Thank you for your very thorough reply Woodcote!

I have read "somewhere" that it can better, yes. But to that point I already own one so it would just be a matter of connecting it. I only have the one power supply that came with the ArcPro powerbase, So geting a second would be sufficient then. 

But I will look into the power booster cables - it looks fairly easy to build your own.

P.S
Woodcote is my favourite corner at Goodwood :) Been there several times for the Revival.
