Dual batteries for winching

Gday I am hoping someone can help me in how to wire up dual batteries for a winch. I have an overlander 700 (this is my starting battery) and the new optima (d31a) yellow top to give the winch a bit more go. This battery will be inside the car as there is no space in engine bay and I am opting for 20mm wire to minimise current drop.
Any help will be grateful cheers

Are you saying they're 70mm diameter!?
Did you steal some wiring from an 240V electrical substation?

They are 70mm squared which is bigger then ya thumb
And no they are not from a sub station, they are proper automotive cables. The cable we use that work has much bigger strands in it which would break to easly with the vibs and movement of a 4x4. Plus sub station have closer to 200mm plus cables
