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Pros was built by a team of engineers, chemists, and racing enthusiasts who shared a single obsession: replacing outdated lead-acid batteries with the most advanced lithium-ion technology available.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 M3167-36 is a high-performance 36V 67Ah (2,570 Whr) lithium iron phosphate (LiFePO4) trolling battery designed for serious freshwater and saltwater tournament anglers. This advanced marine battery replaces three Group 31 AGM batteries with a single, lightweight unit that delivers exceptional power and endurance for 36V trolling motor applications.

Key Specifications:

  • Voltage: 38.4V (36V nominal)
  • Capacity: 67Ah (2,570 watt-hours)
  • Reserve Minutes: 160
  • Weight: 39.8 lbs (vs. 231 lbs for three Group 31 lead-acid batteries)
  • Dimensions: 13" L x 6.81" W x 8.43" H (BCI Group 31 size)
  • Chemistry: Lithium Iron Phosphate (LiFePO4)
  • Water Resistance: IP67 rated

Performance Features:

  • Three times the energy density of comparable lead-acid batteries
  • Maintains higher voltage under load for consistent trolling motor performance
  • Recharges up to five times faster than lead-acid batteries
  • Over 2,500 charge cycles at 80% depth of discharge
  • 96% charge efficiency versus approximately 75% for lead-acid
  • Cold-weather functionality for year-round fishing

Built-In Protection:

  • Internal battery management system (BMS)
  • Over-temperature protection
  • Over-voltage and under-voltage protection
  • Over-current and short-circuit protection
  • Automatic cell balancing

The M3167-36 fits standard Group 31 battery trays, making installation quick and straightforward. Compatible with on-board DC chargers for automatic recharging from your outboard engine's charging system or systems like PowerPole CHARGE. This battery provides enough power for all-day trolling from daylight to dark, eliminating the need to manage multiple batteries.

Important Note: A 38.4V LiFePO4 compatible battery charger is required (sold separately). Not intended for engine starting or alternator charging applications.

Great! Equal to any

Well-designed website and search, prices and checkout experience was nice.

Quick

Shipping cost was too high for the length of time it took to be delivered.
