Its not the best picture but here on the left you can see there are 4 wires connected to the VESC. The larger 2 go to the battery, the slightly smaller 2 go to a set of 3 1800uF 63V caps. These helped smooth out the power delivery to the VESC and reduce any spike loadings on the batteries; one of the reasons why CnS accelerate so quickly is because the VESC's get the power as soon as they want it.
This is probably as close as you can get them to the board besides them being physically wired to the board itself, so this is what you are aiming for. I would over spec on voltage just to be on the safe side; so if you are 24V, go 36, something like that, and you want as much capacity as you can get away with; within reason.
Still managed to blow up two of them even with those caps...
