Blue Sea 8686 m-Series Dual Circuit Plus Panel

The Blue Sea 8686 Dual-Battery m-Series Dual Circuit Plus Panel is a twin-engine circuit protection panel that isolates the Engine circuit from the House circuit while providing 24-hour circuit protection. It is designed for boaters running twin engines who want simplified battery switch operation and independent battery discharge.

The panel protects electronics from the voltage sags and spikes that come with engine cranking, while allowing an emergency cross-connect between isolated battery banks if you ever need it. Adding an automatic charging relay automates charging on both batteries, and the panel comes with square format and 24-hour round labels included.
