Upgrade your onboard power management with the Mastervolt Battery Mate 1602IG Battery Isolator, a compact 120 A isolator designed to manage two battery banks efficiently. It delivers negligible voltage drop, so your 12 V or 24 V consumers always receive the power they need while batteries stay isolated for independent charging.

• Electronic isolation with MOSFET technology — Unlike conventional diode splitters, Battery Mate uses advanced electronics to compensate for voltage loss and ensure charging voltage stays correct across multiple battery banks.
• Two battery outlets, robust construction — Corrosion-proof materials with aluminium heat sinks; synthetic end plates and solid bolt connections for reliable, long-lasting performance.
• Fast, easy installation — End plates feature 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.
• Performance specs — Max output to batteries: 120 A; max input (alternator): 160 A; Number of battery outlets: 2; Dimensions: 8.1 x 5.5 x 3.1 in; Weight: 2.2 lb.
• Status indicator — LED display shows when the power input is active for quick, at-a-glance monitoring.

Notes: Models 1602/1603 support up to 160 A alternators; the Battery Mate 2503 targets higher-current setups up to 250 A. If you need efficient, independent charging for multiple batteries in your 12/24 V system, the Battery Mate 1602IG provides fast, complete charging with minimal voltage drop and easy installation.
