To bring the discussion of it is worth buying #certified automotive grade cells over storage grade (#b-grade) cells to an end, once and for all... here is the 200A high power discharge test: EVE LF280K certified cells in comparison to the fake 'Hithium' cells. The best I have vs the worst I have!
So far, we could only test certified cells with a maximum current of 40A and compare them to not certified cells, so called B-grade or storage grade cells.
The results did not show any advantage for the more expensive certified cells, in fact, some of the B-grade cells tested actually better...
Now, some say the certified cells are a lot better with high amp discharge, holding the voltage better, delivering more energy than other cells.
Well, without further to-do, here is the ultimate 200A+ full power discharge test from 100%SOC down to 0%SOC and my final #verdict and thoughts about certified automotive grade batteries...
