Mastervolt Battery Mate 1602IG Battery Isolator 120A 2 Battery

The Mastervolt Battery Mate 1602IG Battery Isolator is a compact, two-bank charging solution designed for boats and other multi-battery setups, delivering independent charging with minimal voltage loss.

• Two battery outlets: Dedicated connections for two battery banks to enable independent charging without cross-charging.
• MOSFET isolation: Electronic MOSFET-based isolation that compensates for voltage loss and maintains correct charging voltage across banks.
• Low voltage drop: Designed to deliver negligible voltage loss so loads stay powered reliably.
• Rugged construction: Corrosion-proof materials with aluminium heat sinks, synthetic end plates, and solid bolt connections for long-lasting performance.
• Fast, easy installation: End plates include connection lugs; bolts and locking rings simplify mounting and wiring.
• Universal compatibility: Works with any alternator or battery charger in existing or new systems, delivering optimal charge without adjusting your alternator.
• Ideal for multi-bank charging: Designed to charge two or three batteries (possibly from different brands of alternators) with high yield and no voltage loss.
• Status indicator: LED display shows when the power input is active for quick, at-a-glance monitoring.
• Max. output to batteries: 120 A
• Max. input (alternator): 160 A
• Dimensions (HxWxD): 8.1 x 5.5 x 3.1 in
• Weight: 2.2 lb
• Number of battery outlets: 2

This isolator helps you efficiently manage two battery banks in 12/24 V systems, enabling independent charging without cross-charging. The MOSFET-based isolation minimizes voltage drop, so your loads stay powered reliably. Its rugged, corrosion-resistant build and straightforward installation make upgrading straightforward, while universal compatibility lets you pair it with any alternator or charger and scale to two or three batteries for more dependable power on the water or off-grid.
