OK, guys I am sure it has been asked before and answered but I cant find. I just replaced my 5 speed motor guide with a variable Maxuum on my 2010 Sabre to help get more run time out of my batteries. Here is my question, why is one of my batteries draining and the other showing a full charge at the end of the day? When the one starts to get weak my power goes way down yet like I said the other battery still has a full charge according to my meter. Batteries are 2 years old and the stock Continentals that came with the boat when I bought it. So I figured I would just replace both? Is the set up designed to run both at an even pace or one battery then the other? Obviously I am mechanically challenged!
