Spring is in the air (give me a break, it will be soon) and I want to start a “to do” list for the boat. I’m looking for good information on rigging my boat batteries. What do you guys know of or recommend for on-board battery chargers? Is it possible to have 2 or 3 batteries all hooked to a charger at once? New decking and a paint job for the boat are high on my list this year, but I’d really want to simplify caring for my batteries.
