A 12V DC 100A microprocessor-controlled, dual battery isolator designed to protect the start battery from excessive discharge while allowing the auxilliary battery to
supply charge to non-essential loads.
It is better than a diode battery isolator due to the voltage drop associated with diode type isolation. It features a low standby current draw and sophisticated fault
detection and LED indication of operation to warn the user of faults including over-voltage, voltage drop and excessive current draw conditions.
