Why Our Marine Lithium Batteries Keep You On The Water Longer

Marine recreation can be highly unpredictable. When a storm system rolls in and the tides change, you need reliable and consistent power. Marine lithium batteries consistently perform to the highest caliber in extreme conditions. Whether you cast your line on a lake, river, or ocean, we’re detailing how our E360 batteries keep you on the water longer.  

Marine Lithium Batteries Made to Last 

Traditional boat batteries are heavy and clunky—not adjectives conducive to a smooth boating experience. Compared to lead-acid, marine lithium batteries are made to support various boating needs, whether you’re outfitting trolling motors or installing a battery to operate your cabin electronics. At Expion360, we design and engineer our batteries to withstand the harshest marine conditions with power and efficiency. 

To keep you on the water longer, we’ve given our batteries the following features: 

50% Lighter

One of the most crucial considerations when choosing marine lithium batteries is weight. We engineered our batteries to be half the weight of traditional lead acid batteries for optimal efficiency, performance, and speed. 

3x More Energy Dense

Our batteries punch above their weight class when it comes to energy efficiency. To achieve this, we’ve reimagined lithium battery design from the inside out. The combination of cells welded with thick copper/tin machined collector plates, mechanical backbones for the BMS, and high-grade wiring and ring terminals throughout gives our batteries three times the energy density. 

10x the Life Cycle 

Remember that part about keeping you on the water longer? Expion360 lithium batteries have ten times the lifecycle. That means tenfold the lifetime of your battery investment and more days doing what you love out on the water. 

3x the Recovery 

A recharge doesn’t have to stop your entire day. With three times the recovery, you can charge faster, save time, and move further. 


When you’re on the water, these details can be the difference between a good day and a bad one.

Backed By Leading Warranty and Support 

In addition to a reimagined battery, we’re also leading the charge on warranty and support. Because we know batteries are an investment into your pursuits—on and off the water—we provide a 12-year true warranty for ultimate peace of mind. 

When in need, our U.S.-based customer support team—trained in lithium technology—can troubleshoot and answer any questions. With this warranty and support, we’re fully backing up our products and customers.
