RELiON Vehicle Batteries: Lithium Iron Phosphate Power Built for the Road

When it comes to powering vehicles — from overland rigs and camper vans to golf carts, utility vehicles, and specialty transport — RELiON has carved out a well-earned reputation as a leader in lithium iron phosphate (LiFePO4) energy storage. Founded in 2014, RELiON Battery is a global innovator in lithium battery technology and energy storage solutions. Today, RELiON Battery is part of Navico Group, a division of Brunswick Corporation, the world's leading supplier of integrated systems and products for marine, RV, specialty vehicles, and beyond.

Why LiFePO4 Is a Game-Changer for Vehicle Applications

Not all vehicle batteries are created equal, and RELiON's approach starts with chemistry. Built with lithium iron phosphate (LiFePO4), RELiON batteries offer the safest, most stable chemistry available — no risk of thermal runaway or dangerous leaks. That inherent stability makes them especially well-suited for vehicle use, where vibration, heat, and demanding discharge cycles are everyday realities.

RELiON lithium batteries are up to 50% lighter than lead-acid batteries, making travel easier and more efficient. For vehicles where every pound matters — whether you're maximizing range on a utility vehicle or reducing tongue weight on a tow — that weight savings translates directly to real-world performance. RELiON lithium batteries have super low resistance, allowing for much faster charging, and are 99% efficient — compared to traditional lead-acid batteries at just 75–80% efficiency.

InSight Series: Intelligent Drop-In Replacement

One of RELiON's flagship product lines for vehicle applications is the InSight Series. InSight is the first scalable LiFePO4 drop-in replacement battery requiring no extra hardware when connected in parallel, making it easy to increase available capacity for longer runtimes. InSight also features a SuperSmart BMS that allows for Bullseye Balancing™ through innovative algorithms ensuring precise balancing between cells. This intelligent system eliminates the guesswork from battery management and maximizes usable capacity over the life of the pack.

Longevity and Low Maintenance

A key reason vehicle owners make the switch to RELiON is cycle life. RELiON lithium batteries provide up to 10 times longer life than lead-acid batteries, and they still provide 80% of rated capacity after 2,000 cycles. Partial charging does not affect performance quality or battery life, and a low self-discharge rate means worry-free storage — so even occasional users can count on reliable performance. There's no watering, no acid spills, and no equalization charges required.

RELiON lithium batteries also include exclusive safety measures, such as a state-of-the-art battery management system (BMS) that protects against over-charge, over-discharge, over-temperature, and short circuit conditions. For vehicles operating in harsh or remote environments, that built-in protection is not just convenient — it's essential.

Built for Overland, Utility, and Specialty Vehicles

RELiON lithium batteries deliver reliable, long-lasting power for overland vehicles, from off-road trucks to camper vans — designed for rugged terrain and remote travel. Their batteries are also built to meet the power and energy requirements in golf cars, utility vehicles, and AGVs. RELiON boasts one of the largest lines of 12V, 24V, 36V, and 48V lithium battery systems in the industry, making it straightforward to find the right voltage for virtually any vehicle platform.
