Lithium Pros

<h3>About Lithium Pros</h3><p>Founded in 2011 and headquartered in Knoxville, Tennessee, Lithium Pros was built by a team of energy and motorsport enthusiasts on a single, clear mission: bring the highest-performance, ultra-lightweight lithium-ion batteries to the marine, racing, EV, fleet, and specialty markets. The people behind Lithium Pros aren't just engineers — they're competitors. The team includes drag racers, drifters, off-road racers, SPL and SQ audio competitors, alongside experienced chemists and machinists who understand exactly what it takes to build a battery that performs under real-world punishment.</p><h3>What Sets Lithium Pros Apart</h3><p>The core of every Lithium Pros product is Lithium Iron Phosphate (LiFePO4) chemistry — a stable, high-density cell technology that delivers meaningful advantages over traditional lead-acid batteries. Lithium Pros batteries are approximately three times the energy density of comparable lead-acid units, meaning more power in a dramatically smaller and lighter package. In fact, some models are light enough to float — a genuine advantage for both racing weight reduction and marine buoyancy safety.</p><p>Beyond sheer power density, Lithium Pros batteries hold a higher terminal voltage under load than lead-acid alternatives, translating to hotter ignition, faster cranking, and more consistent current delivery to onboard electronics and accessories. Their LiFePO4 cells are also rated for over five times the charge cycle life of standard lead-acid batteries, and they accept charge current up to five times faster — meaning less downtime between runs or on the water.</p><p>Lithium Pros has earned a proven reputation in competitive motorsport, with a history of use in SCCA World Challenge, Formula Atlantic, drag racing, and more. That same performance DNA carries directly into their marine lineup, which is trusted by many of the world&apos;s top professional anglers.</p><h3>Lithium Pros Product Categories</h3><p>The Lithium Pros catalog is focused and intentional. Their <a href="/18968-lithium-pros-batteries-200137">Batteries</a> lineup spans marine trolling batteries, starting batteries, and racing packs across multiple voltages and capacities — each engineered for a specific application. For anglers, boaters, and racers who demand reliable power management, Lithium Pros also manufactures a complete line of purpose-built <a href="/18968-lithium-pros-battery-chargers-200141">Battery Chargers</a> designed specifically for LiFePO4 chemistry, available in 12V, 16V, 24V, and 36V configurations. These high-frequency chargers are not afterthoughts — they are engineered alongside the batteries themselves to ensure proper charge profiles and maximum cycle longevity.</p><p>For powerboat owners and tournament anglers who need dependable starting power, Lithium Pros offers dedicated <a href="/200366-engine-batteries-lithium-pros-18968">Engine Batteries</a> built to meet or exceed current outboard manufacturer specifications, including compatibility with modern alternator systems. Whether you&apos;re replacing a heavy group-31 AGM with a single lithium unit or upgrading a racing application to a 16V system, Lithium Pros has a solution engineered specifically for the job.</p><h3>The Lithium Pros Commitment</h3><p>Every Lithium Pros product carries a 60-day risk-free guarantee, reflecting the brand&apos;s confidence in its engineering and materials. For racers, anglers, fleet operators, and EV builders who refuse to compromise on power and weight, Lithium Pros represents a technically serious, competition-proven alternative to legacy battery technology.</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.
