Speaking of batteries. I will be using an auger/drill set-up for the first time this season. A guy that I fished with had one and he told me that while the cold does have an effect on battery life, getting them wet can be just as hard on them. So I am thinking of wrapping the battery in a piece of thin foam sheating (or something similar) and slipping a water-proof bag over it while in use, keeping the spare battery in a warm, dry place. Think this will help?
