The Expion360 Difference 

Take your adventure further with Expion360 batteries and accessories. 

10x Life Cycle 

With tenfold the lifetime of your 100 Ah lithium battery investment, you can expect greater durability and reliability with E360. Our batteries are one of a handful to achieve UL 1973 compliance for optimal safety. 

3x Energy Density 

Our batteries use only the highest-grade lithium iron phosphate encased in steel and meet the UL1624 standard (UL file no. MH64383). Our reimagined cell packs allow you to power more appliances for longer with three times more energy density than traditional lead acid batteries.  

3x Faster Recovery 

Save time and go further with a faster overall charge time. And keep your investment going for years with Expion360’s “smart” BMS design with abundant safety features for trouble-free performance. 

50% Lighter 

We redesigned the traditional battery case to not only be 50% lighter but also more innovative. With built-in rubber feet, larger terminal connection pads, and the highest-grade ABS plastics, our design is built to lighten your load and power adventure.
