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Pros was built by a team of engineers, chemists, and racing enthusiasts who shared a single obsession: replacing outdated lead-acid batteries with the most advanced lithium-ion technology available.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 M31-24CK is a complete 24V lithium-ion marine power kit designed for tournament and recreational anglers running 24V trolling motors. This kit pairs the M3175-24 — a 25.6V / 75Ah LiFePO4 (lithium iron phosphate) deep-cycle trolling battery — with the M1224 onboard DC charger, giving you everything needed to replace two conventional Group 31 lead-acid batteries with a single, dramatically lighter solution.

Key Features:

  • 25.6V / 75Ah LiFePO4 chemistry — stable, safe lithium iron phosphate cells for reliable deep-cycle performance
  • BCI Group 31 form factor — fits standard Group 31 marine battery trays with no modifications required
  • Bluetooth connectivity — monitor battery state via the Lithium Pros app
  • 138 reserve minutes — enough capacity to troll from daylight to dark on a single charge
  • Lightweight design — approximately 31 lbs, replacing two lead-acid batteries that can weigh 120+ lbs combined
  • M1224 onboard DC charger included — automatically recharges the trolling battery from the outboard engine's charging system underway
  • Transferrable 7-year warranty — industry-leading coverage from a USA-based manufacturer

The M3175-24 battery measures 13″ L × 6.81″ W × 8.43″ H, matching a standard Group 31 footprint for straightforward drop-in installation. The included M1224 DC charger taps into the outboard's alternator output to keep the lithium battery topped off while running, extending on-water range and eliminating the need to monitor battery levels throughout the day. A dedicated 25.6V LiFePO4-compatible shore charger is required for shore-side charging (sold separately).

Ideal for bass boats, flats boats, and saltwater tournament vessels where every pound matters, the M31-24CK delivers all-day trolling power in a package that dramatically reduces weight and improves boat performance.
