Lithium Pros N31150-S 12V 150Ah Marine Starting Battery with NMEA 2000

The Lithium Pros N31150-S is an advanced 12.8V 150Ah lithium iron phosphate (LiFePO4) marine starting battery featuring built-in NMEA 2000 connectivity. This starting and deep cycle battery is designed for serious anglers who demand real-time battery monitoring directly on their multifunction displays.

NMEA 2000 Connectivity:

The N31150-S directly connects to the NMEA 2000 network with an embedded BM-21 battery monitor that is NMEA 2000 certified and features a micro port on the battery, making it plug and play with all NMEA 2000 multi-function displays. The system displays individual battery voltage, current, time remaining, state of charge, and temperature all on the network.

Key Features:

• Meets the Sept 19, 2022 Mercury specifications for a lithium-ion engine start battery
• Compatible with all outboards and alternators
• Replace two group 31 AGM batteries with this ONE battery
• Ultra lightweight at approximately 36 pounds—that's 1/4 of the weight of two Group 31 AGM batteries
• High power Lithium Iron Phosphate chemistry holds a higher voltage as it is discharged, eliminating graph reset issues during engine cranking
• Accept charge current up to five times faster than lead-acid batteries
• Provides over five times the cycle life with 2,500+ cycles at 80% depth of discharge
• 96% efficient at converting input energy into stored energy versus approximately 75% for lead acid

Specifications:

• Voltage: 12.8V
• Capacity: 150Ah
• Chemistry: Lithium Iron Phosphate (LiFePO4)
• NMEA 2000 certified with BM-21 embedded battery monitor
• Compatible with existing 12V AGM battery chargers
• BCI Group 31 size

Ensure the charger's float voltage is 13.5V or less and never exceeds 14.8V. Not for use in series to make higher voltage packs—12V systems ONLY.
