> That battery seems expensive (most expensive part?)
At first, I was like "Nah, just looks like my RC car battery", but then I Googled it...and it's a whopping $1,305 [0].
I looked closer at the specs and they're insane for a battery as small as it is. They have double the energy density as measured by both volume and mass compared to my RC car batteries [1].
