Lithium Pros

<h3>About Lithium Pros</h3><p>Founded in 2011 and headquartered in Knoxville, Tennessee, Lithium Pros was built by a team of engineers, chemists, and racing enthusiasts who shared a single obsession: replacing outdated lead-acid batteries with the most advanced lithium-ion technology available. Rather than adapting existing battery designs, the company set out to engineer purpose-built solutions for the demanding worlds of motorsports, marine fishing, recreational vehicles, EV conversions, and fleet applications.</p><p>What separates Lithium Pros from commodity lithium suppliers is the depth of real-world experience behind every product. <strong>Their first lithium-ion batteries were 16V packs developed specifically for Pro Nitrous, Pro Mod, and Pro Stock drag racing applications</strong> — environments where weight, power delivery, and reliability are non-negotiable. That racing DNA carries through the entire product line today, with batteries that hold a higher voltage under load, recharge up to five times faster than lead-acid equivalents, and deliver up to three times the energy density in the same footprint.</p><p>The marine lineup is equally impressive. The flagship <strong>M Series</strong> and <strong>N Series</strong> LiFePO4 batteries are engineered specifically for tournament anglers and serious boaters, offering exclusive cold-weather functionality and — in the N Series — built-in NMEA 2000 connectivity that feeds accurate state-of-charge data directly to compatible multifunction displays. Some models are light enough to float, a testament to the extreme weight savings lithium chemistry can provide over traditional AGM or flooded lead-acid packs.</p><p>Lithium Pros also understands that a great battery is only as good as the charger keeping it healthy. Their lineup of <a href="/18968-lithium-pros-battery-chargers-201677">battery chargers</a> is purpose-engineered to match the specific voltage profiles and charge characteristics of their LiFePO4 cells, spanning 12V, 24V, 36V, and 48V configurations for both marine and racing applications. High-frequency designs deliver smooth, consistent output voltage that extends battery life over thousands of cycles, and universal AC input compatibility means they work equally well in the garage, at the dock, or in the pits.</p><p>Backed by a 60-day risk-free guarantee on every product and assembled and tested in Tennessee, Lithium Pros stands behind its technology with the confidence of a brand that has powered some of the fastest vehicles — and most productive fishing boats — in the country.</p>

Product Details

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.

Good experience
