<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 RB100 is a premium 12V 100Ah lithium iron phosphate (LiFePO4) deep cycle battery that delivers exceptional performance for RV, marine, solar, and off-grid applications. This Group 31 battery is a direct drop-in replacement for traditional lead-acid, AGM, or GEL batteries, offering superior power and reliability in a compact, lightweight package.

Key Features:

  • Lightweight Design: At only 30 lbs, the RB100 weighs 50-60% less than equivalent lead-acid batteries, improving fuel efficiency and handling
  • Ultra-Long Lifespan: Provides up to 10 times longer life than lead-acid, maintaining 80% capacity after 2,000 cycles at 100% depth of discharge
  • Built-in Battery Management System (BMS): Ensures safe operation, accurate state of charge calculations, and protection against overcharge, over-discharge, and short circuits
  • Fast Charging: Charges in as little as 1-2 hours with proper equipment, significantly faster than lead-acid alternatives
  • 100% Usable Capacity: Unlike lead-acid batteries limited to 50% depth of discharge, lithium delivers full rated capacity without degrading performance
  • Temperature Tolerant: Operates efficiently from freezing temperatures up to 149°F (65°C), with 2.5x better low-temperature performance than lead-acid
  • Maintenance-Free: No watering, no corrosion, and low self-discharge means the battery is always ready when you need it
  • IP67 Rated Protection: Completely dust-proof and water-resistant for up to 30 minutes at 1 meter depth
  • Series/Parallel Compatible: Can be wired in series or parallel configurations for increased voltage or capacity

Specifications: 12.8V nominal voltage, 100Ah capacity, 1280Wh energy, M8 threaded stud terminals, ABS case construction. UL, UN, CE, and IEC certified for safety and reliability.

The RB100 surpasses expectations by being versatile, compact, and more powerful than lead-acid counterparts, making it the perfect combination of size and capacity for recreational and commercial applications alike.
