Battery Powered

Re: The Rutherford engines are fed by electric motors

- ...and the electric motors are powered by three batteries. In the video during second stage firing, you can see 2 of the 3 batteries being ejected when they have been exhausted (just after a "hot swap" comment), to reduce the second stage mass and allow a heavier payload / higher acceleration.
