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.

Your Expion 120 Ah lithium batteries are FABULOUS! We had plenty of power all summer using solar panels alone. They are so easy and simple to hook up and unhook. Thank you so much for helping us make the switch. Why does anyone use lead acid batteries anymore?!
