Detailed description
Detailed description
The 12V 300Ah Solid State Marine house battery redefines onboard energy storage standards. Designed to directly replace lead-acid or lithium battery banks in BCI Group 31 format, it uses high-density solid-state cell technology. This liquid-electrolyte-free architecture provides absolute safety against fire and thermal runaway risks. Weighing approximately 20 kg (44 lbs), it is twice as light as a traditional LiFePO4 battery and six times lighter than an AGM battery, while delivering massive energy storage of 4320 Wh.
Performance
The system handles continuous discharge currents of 250A to 300A, with acceptable peaks up to 500A via the BMS, enabling simultaneous power supply to bow thrusters, windlasses, and demanding onboard electronics.
Smart management and system integration
The integrated battery management system (BMS) ensures comprehensive protection: cut-off in case of overvoltage (16.8V), undervoltage (10.08V), and extreme temperatures. Operation is guaranteed from -20°C to 65°C, with native short-circuit protection (1000A for 2 ms). The battery includes Bluetooth connectivity for monitoring via the SSM Battery Monitor app and is available in versions compatible with NMEA 2000, CAN, RS-485, or with Victron integration for direct supervision on your multifunction chartplotter.
Fast charging and durability
Certified IP67 and compliant with UN38.3 and UL1642 test standards, the battery withstands the harshest marine environments. It accepts fast charging currents up to 300A (1C). For optimal 100% charge, a voltage of 16.5V to 16.6V is required (specific configuration needed on chargers such as Victron IP43 or IP65). It offers a lifespan exceeding 3000 cycles at 80% depth of discharge (DOD).
