Spear’s lithium batteries are made to withstand the grittiest commercial situations without failing. You need your lithium ion marine battery to meet power demands, whether you are operating a cruise ship or a cargo vessel. A cost-effective battery you can trust to handle the load—that’s what you get with Spear’s marine batteries.


Clean energy is the technology of the future, but Spear has this energy technology today. Our battery systems offer a sustainable alternative power source to energy options that pollute and damage our environment. If you care about clean energy, then our power systems are the ones you should trust.


An energy storage system isn’t worth much if it’s not safe to use. That’s why Spear designed a battery that is as safe as possible while still giving you the powerful energy you need to propel your marine vessel.


If you are wondering if Spear’s lithium ion boat battery is flexible enough to suit your application, take a look at the case studies below to see where our lithium-ion batteries are currently in operation. Our marine batteries can handle any load because they are adjustable to suit your application’s energy needs. You can reduce fuel consumption, for cleaner, safer energy.

Case Studies of Our Marine Battery Systems in Action

Spear’s marine batteries are the best in the industry, but you don’t have to take our word for it. Our marine battery line is designed with maritime conditions in mind, and we can show you firsthand how our custom power solutions are put to use. We use innovative battery technology combined with creative solutions to meet the energy storage needs of marine industry professionals while hurdling the challenges of unique applications. Our batteries are developed to be user-friendly, and we’ve enhanced durability to ensure they meet the toughest conditions in the marine environment.

Here are a few examples of challenges we’ve overcome due to the significant advantages in the design and application of Spear’s Trident line of batteries.

Wind of Change

We provided an immensely efficient electrical system using Trident's liquid-cooled battery system paired with ABB's OnBoard DC GridTM. Louis Dreyfus Armateurs launched this advanced windfarm service operation vessel in 2019 and Spear provided power to a second sister vessel "Wind of Hope" which launched in 2021.

Gee's Bend Ferry

Back in the states, Spear technology is powering the Alabama-based Gee's Bend Ferry, the nation's first electric ferry. In 2019, this passenger ferry—capable of carrying 132 passengers—was retrofitted to be fully-electric. In 2020, Spear made its silver screen debut as the Ferry was featured on the Science Channel's series, "Sea Giants." 

Maid of the Mist

Spear Power Systems provided the high-capacity batteries that power the electric ferries at Niagara Falls. These new vessels provide a smoother, quieter experience for the thousands of tourists while generating zero emissions—preserving the natural beauty for future generations to experience.
