With as many electrical devices as you probably use these days, having a way to charge them all while on your boat isn’t a bad idea. The Compact Perko Battery Switch provides a reliable method for managing overall use of electrical power on board for all 12, 24 and 32v systems. The fiber-reinforced polycarbonate switch gives users the ability to select between two or more batteries for engine starting, running accessories or recharging. The switches also enable use for one or more batteries with one or more engines. Should you find yourself with a dead battery, they can be placed in parallel for emergency starts.
