Why Choose Expion360? A Look Inside.
Smart BMS (Battery Management System)
Our proprietary "Smart" BMS protects your investment. It features low-temp discharge and auto-shutoff for cold weather performance, alongside high/low voltage shutoffs, short-circuit protection, and overcurrent disconnects. The BMS is structurally bolted to the pack with an oversized heatsink for years of trouble-free operation.
Robust Case Design
We are the first in the industry to integrate rubber feet directly into the case, eliminating vibration and sliding. The case is crafted from fiberglass-infused ABS plastic (meeting UL 94V-0 fire retardant ratings) with radiused corners for structural strength.
Superior Power Transfer
We eliminated fragile solder points. Our cells are welded via thick copper machined collector plates, creating a mechanical backbone that reduces resistance and heat buildup. Our terminal pads are 96.7% larger than standard terminals, featuring opposing connection points for flexible mounting and reduced cross-polarity risks.
Industry-Leading 12-Year Warranty
Buying lithium is an investment in your freedom. We back that investment with a 12-year warranty—one of the best in the business. Combined with our U.S.-based customer support team trained specifically in lithium technology, you can explore with total confidence.
FAQs
No, you should not mix chemistries. Lithium batteries have different voltage curves and charging requirements. For the best performance, replace your entire bank with Expion360 LiFePO4.
While our batteries can work with many standard chargers, we recommend a charger with a specific Lithium (LiFePO4) profile to ensure you get a 100% full charge and balance the cells properly.
Lithium batteries cannot accept a charge below freezing (32°F) without damage. Our VHC™ technology uses internal heating pads to warm the battery cells automatically, allowing you to charge safely even in winter conditions.
Expion360 batteries are rated for 5,000+ cycles at 80% depth of discharge. For the average user, this translates to 10–15 years of service life.
UL 1973 is one of the most rigorous safety standards for energy storage systems. Achieving this compliance means our battery packs have passed extensive testing for resistance to abuse—including overcharging, short-circuiting, and fire exposure. For you, this means verified safety for your family and your rig, often meeting stricter requirements for insurance and marine regulations that non-compliant batteries cannot pass.
While UL 1973 covers the entire battery pack, UL 1642 focuses specifically on the individual lithium cells inside. Using UL 1642 recognized cells ensures that the foundational building blocks of our batteries have been independently tested for stability and safety. We don't cut corners; we build our packs using only top-tier, certified cells to ensure maximum longevity and reliability.
