Intelligent Battery Management for Multi-Engine Marine Systems

BEP Marine’s Smart Battery Hub (SBH) is an innovative, first-of-its-kind intelligent battery management system designed for vessels equipped with two or more outboard, sterndrive, or inboard engines. The SBH simplifies power control with advanced remote operation, automatic dual-direction Voltage Sensitive Switching (VSS), and emergency parallel functionality—all housed within a robust, ignition-protected IPX7-rated enclosure.

Designed for seamless integration, the SBH transmits critical battery data, including individual voltages and house bank state of charge, over NMEA2000 for easy monitoring through multi-function displays. With configurable VSS voltage thresholds, assignable switch inputs, and additional sensor inputs, this system provides complete flexibility for optimized marine power management. Remote switching is facilitated via NMEA2000 or wired switches, while manual override ensures safety and reliability in all conditions.
