I think he said

As a newbie to doing things this way I've just finished put my electrics in car and want to know how and what size connectors to put on the wires for the connecting between esc and batteries or does it go buy what batteries you buy?

I want to run speed power 6500 which I've seen someone else run in a cat sx. By the way the esc is an SP GT2 Pro if that makes a difference.

Any help would be great many thanks.
