MasterVolt 83116035 Battery Mate 1603 IG Isolator 160A 3 Bank

The MasterVolt Battery Mate 1603 IG is an advanced electronic battery isolator designed to charge up to three batteries simultaneously with negligible voltage drop. Compatible with any type of alternator or battery charger in both 12V and 24V systems, this isolator is ideal for marine, RV, and automotive applications requiring independent battery bank charging.

Advanced MOSFET Technology:

Unlike conventional diode-based battery isolators, the Battery Mate utilizes electronic MOSFET (transistor) technology that virtually eliminates voltage loss between the alternator and batteries. This ensures fast, complete charging without requiring alternator adjustments. The advanced components automatically compensate for voltage variations and maintain the correct charging voltage across all battery banks.

Key Features:

• 160A maximum alternator current (intermittent), 120A continuous charger current
• 3 battery outputs for independent charging of multiple battery banks
• Minimal voltage drop: less than 0.4V (only 0.1V at 20A)
• Automatic voltage detection for 12V or 24V systems (8-30 VDC input range)
• LED power indicator for clear status monitoring
• DIN rail mounting for fast, industry-standard installation
• IG (ignition) contact for alternators requiring external excitation or voltage sensing
• Operating temperature range: -40°C to +120°C (-40°F to +248°F)
• Corrosion-proof construction with aluminum heat sinks

Specifications:

• Dimensions: 8.1" x 5.5" x 3.1" (207 x 140 x 80 mm)
• Weight: 2.2 lbs (1 kg)
• Insulation to ground: >500V @ 60Hz
• Solid bolt connections with nuts and locking rings

The Battery Mate prevents current from flowing between batteries while ensuring optimal charging performance. Input connects to your alternator and/or battery charger, while outputs connect to two or three independent battery banks. Perfect for boats, RVs, commercial vehicles, and any application requiring reliable multi-battery charging management.
