Back in 2017, as the community started to grow, we began speculating how many cells have been recycled and put back into use that would have otherwise ended up in landfills, discarded, or melted down for scrap. This led to the creation of the Cell Counter. Since then, we have tracked over 350 individual projects containing a combined total of over 400,000 recycled 18650 cells! And that's only a fraction of the projects out there. The original Cell Counter was intended to track used/recycled cells only and there was quite a bit of disappointment when people couldn't add new or other form-factor cells.
Over the past few months, I have been working to redesign the cell counter and figure out how we can incorporate all the possible variations that exist. This includes a person having multiple projects, a project having multiple cell types, form factors, and conditions, as well as basic sorting, filtering, and statistics reporting. The rewrite has taken a longer than I originally planned, but it's finally ready!
The Cell Counter has been renamed to Projects and is accessible via the link in the top-right navigation area of the forum. All projects from the Cell Counter have been copied over with a default name and cell type entry. You can review and revise any information as needed, as well as create additional projects for any smaller builds you may have, such as portable power, boat/trolling power, UPS conversions, etc. At minimum, please take a moment to give your project a name!, that way they're not all listed as "Unnamed".
The way we are suggesting a project be structured is that each "string" of battery packs be added as a separate entry. For example, in the screenshot below, the person started with 7 battery packs of 80 recycled cells connected in series (7s80p). The average cell capacity in this setup was 2200mAh. A few months later, the person decided to add 7 more packs of 100 new cells connected in series (7s100p) for added storage capacity. This new battery bank had an average cell capacity of 2400mAh. Both strings of battery packs are entered as separate items to provide a more detailed overview of your project as well as more accurate statistics.
You'll notice too that some projects also contain pictures. When you link your project to the corresponding thread in the DIY Battery Project Builds forum, any images you upload to the first post of the thread will automatically be added to your project page. You can edit and update the images in the first post at any time.
The Projects page is still a work-in-progress. We welcome any suggestions you may have and reports of bugs you may find (please). Some of the planned functionality still being developed includes a detailed statistics reporting page, column sorting, and a set of tools for moderators to help manage the data. You can request additional chemistries and formfactors be added to the drop-down lists, but we will only be adding those that are commonly used - not specialized or unique batteries.
