Not my area, but the best info I can find around is somewhere in the region of 200-250Wh/kg at the top end for current typical lithium ion batteries. I&#x27;m not sure if that&#x27;s the type they&#x27;re using. https://batteryuniversity.com/learn/article/types_of_lithium... https://arxiv.org/pdf/1803.04317.pdf https://en.wikipedia.org/wiki/Lithium-ion_battery</p><p><a href="https://hackerpaper.kaipfister.de/p/1803.04317/">Paper and discussion history</a>.
