciones comerciales al respecto creemos que soluciones open source son las mas acertadas ya que sirven de contrapeso para no depender totalmente de soluciones "privadas" y en cierta forma hacer de palanca para que halla mas "competencia" en el mercado...... ademas lo open source es el exponente de una colaboración muy estrecha y normalmente apasionada , asà como una forma de encontrar soluciones simples a problemas complejos mediante el ingenio colectivo......
Probablemente en los próximos años soluciones como las baterÃas de flujo sean una gran solución y si las instituciones laboraran una red de baterÃas de este tipo podrÃa satisfacer y dar seguridad al sistema eléctrico "yo lo llamo el Internet de la electricidad"
en fin amigos . saludos de la huerta de pili "finca ecologica" -

@kirk Thank you! I'm starting to 3D print all the components.
Good luck, please let us know how it goes!

¡Hola y bienvenido! I think we share a similar vision
There is another farm that expressed interest in the project in the Dominican Republic: https://vivavistadelmar.wordpress.com/2024/09/24/let-the-power-flow/
One of our main contributors, Daniel, is also based in Spain and can speak Spanish fluently (unlike myself).
It will be a while before we have designed a system robust enough for practical use in a demanding environment like a working farm, but we absolutely plan to get there eventually! See our roadmap for more details: https://fbrc.dev/posts/roadmap-faq-forum/#roadmap

Hi all, I am Alex Quinn, a 6th year Ph.D. candidate experimental researcher in the Brushett Group at MIT.
I've run into your website before, but your presentation at our workshop on flow battery reproducibility inspired me to join this forum. I hope to reproduce some of your efforts. Ideally in the future I can provide feedback and support in items like testing, design, machining, and visibility. I'd be happy to chat more about how I can incrementally contribute as I explore more. Keep up this cool work!
Thanks again Kirk for presenting to us, and for the opportunity to be a part of this community!

@quinnale Hey, thanks for joining Alex and welcome! Let's set up a chat - send us an email at info@fbrc.dev and we can set something up - would be very happy to hear what you're up to and how we can collaborate. We have our regular meetings weekly on Thursdays from 12:00 PM - 1:00 PM EST, but I won't be able to attend tomorrow's unfortunately.

Hi! I just watched your talk at the 2025 Open Hardware Summit. I am a power electronics engineer. If you like any support from that side or electronics in general I can help. I only have very rudimentary knowledge about chemistry, but a strong interest in battery tech. I would like to replicate your work and get a battery up and running at some point.

@lucas welcome! We will be doing more power electronics as the project continues, see some of the discussions and diagrams elsewhere in the forum here for example. We plan to experiment with some of the OSHW power electronics options from OwnTech for our large-format cell/stack: https://www.owntech.io/

Hi, I'm long time a observer of this theme and frustrating about complicated thinking and crashes of developing companies behind. It's mostly a too complicated thinking behind.
I'm happy to find this open source community, open for many users to think about this important technology!Sorry for my not perfect english anytime!
Greetings

Hey everyone, i just read an article about your project on a german tech site and watched your fosdem video and I'm super stoked about this project. I've been interested in energy storage and in particular flow batteries since years and envisioned building one at some point. Unfortunately just by reading academic paper, I couldn't go forward so I gave up. That's why I'm super excited to see that someone did the tough work of creating libre plans for an experimental cell.
I'm an electical and computer science engineer by training but more of a programmer and sysadmin by trade. On top of that I'm a 3d printing enthusiast (sometimes going as far as writing my own albeit simple slicer) with quite some experience with FreeCAD. I'm based in Luxembourg so I hope I can source all the required materials easily.
I'll try to build the experimental cell in the upcoming months if time and motivation lasts and family life allows it to. After and during that process I would love to give you feedback (and maybe improve) on the documentation.
I already miss two sections which I unfortunately cannot supply. 1. Flow battery basics 2. Operation of the flow battery.
In the future I would love to store my excess PV power in my basement using my self built cell :D.
Congrats on this excellent project!
