Vanner battery isolators allow dual batteries to be charged from a single power source such as an alternator or battery charger. Due to the isolator’s ability to pass current in only one direction, your first battery can be discharged without draining power from the second battery. With a battery isolator operating in the system, the power would not be taken from the engine’s battery, keeping it fully charged. Vanner manufactures both silicon and Schottky type battery isolators. Both types utilize a special heat sink design for excellent heat dissipation and heavy-duty wiring terminals. Vanner battery isolators operate on both 12 and 24 volt DC electrical systems.
