Xri cranking battery cca requirement?

[xb03fs]

Trying to decide on getting an oversized one and running the troller off or just dedicating a smaller one to cranking and accessories

Unless you're built like a gorilla and would like to rope start it, I wouldn't run trolling equipment on the starting battery. I believe you have the two regulator 40 amp system. Easy to split, and use one regulator to maintain the starting battery, and the other for a 12 volt trolling battery, or a 12/24 system.
