About Spear Power Systems

Spear Power Systems stands at the forefront of radically safe and innovative lithium-ion battery storage systems for a range of demanding applications – whether on land, at sea, or in the air. With decades of experience in cell and battery systems manufacturing as well as a dedication to providing the optimal solution to each customer, Spear brings a team of expert engineers, scientists, and project managers to your application.

The History of Spear Power Systems

In 2005, Jeff Kostos and Dr. Joon Kim launched Kokam America. Kokam America was established to bring lithium-ion cell technology to the United States, and that goal was realized as the first cell manufacturing facility opened in 2008. After continued growth and additional partnership with Dow Chemical, the pair formed Spear Power Systems in 2013. Since that time, Spear has developed powerful new battery storage solutions and battery pack integration techniques and technologies.

Energy Storage Solutions for Aircraft, Maritime, and Industrial Applications

Spear has a wide range of energy storage systems suited to meet any demand. Our family of Trident maritime batteries offers multiple cell chemistries in order to provide you with industry-leading energy density or ultra-high power density depending on the requirements of your application.

Our Chemistry-Independent Approach to Cell Selection

Spear takes a chemistry independent approach to cell selection in order to ensure that your project uses the best cell for your needs. While some other battery manufacturers push only the cell chemistries that they create, Spear is able to leverage their experience in cell production to identify the best fit and secure those cells from a conglomerate of reliable cell manufacturers for the best price point. After selecting the optimal cell chemistry for your application needs, Spear’s team designs your solution to meet your space and weight requirements with unmatched efficiency. Where our competitors have designed a standard module that is difficult to alter, Spear’s battery modules are able to be adjusted to your requirements without compromising battery performance.

Spear also works closely with you to ensure that your application is unfailingly safe. Utilizing a novel in-house design, the Spear battery management system (BMS) monitors the status of your application to notify you if any aspect of your application’s performance is out of the norm. In addition to advanced monitoring, the BMS has numerous failsafe measures in place to identify and lock down any problems before they can cascade throughout the system. Spear has even designed a system that is able to quarantine a failing cell and prevent thermal runaway from propagating to adjacent cells.
