In a boat or vehicle with two battery banks, it is useful to be able to charge both banks while underway. Charge management devices allow two battery banks to be charged from a single source, such as an alternator, but keep batteries isolated when not charging. If one battery becomes depleted, there will be a charged bank available for emergency starting.

Battery management is central to safe operation of a boat or vehicle. A battery switch is required by ABYC in every boat with a battery over 800 Cold Cranking Amps (CCA). This requirement exists, so the potentially destructive energy in the batteries can be isolated in the event of a fire.

Circuit breakers protect the wire in electrical circuits. Blue Sea Systems broad selection of magnetic and thermal circuit breakers include a vast selection of main and branch circuit protection devices. Their robust design makes them ideal for marine and vehicle AC & DC electrical systems

The nuts and bolts of any electrical system are the connectors which keep the current flowing. Blue Sea Systems connectors reduce heat and improve efficiency and reliability in a boat's electrical system. The features below make Blue Sea Systems connectors stand out from the others.

Best Practices and ABYC standards state that every positive wire on the boat outside the engine starting circuit must have circuit protection. When excessive current flows in an electrical circuit, wire insulation can melt and possibly start a fire

At the heart of a boat's electrical system is the power distribution panel. Blue Sea Systems manufactures panels for small runabouts to large offshore cruising yachts, with four panel styles to choose from.
