So i have 2 batteries on my boat and an onboard battery charger like this one. I need to replace one of the batteries so i went to disconnect things and realized something strange. The charger has 3 outputs that go to the batteries and 2 of them were both hooked to 1 battery and the other output goes to the 2nd battery. I assume there isn't any harm in having two outputs go to 1 battery, right? One for each battery is sufficient and i could just disconnect the 3rd output right?
