COSUPER battery isolator allows the dual battery to be charged from the single power supply such as alternator, battery charger or solar charger. Because of the unique ability to pass current in one
direction, the first battery bank can be discharged without draining from the second battery bank.
With this isolator operating in the system, the power would not be taken from engine’s battery, keep your main battery to be fully charged.
