Expion360 Story


Since John Yozamp founded the company in 2016, Expion360 has designed and engineered best-in-class lithium battery solutions across industries. Our customers are weekend adventurers seeking out the next great destination from a van or RV, off-the-grid homeowners getting away from it all, and recreational marine-going enthusiasts. To power the pursuit—whatever it may be—we knew we needed to develop a powerful battery that was safer, more efficient, and built for the long run. 

chase the next big thing

With more than ten years of experience in both the RV and solar industries, we became the industry leader for lithium batteries and accessories. Our products are built for tenfold the lifetime of your battery investment, three times the energy density, three times faster recovery, and an innovative case design.

At Expion360, we perform to the highest standards—and make sure our products do, too—so our customers can always chase the next big thing.

Expion360 Ambassadors

Team Overland

Team Overland was founded in 2015 with a simple mission to help Veterans reintegrate back into their communities when they return home. To accomplish this, they facilitate free guided overland adventures all over the Pacific Northwest. Their trips range from quick single-night adventures in the Cascades to week-long multi-state expeditions. Team Overland is a 100% volunteer-run organization with every board member, trail guide, and volunteer giving their time and resources to make their trips successful.
