Intelligently Flexible Lithium Marine Batteries

Our lithium ion boat battery was created with flexibility in mind. Every application is unique. That’s why we developed our batteries to provide the flexibility your project requires, providing you with an energy storage solution that is designed with your specific needs in mind. Lithium ion batteries can have a long life if properly designed. We are dedicated to creating maximum capacity battery systems with the capability of powering any project.

Trident's batteries are interconnected at the front of the module rather than the back of the rack as seen in many competitive systems. This permits Spear to configure the battery so that it completely fills available spaces. The unique advantage of this approach is that Spear is able to fit up to 40% more energy in the same footprint.

Safety - First and Always

Beyond providing consistent power, we understand the requirements of a battery protection system that is safe. The Trident Scalable Battery Management System (SBMS) features advanced, highly redundant safety systems which prevent abuse of the battery that would lead to unsafe conditions. In the unlikely event of an issue with the cell, Spear prevents propagation of a fire from one cell to another, greatly limiting the scale and impact of a thermal event.

Thermal Management Technology

Trident is uniquely available in both liquid and air-cooled formats with the same footprint and type approval. Spear is the only marine battery vendor who can suggest a cooling method without implicit bias. Customers can trust Spear to recommend the thermal management approach that makes the most sense for their vessel.
