Newmar Power BI-100 Battery Integrator for Dual Battery Management

BI-100 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
• 12 volt, 100 amp model has an ignition protection rating
• 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-100 Battery Integrator is an essential component for efficient management of dual battery systems in marine, RV, and automotive applications. Designed to automatically connect or isolate independent battery banks based on the presence of charging voltage, this device ensures optimal charging and discharge control without voltage drop across the system. When a charging source of approximately 13.2 VDC or higher is detected, the integrator links the banks, allowing them to be charged simultaneously as a single unit. Once charging stops or voltage drops below the set threshold, it isolates the banks to prevent unintended drain or discharge between them, maintaining the health and longevity of each battery bank.

The BI-100 features a heavy-duty, silver-plated contactor rated for continuous operation at 100 or 200 amps, depending on the model, and is built with epoxy-encapsulated voltage sensing circuits optimized for marine environments. Its easy three-wire hookup simplifies installation in two-bank systems, providing reliable operation with minimal wiring complexity. The device also includes a terminal for optional remote indicator wiring, allowing users to monitor battery integration status visually. Additionally, internal wiring options enable the unit to be remotely activated or manually overridden via the ignition or a manual switch, offering extra support during engine start or high-demand situations.

Compact and robust, the Newmar Power BI-100 measures approximately 3 inches by 3.25 inches by 2.5 inches and weighs just 1 pound, making it suitable for most installation environments. It operates effectively across a wide temperature range from -40°C to +85°C for the control and -28°C to +48°C for the solenoid, ensuring reliable performance under varying conditions. Approved with the CE mark, this integrator provides a dependable solution for managing multiple batteries without sacrificing system efficiency or safety, making it an ideal choice for those seeking a seamless and automated battery management system in demanding environments.
