  1. I have 2 optima g27 batteries for my engines(Yamaha 250) and 2 of the same as house batteries. if I want to replace one house battery with the Odyssey 31-PC2150S and leave it joined with the other optima house battery which are all paired together for charging purposes, will I encounter any problems? ie: g27 grouped with a g31. if that isn’t a problem, what about just using just 1 Odyssey 31-PC2150S as the house. There is also an electric Bow thruster connected to the house and it requires MCA 1150. hope I’m clear enough for you.
    Thanks for your help,
