Vanner Battery Isolator, Silicon Isolator 2 Battery Bank, 180 Amp Alternator

Battery Isolators in Operation 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. For example, a typical vehicle system may use one battery dedicated to the engine (starter, ignition, etc.) And the other battery dedicated to a DC to AC inverter. With the engine running, the alternator will supply charging current to both batteries. With the engine off, the DC to AC inverter could continue to operate, discharging 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. Schottky battery isoltors are designed to ...
