its just about impossible to calculate the amount of battery capacity required as there are so many variables. Most people look at equivalent designs and use whatever worked for other builders, while others build the bot and test it to find the battery capacity required.

Having a look at other designs, Archangel's bar is heavier and almost 3 times the RPM of Scissorhands, which uses up most of a 4.2AH, 6S pack during a full length match. NST might be another example to extrapolate from. Given the much higher speed and KE of Archangel's bar, my guess is that its going to need somewhere between 2 and 4 times my battery capacity. Its beginning to look like there is a lightweight class weapon being squeezed into a featherweight ...
