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.

Our company is headquartered in Central Oregon, an area renowned for the great outdoors and pioneering spirit. It’s here that we pull inspiration for our reliable products that sustain the desire for adventure in beautiful, rugged places.

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.
