Description
Newmar BI-100 Battery Integrator | Boat Supply Store
Prevent selective discharge and parasitic drain in dual battery systems with this automatic battery integrator. It seamlessly combines battery banks when charging voltage reaches 13.2 VDC and isolates them below 12.8 VDC, maintaining a full charge on both auxiliaries and the starting bank. With a robust 100 Amp continuous current rating and ignition protection, it's engineered for the demanding marine environment, suitable for larger sportfishing vessels operating in the Gulf of Mexico.

Common Concerns Answered
Will this product cause battery drain?
No, the Newmar BI-100 is specifically designed to prevent battery drain by automatically isolating battery banks when charging is not active, ensuring neither bank is selectively discharged.
Is the peak current rating sufficient for my engine?
The BI-100 offers a 400 Amp peak current rating, which is substantial for most standard marine engine starting applications. For extremely high-demand starting systems, verify your engine's specific cranking amperage requirements against this specification.
Should I consider a dedicated battery charger instead?
A battery integrator like the BI-100 focuses on automatically managing and charging existing battery banks from a single charging source (like an alternator). A dedicated multi-bank charger provides more control and varied charging profiles for multiple batteries independently. The BI-100 is ideal for simplifying dual-battery management when an alternator is the primary charging method.
Frequently Asked Questions
How does the Newmar BI-100 Battery Integrator prevent battery drain?
The BI-100 monitors charging voltage and automatically disconnects battery banks when voltage drops below 12.8 VDC, thus preventing parasitic drain from one bank to another.
What is the voltage integration and disconnect point for the Newmar BI-100?
The BI-100 integrates battery banks at 13.2 VDC and disconnects them at 12.8 VDC.
Can the Newmar BI-100 be used for more than two battery banks?
The Newmar BI-100 is designed and rated for two battery banks. It does not support systems with more than two banks.
Does the Newmar BI-100 cause any voltage drop in the charging system?
No, the BI-100 is engineered to integrate battery banks without causing a voltage drop in the charging system, ensuring efficient power delivery.
What is the maximum continuous current the Newmar BI-100 can handle?
The Newmar BI-100 can handle a maximum continuous current of 100 Amps.
