Dual Battery wiring systems

To break the trend. I am not a fan of the SmartStart. I find they lack versatility. I much prefer the Colhersie switch with the both option on it. Yes it is manual and requires turning the dial, but it gives you an option of battery A, batthery B, battery off, and both batteries. Great if you need to jump something else. Of courseyour choice will depend on what other battery you are running.
If your second battery is Deep Cycle then a SmartStart is fine. They are only good for accessories so you cant start off them anyway. (well you can but it will cause electrical problems somewhere). But if you want to start your car as well then use a normal battery and a Manual switch.

I am really only running the winch off the second battery, but I'm sure more acc will appear over time !
Thanks for your input.
