Thread: How big for starter battery?

I like the idea of a second battery and was going to have one up front for electronics to run off.
Is it a good idea to have the "House" battery ready to boost the starting battery if it needs to for some reason? If so what size cable would be able to carry enough juice to help?

Thats what I have one battery purely for Start / Winch and everything else comes off the 140AH Deep Cycle. I have an "Emergency Parallel" Switch fitted in the event the start battery fails but this is unlikely (given the Start battery is only for motor and winch is only operated with motor running) but its there just in case.
Both batteries are down back of boat with 5mm2 2 core from Deep Cycle supplying electronics etc up front.
Hope that helps with a older motor you might need a vsr if you only have a single charging circuit
