Battery spreadsheet for personal use

Hello flashaholics.

Rather than reinvent the wheel, I wonder if anyone has a decent spreadsheet they’d be willing to share to track their own individual cells. Something that tracks by size and probably a number, when charged last, capacity at time (anyone actually measure capacity by amps discharged vs. I put…???), V terminal etc….

I’ve searched here, Ford some posts and links to one workbook, but it was a decade old and I didnt have permission and it’s been a long time since the author has been on here…

Anyway… easy enough to put together with some pivots too, but I’m sure some have put lots of thought into designing one that’s smart…

Cheers.
