The Mastervolt Battery Mate 1602 IG Isolator is a professional-grade dual-bank battery isolation and charging system designed for vehicles requiring simultaneous multi-battery management. Built for law enforcement, tactical operations, and expedition-equipped vehicles, this 120-amp isolator intelligently distributes charging current between primary and auxiliary battery banks while preventing cross-discharge and voltage drop. Whether powering communications equipment, auxiliary lighting, winches, or auxiliary power systems in the field, the Battery Mate 1602 IG maintains system integrity under demanding operational conditions.
This isolator functions as a voltage-sensitive relay, automatically connecting the auxiliary battery bank to the primary alternator circuit when charging voltage is present and disconnecting when the engine is off—eliminating parasitic drain on the main starting battery. The IG (Ignition Guard) designation indicates integrated protection circuitry that safeguards sensitive electronics from voltage spikes and reverse polarity conditions. Rated at 120 amps continuous capacity, the two-bank configuration allows independent management of separate loads, critical for vehicles running dual battery systems with independent accessory circuits. Compact dimensions (6 x 4 x 9 inches) and lightweight construction (2.5 lbs) enable flexible mounting in engine bays, battery boxes, or auxiliary power enclosures without requiring structural reinforcement.
Tactical and overland vehicles, mobile command units, and specialized law enforcement platforms benefit from the Battery Mate 1602 IG's compatibility with both original equipment and aftermarket alternators across voltage systems. Installation requires proper wire gauging and fusing per manufacturer specifications to ensure safe operation under full-load conditions. This isolator is compatible with any standard alternator output, making it ideal for retrofit applications on existing platforms or new system builds where redundant power availability is mission-critical. Regular inspection of connections and fusing ensures continued reliability in high-demand operational environments.
