Product Details

The NewMar BI-200 Battery Integrator is an intelligent charging solution that enables simultaneous charging of multiple battery banks without voltage drop while maintaining complete isolation during discharge. This automatic switching device connects independent battery banks only when charging voltage is present, preventing secondary batteries from draining into primary batteries when the charging source is off.

How It Works:

The BI-200 functions as a smart switch that automatically integrates battery banks when it detects charging voltage of approximately 13.2 VDC or higher from an alternator or battery charger. When voltage drops below 12.8 VDC, the unit disconnects the banks to allow selective discharge. Unlike diode isolators, the Battery Integrator introduces zero voltage drop in the charging circuit, ensuring maximum charging efficiency for all connected batteries.

Key Features:

  • 200 amp continuous duty rating with 600 amp peak capacity for high-demand applications
  • Heavy-duty silver-plated contactor designed for marine and RV environments
  • Epoxy-encapsulated voltage sense circuits for moisture and corrosion resistance
  • Ignition protection rating for safe installation in engine compartments
  • Simple three-wire installation for two-bank systems (Battery +, Battery +, Ground)
  • Optional remote indicator light terminal shows when banks are integrated
  • Manual override capability can be wired through key starter for emergency boost during engine starting
  • Maintains 100% battery isolation when charging source is not active

Technical Specifications:

  • System Voltage: 12 VDC
  • Integration Voltage: 13.2 VDC
  • Disconnect Voltage: 12.8 VDC
  • Continuous Current Rating: 200 Amps
  • Peak Current Rating: 600 Amps
  • Battery Terminals: 5/16 inch copper alloy studs
  • Operating Temperature Range: Control circuits -40°F to +185°F, Solenoid -18°F to +118°F
  • Dimensions: 4 x 3.3 x 4.1 inches (H x W x D)
  • Weight: 2 lbs
  • Certification: CE Marked with ignition protection rating

Applications:

Ideal for marine vessels, RVs, motorhomes, and commercial vehicles requiring efficient charging of house and starting battery banks. For systems with three or more battery banks, additional BI-200 units can be installed for each additional bank beyond the primary two.
