This is test two, and I have to say Donut has done a good job of keeping my interest with these releases. This time they are testing hot temps, and I mean hot, 100C which is unheard of for normal battery chemistries, especially ones with a liquid electrolyte! But we dug into EVERYTHING, and there's a lot of data they may or may not have wanted us to know! Let's get into it.
