I've also had several requests to consolidate all the data onto one spreadsheet for ease of use. I knew this would be a daunting task - and it took over a week - but finally it's done. ALL test results, of every 21700 test I've done, are now in this one spreadsheet. Besides that, I realized that the DC IR testing I was doing on my big cell load was not super accurate, or repeatable. Also, even though DC is good as it takes into account voltage drop, AC internal resistance is the more universally quoted figure, and the way all manufacturers spec their cells. So I got a professional AC IR tester, and put every cell I've tested on it to create a nice database of cell IR results, that's consistent and comparable. So now in one place, you've got a resource with the real results of IR measurements, capacity, voltage drop, and temp increase for every high-power 21700 cell that has been tested. A pretty cool resource! This video - and the test results - are not sponsored by Lishen, Ampace, EVE, Molicel, or anyone. I paid for all batteries, and all the test equipment, out of my own pocket. Plus investing hundreds of hours of my time into the testing. The results are genuine and unbiased.
