Lithium Pros N75-36 38.4V 75Ah LiFePO4 Marine Trolling Battery with NMEA 2000

The Lithium Pros N75-36 (N3275-36) is an advanced 38.4V 75Ah lithium iron phosphate (LiFePO4) marine trolling battery engineered for 36V trolling motor applications. Designed to replace three traditional Group 31 AGM batteries with a single unit, this battery dramatically reduces onboard weight while delivering exceptional capacity and endurance for a full day on the water.

Key Features:

• 38.4V / 75Ah capacity — 2,850 Watt-hours of usable energy
• 173 reserve minutes of trolling power at 50% motor duty cycle
• BCI Group GC12 footprint — fits most standard marine battery trays (12.88"L x 7.13"W x 10.50"H)
• 43 lbs — a fraction of the weight of three Group 31 AGM batteries
• NMEA 2000 certified — part of the world's first lithium-ion battery series to directly connect to the NMEA 2000 network
• Embedded BM-21 battery monitor — plug-and-play NMEA 2000 port for seamless integration with compatible MFDs
• Monitors voltage, current, state of charge, remaining time, temperature, and cumulative lifetime amp-hours
• Logs warnings and alerts with real-time date and time stamps
• LiFePO4 chemistry — over 5x the cycle life of standard lead-acid batteries at 80% depth of discharge (2,500+ cycles)
• 96% energy efficiency — versus approximately 75% for lead-acid batteries
• Compatible with optional OLED display (sold separately as N3275-36D)

Note: A 38.4V LiFePO4-compatible battery charger is required. For NMEA 2000 MFD compatibility, confirm the display supports PGNs 127506 and 127508 at minimum. Also known by alternate MPN N3275-36.

The Lithium Pros N75-36 is the ideal upgrade for tournament anglers and serious boaters running 36V trolling motors who demand maximum performance, reduced weight, and integrated onboard battery monitoring.
