Expion360 Batteries
Expion360 LiFePO4 Batteries: Power Built for Adventure
When it comes to deep-cycle lithium power for RVs, marine vessels, and overland rigs, Expion360 has carved out a reputation for engineering that goes well beyond industry norms. Every battery in their lithium battery lineup is built around one core chemistry: LiFePO4 (Lithium Iron Phosphate). LiFePO4 chemistry is considered a top choice for high energy density, dependability, longevity, and safety — and Expion360 pushes this chemistry to its limits with proprietary cell technology, intelligent battery management, and thoughtful enclosure design.
Proprietary Cell Technology & Extreme Density
At the heart of every Expion360 battery are UL1642-recognized 3.4Ah stainless steel encased 26650 cylindrical cells, which offer superior mechanical stability and safety compared to prismatic pouches, ensuring the battery handles the vibrations of the road or water with ease. Their higher-tier models step it up further: the 162Ah GC2 battery utilizes UL1642-recognized 4.5Ah stainless steel encased 26650 cylindrical cells, delivering an impressive 32% increase in energy density compared to traditional 3.4Ah cells.
The flagship e360 Extreme Density line pushes this even further. The E360 368Ah (4,710Wh) deep cycle lithium battery is a one-of-a-kind model with the highest energy density in the Expion360 battery lineup. For the largest installs, the EX1 450Ah model represents the pinnacle: this single EX1 unit delivers a staggering 450Ah of capacity — equivalent to a massive bank of lead-acid batteries — in one compact, easy-to-install footprint.
VHC™ Internal Heating: Four-Season Confidence
One of Expion360's most notable innovations is their patent-pending VHC™ (Vertical Heat Conduction) technology. Most lithium batteries cannot be safely charged in the cold, but VHC™ changes the game — this proprietary internal heating system is specifically designed for cold-weather RV and overland use, automatically warming the cells to safe charging temperatures. The VHC™ system evenly warms the battery core, allowing safe charging in temperatures as low as -4°F.
SmartTalk™ Bluetooth Monitoring
Select Expion360 batteries feature integrated SmartTalk™ Bluetooth connectivity. Integrated Bluetooth technology syncs seamlessly with the Expion360 SmartTalk™ app, allowing users to monitor real-time voltage, current, temperature, and remaining capacity directly from a smartphone without needing a separate monitor. Wireless fleet management even allows users to name and track multiple batteries individually within the app to pinpoint issues instantly.
Safety Standards & Long Cycle Life
Every Expion360 battery in this lineup carries UL1973 compliance — one of the most rigorous certifications in the energy storage industry. UL1973 is one of the most rigorous safety standards for energy storage systems; achieving compliance means battery packs have passed extensive testing for resistance to abuse — including overcharging, short-circuiting, and fire exposure — meeting stricter requirements for insurance and marine regulations that non-compliant batteries cannot pass. As for longevity, Expion360 batteries are rated for 5,000+ cycles at 80% depth of discharge, which for the average user translates to 10–15 years of service life.
Drop-In Sizing & Scalable Systems
Expion360 batteries come in standard BCI group sizes — including Group 24, Group 27, GC2, and the proprietary EX1/EX2 Edge formats — making them straightforward replacements for existing lead-acid setups. Featuring standard BCI group sizing for a direct drop-in fit and integrated CAN Bus communication, these batteries are built to grow with your needs and can be networked in series or parallel to power heavy-duty inverters and sophisticated off-grid electronics.
All of this engineering is designed and engineered in Central Oregon, built to exceed safety standards, making them the trusted choice for remote travel and mission-critical off-grid power. Backed by an industry-leading 12-year warranty and UL1973 compliance , Expion360 batteries represent a serious long-term investment for anyone demanding reliable, high-density power away from the grid.
