Lithium Pros

<h3>About Lithium Pros</h3><p>Founded in 2011 and headquartered in Knoxville, Tennessee, Lithium Pros is not your typical battery company. The brand was built from the ground up by a team of genuine performance enthusiasts — competitors in drag racing, drifting, SPL audio, and off-road — alongside engineers, chemists, and machinists who understand exactly what it takes to deliver reliable energy in the most demanding environments on Earth. That hands-on expertise is baked into every product they make.</p><p>At the heart of Lithium Pros&apos; philosophy is a simple but powerful goal: bring the weight, power, and longevity advantages of advanced lithium-ion chemistry to the marine, racing, EV, fleet, and specialty markets. Where traditional lead-acid batteries are heavy, slow to charge, and quick to fade under load, Lithium Pros products are engineered to hold a higher voltage under load, recharge significantly faster, and last far longer cycle after cycle.</p><h3>Why Lithium-Ion Changes Everything</h3><p>The performance gap between lithium-ion and lead-acid chemistry is substantial. <strong>Lithium Pros&apos; LiFePO4 batteries deliver roughly three times the energy density</strong> of comparable lead-acid units, meaning you get more usable power in a dramatically smaller and lighter package. Some models are light enough to float — a remarkable feat that speaks directly to the weight savings serious racers and boaters demand. Faster recharging, longer cycle life, and higher charge efficiency round out a compelling case for making the switch.</p><p>The brand has earned a loyal following among professional anglers, competitive racers, and boating enthusiasts who depend on their equipment not to fail. <a href="/200366-engine-batteries-lithium-pros-18968">Engine batteries</a> capable of cranking the most powerful outboards on the water, deep-cycle <a href="/18968-lithium-pros-batteries-200137">batteries</a> engineered for trolling motors and fish finders, and purpose-built <a href="/18968-lithium-pros-battery-chargers-200141">battery chargers</a> designed specifically to work with lithium-ion chemistry — Lithium Pros covers the full ecosystem.</p><h3>Built for Racing, Proven on the Water</h3><p>Lithium Pros has a deep motorsports pedigree. The company has been trusted in SCCA World Challenge, Formula Atlantic, and drag racing applications for years, and that racing DNA directly influences the durability and performance characteristics of their marine and specialty products. Their charger lineup is assembled and tested in Tennessee, and the brand prides itself on offering real support from real people — a rarity in the battery space.</p><p>Whether you are replacing a heavy group 31 AGM battery on your bass boat, chasing tenths on the drag strip, or building out a fleet application that demands consistent reliability, Lithium Pros brings the same obsessive attention to energy performance across every product category.</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.
