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Pros was built by a team of engineers, chemists, and racing enthusiasts who shared a single obsession: replacing outdated lead-acid batteries with the most advanced lithium-ion technology available.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 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.

Showed up a day ahead of schedule, nice, thanks!

Fast shipping

There was one speaker grid missing.. It was apparent that the box had been opened previously. Please forward this to customer service - would request that missing mesh grid be sent to me. Thank you

Good Experience

Ordered replacement seats for my fishing boat. I was shocked and impressed with the quality of the seats. They look as good as the originals from Tracker. Shipping was great, arrived sooner than I expected.

Everything went well. We&rsquo;ll see how shipping goes.

good price

First time I place an order, good prices and fast shipping. Would definitely order again from them.
