Millertech 2 Bank charger 36volt-12volt charger

This charger works great being able to charge my 36 volt lithium trolling motor battery and my 12 volt lithium electronics battery at the same time.

Battery charger

Haven’t put the charger in the boat yet. It’s freezing in Minnesota. I did hook up and put a full charge on both batteries. So far so good. More to come in the spring when I get it all set up in the boat
