I have 3 batteries in my boat; one 12 volt for the engine and components, the other two attached in series to make 24 volts for my trolling motor. I am looking to buy a charger that will be the easiest in terms of charging as so I do not have to manually attach a portable charge. I have seen the on board chargers that will automatically charge the battery when needed and or trickle charge the battery over months for maintenance.
Bass Pro Xps Charger


Xps 3 Bank Battery Charger
Can't figure out what's going on with my onboard charger. Have a two bank. Needless to say the batteries were not charged. Here's the info from the XPS manual that you can use to check into your problem. All the newer 'smart' chargers are designed to be on as long as you are not using the boat.
