2-Bank Battery Isolator, 200A, 40VAnalytic Systems introduces the IBI (Ideal Battery Isolator) for 1, 2 and 3 bank battery systems, allowing all the batteries to be fully charged from a single alternator while maintaining electricalisolation between the battery banks or between a vehicle andtrailer.Ideal Diode technology uses MosFet Transistors and controlcircuitry to replace the diode used in a traditional battery isolatorand reduces the voltage drop across the isolator to a mere 160millivolts at 200 Amps of charging current and essentially zerovolts at low current, so all the power of the alternator is applied tothe batteries ensuring a full recharge every time.While the Ideal Battery Isolator is designed to be used with an alternator, it can also be used to convert a single bank battery charger to a 2 or 3 bank charger or as a pure diode between a vehicle and trailer or other remote load.Features:Waterproof Expoxy Sealed ConstructionEasy ConnectionAlternator/Charger post 5/16″, Battery Post 1/4″Most Efficient use of Available Alternator OutputMaximize Battery PerformanceThree year parts and labour warranty
