We all have heard the Tesla 2170s are different than the standard Panasonic (Sanyo) cells so I’m trying to learn exactly how different. I’ve got a background in EV power systems and been curious about these cells and found some time so I’m currently running tests on a few 2170’s to characterize these batteries. I’ve discovered some things with used salvaged cells I grabbed off ebay and would like to cross reference these findings with new cells and only have limited-time access to the equipment I’m using. I haven’t found any source of these cells and hope someone here can help.
I’m looking for a source for a few (hoping for 4) cells to test. I’m under a time crunch because I only have access to the lab and the equipment until the end of March. A single pass of the test full charge/discharge takes almost 24 hours per pass. I can test 4 cells concurrently and will likely have the full first pass with the used 2018 cells done later this week.
Does anyone know of a source for a four authentic new Tesla 2170s cells? I can be discrete and can return the cells when testing is done if helpful. If anyone has seen a real 4860 I could be convinced to give that a look a too! Please DM if you can help. Thanks
