New 450 Ah Lithium Battery

Leading-Edge 4.5 Ah Density Cell Technology

At Expion360, we're dedicated to meeting the diverse power demands of RV enthusiasts, overlanders, van builders, mariners, and off-grid enthusiasts. That's why we're thrilled to introduce our latest breakthrough - the e360 450 Ah battery, now fortified with our leading-edge 4.5 Ah density cells.

Our new 450 Ah battery boasts our groundbreaking 4.5 Ah UL1642 recognized stainless steel encased 26650 cylindrical cells. This ensures you get the highest power output with minimal added weight and size compared to the industry standard 3.4 Ah cell. The new 4.5 Ah cell means an impressive 32.35% increase in energy density in the same physical size. 

Rest assured, the e360 450 Ah battery is UL1973 compliant (TEi Listing Services, File no. 22D01), reinforcing our commitment to providing you with a safe and reliable power solution that exceeds expectations.

Dedicated to our Customers

We remain dedicated to customer choice and continuity. While we introduce the 450 Ah battery, we will continue to offer the previous 368 Ah version. This allows customers to choose the battery configuration that best suits their requirements, providing flexibility and convenience. 


Shipping of the new 450 Ah battery is slated to commence in the first quarter of 2024.
