A Story Of Passion and Pursuit
Expion360 started from a passion for batteries and premium engineering. But it also began with a passion for adventure. We knew performance was key from cross-country RV trips to deep sea fishing. So, we asked ourselves: what if we could build the lithium battery better? If we made it lighter, more durable, and gave it ten times the life and three times the energy (compared to a traditional lead acid battery)?
The answer:
E360 batteries to power the pursuit.
