Our Defense Sector Products Include:

Reusable Torpedoes, Targets, and Unmanned Underwater Vehicles

Today’s military technology requires advanced and innovative power solutions for everything from training torpedoes to unmanned underwater vehicles (UUVs). JKPower’s lithium ion and lithium polymer cells achieve unrivaled power density and pressure ratings for the next generation of training and combat operations. Our variety of available cells allow solutions that fit any application and enable lighter, faster, and more efficient submersible technology.

Soldier Portable Power

At JKPower we understand the last thing a soldier needs is to carry extra weight into combat, or find himself without power in the heat of a battle. With fast charging rates and reliability, our light-weight high-performance lithium ion cells provide the necessary power and energy density required for on-the-go tactical power that helps secure victory on the battlefield.

Uninterruptible Power Supplies

The modern military requires a wide range of vital computer and communications systems and these systems need reliable power sources. Whether on the sea, ground, or by air, uninterruptible power supply (UPS) systems are vital to military efforts. JKPower’s lithium battery cells provide reliability for tactical UPS systems day-in and day-out.
