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Pros was built by a team of engineers, chemists, and racing enthusiasts who shared a single obsession: replacing outdated lead-acid batteries with the most advanced lithium-ion technology available.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 M31-24 is a 25.6V 75Ah LiFePO4 lithium iron phosphate marine trolling battery built in a BCI Group 31 form factor. Designed for freshwater and saltwater anglers running 24V trolling motors, this single battery replaces two traditional Group 31 AGM batteries — delivering more usable power in a significantly lighter and more compact package.

Featuring integrated Bluetooth connectivity, the M31-24 pairs with the Lithium Pros LP Battery View app to provide real-time monitoring of state of charge (SoC), voltage, amperage, and battery temperature directly from your smartphone.

Key Features:

  • 25.6V / 75Ah LiFePO4 Chemistry — Stable lithium iron phosphate cells for safe, reliable high-capacity output
  • Bluetooth BMS Monitoring — Real-time data via the LP Battery View app including SoC, time remaining, voltage, and temperature
  • BCI Group 31 Form Factor — Drop-in fit for standard marine Group 31 battery trays
  • Replaces Two AGM Batteries — One M31-24 delivers the equivalent output of two Group 31 lead-acid batteries
  • Up to 5x Faster Recharging — Accepts charge current significantly faster than lead-acid batteries
  • Over 5x Cycle Life — LiFePO4 chemistry provides dramatically longer service life vs. standard lead-acid
  • 96% Energy Efficiency — Converts input energy to stored energy at 96% efficiency vs. approximately 75% for lead acid
  • Sustained Voltage Under Load — Holds higher voltage while loaded for consistent trolling motor performance all day

The M31-24 is an ideal upgrade for bass boats, bay boats, flats skiffs, and pontoons where weight savings and runtime are critical. A 25.6V LiFePO4-compatible battery charger is required for proper charging.
