Batt Charger
I just recently installed a 10 amp, 3 stage, waterproof, 2 bank guest in my 78 Catalina. I installed it in the compartment under the port outside bench. My Batteries are located by the engine. This location is close to my electrical panel, provides fairly short wire lengths (for minimal voltage drop) to both batteries and proper ventalation to allow the charger to operate at cool temps. It also puts it in an easily to see and reach location to monitor charging status.
