Newmar Power BI-200 Battery Integrator for Marine and Automotive Applications

BI-200 Battery Integrator

Charging multiple battery banks without the use of diode isolators dictates that the batteries be connected or integrated only whenever a charge voltage is present so that they may be charged simultaneously, then disconnected or isolated when the charge voltage is no longer present to allow for selective discharge and avoid having the secondary or standby battery drain into the primary battery.

Battery integrators perform this function automatically, acting as a smart switch to connect independent battery banks only when a charging voltage is present. Otherwise, they are isolated, and discharge between banks is prevented.

The Battery Integrator causes no voltage drop in the charging system, while the multiple batteries are charged as a single bank whenever a charging source of approximately 13.2 VDC or 26.4 VDC or greater is present (depending on the model).

When the alternator or charger is off or a large load causes the voltage to drop below the disconnect point, the unit breaks the common tie between the banks. This allows selective battery discharge and prevents the dumping of a higher-charged bank into a lower-charged bank. The unit may also be remotely activated to connect other batteries through the key starter or a manual switch to provide an added boost from the secondary battery whenever the starter is engaged and the unit senses there is sufficient voltage in that battery to provide an assist.

Features:

• Enables charging of two separate banks without voltage drop yet maintains 100% isolation at all other times. For systems of three banks or more, an additional unit must be installed for each additional bank
• Heavy-duty silver-plated contactor, continuous duty rated to 100 Amps or 200 Amps depending on model
• Voltage sense circuits, epoxy-encapsulated, and heavy-duty continuous-rated solenoids are all designed for use in marine environments
• Has ignition protection rating
• Easy three-wire hookup for two bank systems (BATT +, BATT +, GROUND)
• Terminal for optional wiring of a remote light indicating when battery banks are integrated
• Optional internal connections can be wired through the key starter or manual override switch, tying battery banks together for an extra boost during engine start

The Newmar Power BI-200 Battery Integrator is an advanced device designed to optimize the charging and management of multiple battery banks in marine, RV, and automotive systems. It intelligently connects or isolates battery banks based on the presence of a charging voltage, ensuring efficient charging without voltage drop and preventing unnecessary discharge between banks. This automatic operation simplifies system wiring and enhances battery longevity by maintaining proper isolation during discharge cycles.

Featuring a heavy-duty silver-plated contactor rated for 100 or 200 amps depending on the model, the BI-200 is built for durability and reliable performance in demanding environments. The device incorporates epoxy-encapsulated voltage sense circuits and heavy-duty solenoids, making it suitable for marine environments where moisture and vibration are common. Its ignition protection rating adds safety, allowing installation in various vehicle and vessel configurations without risk of ignition sources.

The unit offers straightforward wiring with a three-wire hookup system (BATT +, BATT +, GROUND) and includes a terminal for optional remote indicator lights. It can be remotely activated via the key starter or manual switch, providing additional battery boost during engine startup by connecting secondary batteries when sufficient voltage is detected. The system operates on 12 VDC, with a typical battery integration point at 13.2 VDC and disconnect at 12.8 VDC, supporting continuous currents up to 200 amps and peaks of 600 amps for short bursts.

Designed for ease of installation and use, the BI-200 is CE marked and measures approximately 4 x 3.3 x 4.1 inches, weighing around 2 pounds. Its operating temperature range from -40°C to +85°C for the control unit and -28°C to +48°C for the solenoid ensures reliable operation in a wide range of environmental conditions. This device is ideal for systems requiring multiple battery banks to be charged efficiently and safely, providing seamless integration and isolation functionality to improve system performance and battery lifespan.

Features:

• Enables charging of two separate battery banks without voltage drop while maintaining full isolation at other times. Additional units are required for systems with more than two banks.

• Heavy-duty silver-plated contactor rated for continuous operation at 100 or 200 amps depending on model.

• Epoxy-encapsulated, heavy-duty voltage sense circuits and solenoids designed for marine and harsh environments.

• Ignition protection rating for safe operation in automotive and marine systems.

• Easy three-wire hookup for two bank systems, including connections for batteries and ground.

• Includes a terminal for optional remote indicator lights to show when banks are integrated.

• Internal wiring options for remote activation through the key starter or manual override switch, providing an extra boost during engine start.
