<h3>RELiON Battery: Redefining Lithium Power for Every Adventure</h3><p><strong>RELiON Battery</strong> was founded in 2014 with a singular focus: bring lithium iron phosphate (LiFePO4) battery technology to everyday adventurers, boaters, golfers, and off-grid enthusiasts who deserve a better power source. Headquartered in Menomonee Falls, Wisconsin, RELiON has grown into one of the most trusted names in the lithium battery industry, now operating as part of the Navico Group — one of the world's largest providers of marine, RV, and specialty vehicle technologies.</p><p>What sets RELiON apart from conventional battery makers is an unwavering commitment to LiFePO4 chemistry. Unlike traditional lead-acid batteries, RELiON&apos;s lithium iron phosphate cells deliver significantly more usable energy at a fraction of the weight, with zero maintenance requirements. Whether you&apos;re boondocking in the desert, running electronics on a fishing boat, or keeping a golf cart running all day, RELiON&apos;s lineup of <a href="/16155-relion-batteries-200137">batteries</a> is engineered to outperform and outlast the alternatives.</p><h3>Built-In Intelligence: The InSight Series</h3><p>RELiON&apos;s InSight Series&trade; represents the brand&apos;s most advanced engineering. Launched in 2019, it introduced the first scalable GC2 drop-in lithium replacement for golf cars, low-speed vehicles (LSVs), and utility vehicles — requiring no tray modifications whatsoever. The InSight Series features a proprietary Battery Management System (BMS) with intelligent software that auto-balances cells, manages regenerative currents, and protects against over-charge, over-discharge, over-temperature, and short-circuit conditions. Select models even include a patented internal heating element for safe cold-weather charging in sub-zero temperatures.</p><p>For RV and marine users, the InSight 12V is a deep-cycle powerhouse designed to help travelers disconnect further from the grid, powering electronics longer and reducing reliance on shore power. RELiON&apos;s vehicle batteries span 12V, 24V, 36V, and 48V configurations, making them compatible with a broad range of platforms from Class A motorhomes to pontoon boats.</p><h3>Safety, Certification, and Manufacturing Excellence</h3><p>Every RELiON battery is built to rigorous standards. The company&apos;s factory holds ISO 9001 certification, and all lithium batteries are UN38.3 certified for transport safety. Each unit undergoes extensive quality assurance checks before it ships. RELiON&apos;s LiFePO4 chemistry is inherently more thermally stable than other lithium chemistries, and the addition of high-temperature thermal fuses, flame-retardant materials, and pressure relief systems adds further layers of protection.</p><p>The results speak for themselves: RELiON batteries are capable of up to thousands of charge cycles at full depth of discharge — delivering years of reliable service that traditional lead-acid batteries simply cannot match. RELiON&apos;s RB36V40 marine battery even earned a 2024 Top Product Award from <em>Boating Industry Magazine</em>, recognizing its innovative parallel design and IP67-rated waterproof casing.</p><h3>Powering a Community of Adventurers</h3><p>RELiON takes genuine pride in the community of customers it serves — from weekend campers and full-time RVers to competitive anglers and golf course fleet managers. The brand actively listens to user feedback to refine and expand its product lineup, ensuring that each new release addresses real-world challenges. With U.S.-based technical support and one of the largest LiFePO4 product portfolios available, RELiON continues to push the boundaries of what lithium energy storage can do for the people who depend on it most.</p>

Product Details

The Relion RB80 is a high-performance lithium iron phosphate (LiFePO4) battery that delivers exceptional power in a lightweight, compact package. Designed for marine, RV, and off-grid applications, this 12-volt, 80 amp-hour battery offers superior energy density and reliability compared to traditional lead-acid batteries.

Key Features:

  • Group 27 form factor for easy drop-in replacement of lead-acid batteries
  • Weighs approximately 26 pounds—over 60% lighter than comparable lead-acid batteries
  • Delivers 80 amp-hours of consistent power with flat discharge curve
  • 3,000+ cycle life at 80% depth of discharge for years of reliable service
  • Built-in Battery Management System (BMS) protects against overcharge, over-discharge, and short circuit
  • Operates efficiently in temperatures from -4°F to 140°F (-20°C to 60°C)
  • Fast recharge capability accepts high charge currents
  • Maintenance-free design with no watering, equalizing, or off-gassing
  • Can be installed in any orientation without performance loss
  • Safe, stable LiFePO4 chemistry with no risk of thermal runaway

The RB80 is ideal for trolling motors, house banks, solar energy storage, and other deep-cycle applications where weight savings and long service life are critical. Its advanced BMS ensures optimal performance and safety, while the maintenance-free design eliminates the hassles associated with flooded lead-acid batteries.
