When i fire up and take off I can watch my batteries on a selectable gauge I have installed on my dash. Usually my motor fires in just a few crank, seconds. That doesn't use up much battery power. i can watch the charger switch the power over tot eh aux batteries in just a few minutes after i get going. I think dual pro claimed about 30% average more
run time on your trolling motor with this setup. I know I have seen a big difference, especially if I move several times during the night. Which I usually do move if the bit is not happening.
Just my two pennies worth again.:big_smile:
