12V racing battery recommendations

A few years ago my car wouldn't start for the semi finals at a race and I decided that this was not going to happen again.
Now between rounds I run the fan and water pump from the (2) deep cycle batteries in the trailer normally for the winch and jack. I run 4 ga cables to a switch box and then 4 way cable to a 4 pole plug. The 4 way socket in the car is wired in parallel to the normal wires.
