You hook it up as close to the esc as possible, located on the battery wires. It helps to reduce esc operating temps by at least 10-15*, and also helps to absorb voltage spikes from the esc > batteries. It can also help to smooth out power delivery from the batteries, by providing a steady current from the caps so that the batteries arent overdrawn during heavy load situations. or something along those lines; all I know is I added an extra novak cap to my hvmaxx and it helps smooth things out no-end, especially towards the end of the run when the batteries drop-off.
