Here is a new video from Donut Lab about the second in a series of third party tests being performed on its solid-state by VTT Technical Research Centre of Finland.
They tested the Donut battery at a deliberately high temperatures to test its performance under high heat stress.
They discharged the battery in a heated testing chamber of 80 C and 100 C and measured its performance. Then compared those results to the battery operating at room temperature. In the high heat environment the battery operated normally, and actually was able to discharge more energy than when operating at room temperature.

Here is a video from the Two Bit da Vinci website analyzing the results of this test.
