Battery Transfer SwitchesÂ
A battery transfer switch helps to prevent you accidentally running down your starter battery whilst at anchor, and then allows you to connect the house batteries to the starter battery so you can charge simultaneously both the starter and house batteries at the same time if you have only the one alienator. It also has an isolator position to isolate both batteries whilst your away from the boat.

Split Charge Relay
Split-charging is the process of sharing that charging power between the vehicle's starter battery and a secondary battery. A split charge relay acts just like a switch and is installed in-line between the two batteries. It will start charging the second battery when it detects 13.4 Volts or more and disconnect the Second battery when Voltage drops bellow 12.8V.
