Thanks for the review, Henrik.
From the graph, it looks like the cells are protected. Is this correct?

No, it is unprotected cells.

I wrote about my lab setup long time ago: https://lygte-info.dk/info/myLabSetup UK.html (A lot of the equipment has been upgraded since) at the bottom of some reviews are also links that may show what setup I do for that review.

Protected cell are still produced, I will be reviewing some soon.

I saw you post, but I do not believe in that type of project, there are too many ebay dealers.

They do still make protected batteries I have some 16340's aw, exposure uk, nitecore not bought batteries now for 2 years or so.

I saw the post too, got shut down but I don't have any desire to buy from eBay or amazon etc... too risky and where I live out in the sticks we don't even have a postman as such. You get a note that says you have to go to the post office 5 klicks away and nobody round here will even entertain sending batteries on the post so I ll be lucky to get em to start with and there's no option to send back.

Curious about these and the vapecell batteries

What software do you use for plotting and PNG'ifying your graphs? Would love to see a walk-thru video of your workstations and routines!

Generally my testing is done with my own software. I have made a piece of software that can interface with all my different brands of test equipment. The result is always stored in CSV files that then goes to charting. My software for charting use a library called "jfreechart".
I have one workstation, everything else is run from cheap laptops, the oldest have been running for about 10 years, the newest is about 1 week old.
