Analytic Systems 200A 40V 3-Bank Ideal Battery Isolator One Size. 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.
