Add a Battery Package

Blue Sea Systems Add a Battery Charger and Switch Package includes the award winning Dual Circuit Plus battery switch and the new SI Series automatic charging relay, making it a complete battery bank management solution.

The switch can be surface or rear panel mounted which provides a wide array of mounting locations. E-Series selectors allow users to switch between two battery banks simultaneously with one simple ON/OFF switch while maintaining battery bank isolation, minimizing the risk of a dead Starting battery.  

The BOTH function offers the ability to combine the two battery banks in parallel, in the event of a cold start that may require higher cranking amps.

The 120 amp SI-Series Automatic Charging Relay allows temporary isolation of house loads from engine circuit during engine cranking to protect sensitive electronics. It activates from any charging source (alternators, battery chargers, or solar panels) and is ignition protected making it safe for gasoline applications.
