Product Details

The NewMar BI-100 Battery Integrator is a smart automatic switching device that enables simultaneous charging of multiple battery banks without voltage drop, while maintaining complete isolation during discharge. Designed for marine and RV applications, this unit connects independent battery banks only when a charging voltage is present, preventing drain between banks when the alternator or charger is off.

How It Works:

The BI-100 automatically integrates battery banks when it detects a charging voltage of approximately 13.2 VDC or greater, allowing batteries to charge as a single bank with zero voltage loss. When voltage drops below 12.8 VDC, the unit disconnects the banks to enable selective discharge and prevent a higher-charged bank from draining into a lower-charged bank. An optional remote activation feature can tie batteries together through the key starter for extra cranking power during engine start.

Key Features:

  • Zero voltage drop charging with 100% isolation during discharge
  • Heavy-duty silver-plated contactor rated for continuous 100 amp duty, 400 amp peak
  • Epoxy-encapsulated voltage sense circuits for marine environment durability
  • Ignition protection rating for safe installation
  • Simple three-wire hookup for two-bank systems (battery positive, battery positive, ground)
  • Terminal for optional remote indicator light showing integration status
  • Optional manual override switch for extra boost during engine start
  • CE marked and designed for harsh marine environments

Technical Specifications:

  • Voltage: 12 VDC
  • Battery integration point: 13.2 VDC
  • Battery disconnect point: 12.8 VDC
  • Maximum continuous current: 100 Amps
  • Peak maximum current: 400 Amps
  • Battery terminals: 5/16 inch copper alloy stud
  • Operating temperature: Control -40°F to +185°F, Solenoid -18°F to +118°F
  • Dimensions: 3 x 3.25 x 2.5 inches (H x W x D)
  • Weight: 1 lb

For systems with three or more battery banks, an additional BI-100 unit must be installed for each additional bank beyond the first two.
