Yes, that would be easier.

That said, running a vehicle off its battery alone is a pretty extreme mod. Yes it will save fuel. It will also destroy a regular starting battery in short order, since they're not designed to be deeply & repeatedly dis/charged.

This is a mod I often use in summer months. But I've got a supply of old deep cycle batteries which I can ruin at will.
