So in my setup I am planning on connection my 12}12}30 to the COMMON of a 1{2{BOTH battery switch. Terminal 1 is my starter battery, terminal 2 is a lead acid house battery. On the other side of the Orion I have a 200ah LifePo4 bank. I plan on setting the start-charging voltage so it only activates when the engine is running ( alternator pushing voltage ). My question... when the engine is OFF ( Orion is not charging ) Does it completely disconnect the circuit. ie not let voltage from the Li bank cross the Orion to the battery switch? ( I think the answer has to be YES, but want to confirm )
