I'm thrilled to introduce one of our most exciting features yet! For the past few weeks, we have begun compiling a massive database of cell data, datasheets, pictures, identification colors, and more. The database can be found here. Each known cell is listed with the manufacturer, model numbers, wrapper and ring colors a side view image, and a link out to a thread specific to each cell. The thread will contain the cell data, a link to the datasheets, and pictures. The idea of having one thread per cell is to facilitate discussions about specific cells, gathering your feedback, best uses for each, etc.

I would like to extend a special "thank you" to Ivan who compiled the initial spreadsheet that these pages were built from. Without this, we wouldn't have nearly the data to start with as we do now. However, that being said, we already added several new cells in the process!

We need your help! There are a lot of cells still without pictures. If you have time, please consider going through your cell bins and taking pictures of those that are missing from here. Please see this thread for information on the requirements and submission process. This is a community-driven project and is only possible with support from the community.

Wow!! You're working to hard, mike. Make sure Pete pays you decently for this work ;)

Great work! Now I have another sub-Forum I have to go through 1-by-1 to clear the "unread" list :p

LOL Sorry. They are working on MyBB 2.0, a ground-up rewrite. It's still another year or so out but hopefully that will fix this annoyance. It does bug me too...

So the idea is to fill in the missing information if we can?
Do we just add it to the thread of the cell and you judge if it goes into the database or not? :)

Please post all updates in this thread. The "database" is an actual database, not just a list of threads. Once I enter the information in the database, I push a button and it regenerates the first post in all of those threads automatically with the updated information :)

That's great.

Any way to get the listing to show capacity and max continuos current in the listing?

I would like to be able to sort them, or do a table lookup when I'm comparing my test results to rated output.

Also, it is a good reference if I were building a new pack and I could filter down to searching for all nominal 2800, 2900, 3000 mah cells.

For the ring, try to get them directly from the top like this

It sound silly but when they're on an angle, it's hard to make them in to this for the listing. They end up looking weird. You don't have to redo them or anything, i'll make them work, just for future cells :) If we already have a database side picture like below it doesn't matter then, any angle works.

Would you please be so nice to put a link for the celldatabase to the forum on-top (like the pack-builder link)?

:)
