Boat batteries aren’t one-size-fits-all, and neither are your boating needs. Whether you’re outfitting trolling motors or installing a lithium battery to operate your cabin electronics, you need something that can withstand marine conditions with power and efficiency.
Whereas traditional lead acid boat batteries can be heavy and clunky, our lithium marine batteries are 50% lighter, three times more energy dense, and have ten times the life cycle. In addition, 3x faster recovery means you can charge faster, save time, and move further. On the water, that can be the difference between a good day and a bad one. There’s no doubt that these batteries are built for the long haul.

Complete Turn-Key Power Solutions
Expion360 lithium batteries feature fiberglass-infused ABS casings, solid mechanical connections, and waterproof components, ensuring long-lasting durability in saltwater and freshwater conditions.
Our lithium batteries are up to 50% lighter than traditional lead-acid batteries, reducing the overall weight of your vessel
and improving fuel efficiency and handling.
Charge your batteries 5X faster than lead-acid alternatives while enjoying a longer lifespan with up to 10X more cycles,
ensuring reliable power for years to come.
Stay in control of your boat’s power system with real-time battery data from the e360 SmartTalk™ app (available for iOS and Android), monitoring charge levels, battery health, and temperature.
Whether you're running refrigerators, navigation electronics, fish finders, or live wells, Expion360 lithium batteries deliver consistent, reliable energy for all your marine needs.
Our VHC™ (Vertical Heat Conduction) technology ensures optimal power output even in freezing conditions, perfect for year-round marine adventures.
Expion360 lithium batteries meet UL1973 safety standards, ensuring the highest level of protection and compliance for marine energy storage.
We use only the highest-grade lithium iron phosphate encased in steel and meeting theUL1642 standard(UL file no. MH64383). This material and engineering make for unparalleled reliability, stability, and safety.
We took the standard battery case up a notch with built-in rubber feet, radiused corners, 96.7% larger terminal connection pads, interior molded ribs for structural security, and the highest-grade ABS plastics with additives for fire retardancy. Our innovative case design changes the scope of the industry.
To keep our batteries as powerful and efficient as possible, we’ve welded our cells via thick copper/tin machined collector plates, welded all interior pack points, added a press broke flange at each end to create a mechanical backbone for the BMS, used high-grade wiring and ring terminals throughout, and treated connections with industrial epoxy for long-lasting protection.
Our “smart” BMS design has abundant features to provide you with the safety and performance you desire, such as: low-temp discharge, auto-shutoff, short circuit protection, low and high-voltage shutoffs, and overcurrent disconnect. Our structurally sound BMS board features a bolted design, eliminating all unnecessary solder, resulting in one cohesive pack for years of trouble-free performance.
Expion360 lithium batteries are held to the highest safety standards. Because of this, we are one of a small handful of companies to achieve a UL 1973 compliance
