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Pros was built by a team of engineers, chemists, and racing enthusiasts who shared a single obsession: replacing outdated lead-acid batteries with the most advanced lithium-ion technology available.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 L31-36 is a 36V / 67Ah Lithium Iron Phosphate (LiFePO4) deep cycle trolling battery built in a standard BCI Group 31 form factor. Designed for 36V trolling motor systems, this single battery replaces three conventional Group 31 lead-acid or AGM batteries, dramatically reducing onboard weight while delivering all-day power on the water.

Key Features:

  • 36V / 67Ah capacity — approximately 2,570 watt-hours of usable energy
  • 160 reserve minutes — extended trolling runtime from daylight to dark
  • BCI Group 31 footprint — fits standard marine battery trays (13″ L x 6.81″ W x 8.43″ H)
  • Only ~39.8 lbs — replaces three Group 31 batteries that together weigh over 200 lbs
  • Built-in Bluetooth connectivity — pairs with the free LP Battery View app to monitor State of Charge, time remaining, voltage, amperage, and cell temperatures
  • Internal Battery Management System (BMS) — auto-balances cells and protects against over-voltage, under-voltage, over-temperature, over-current, and short circuit conditions
  • 96% charge efficiency — vs. approximately 75% for lead-acid batteries
  • LiFePO4 chemistry — inherently stable and safe lithium iron phosphate cells tested to UL1642 standard
  • IP67 water resistant — sealed for marine environments
  • 3,000+ cycle life — long-term value vs. lead-acid alternatives
  • Compatible with on-board DC chargers and third-party systems such as the Power-Pole CHARGE™

Important: Requires a 38.4V LiFePO4-compatible battery charger (sold separately). Not compatible with standard 36V lead-acid chargers.

The L31-36 is the ideal upgrade for freshwater and saltwater tournament anglers running 36V trolling motors who demand maximum runtime, minimal weight, and real-time battery monitoring in a direct-fit Group 31 package.
