Green Cubes Technology Appoints Power Industry Veteran as Chief Operating Officer

KOKOMO, INDIANA July 21, 2021 – Green Cubes Technology (Green Cubes), the leader in producing Lithium-ion (Li-ion) power systems that facilitate the transition from lead acid batteries and Internal Combustion Engine (ICE) power to green Li-ion battery power, appointed Ken Johnson as Chief Operating Officer (COO) for the company. Mr. Johnson reports to Keith Washington, President and CEO of Green Cubes, supporting all business units and operations.

Mr. Johnson provides leadership to supply chain, operations, and manufacturing roles to build processes for continued growth for Green Cubes within Telecom, Materials Handling, and Industrial Automation markets.  Mr. Johnson will manage Green Cube’s production facilities in Malaysia, Slovakia, Kokomo (Indiana), and Dunlap (Tennessee).

“Ken has led both domestic and international operations and supply chains through new product introduction, lean transformations, inventory reductions and overall working capital improvement,” said Mr. Washington. “I am confident his experience and focused vision will help Green Cubes successfully execute its continued growth within strategic markets and geographic locations.”

Mr. Johnson has a history of success in energy storage and power electronics technology as an operations leader with a demonstrated track record of success in these markets, spending over 25 years in global manufacturing and supply chain with companies such as IBM, Danaher, Eaton and Active Power.  The range of products manufactured under Mr. Johnson’s supervision includes personal computers, motors, DC power systems and single phase/three phase complex Uninterruptable Power System (UPS).   Mr. Johnson graduated with a Bachelor of Science and Master of Engineering degree from Texas A&M in Industrial Engineering.

Design World: MultiVoltage Lithium Batteries Target Material Handling Equipment

Patent-pending MultiVoltage technology enables the battery to charge at double its output voltage, which cuts charging time in half and makes opportunity charging a more accessible option with simplicity and ease of use for the operator.

Patent-pending MultiVoltage technology enables charging at double the batteries’ output voltage, halving the charge time and increasing productivity. Applicable to the material handling market, Green Cubes Technology’s MultiVoltage battery completes a full charge in less than one hour and is offered in 24/48 V, 36/72 V, and 48/96 V combinations.

Green Cubes has deployed over 200 MultiVoltage batteries across these three different voltage combinations. It is common for high use and high capacity batteries, such as a large 48-V battery, to be charged with two cables to increase the charge current. The MultiVoltage battery utilizes single connector 4/0 cabling in a charge port configuration, which delivers cost efficiencies and minimizes the chance of cable damage over traditional fast charging with dual cables. In addition, due to the lower insertion and extraction forces of the single connector equipment, operators appreciate the MultiVoltage systems over their dual cable counterparts.

“The ability to opportunity charge is a key feature of Li-ion batteries’ value proposition for material handling equipment,” said Anthony Cooper, General Manager of Green Cubes’ Motive Group. “MultiVoltage SAFEFlex batteries accommodate an even faster charging time which widens the performance gap between Li-ion and Lead Acid Batteries. Our class 2, 36-V products, have been extremely popular for Reach Trucks because they are very highly utilized and recognize the benefits.”

Other than the battery configuration itself, the MultiVoltage battery uses standard chargers and requires no changes to the equipment. Lithium SAFEFlex is the integration of lithium-iron=phosphate cells, electronics, packaging, and a software platform that was designed specifically for the rugged requirements of material handling. The advanced mechanical packaging meets the impact forces of a large forklift and the rugged automotive-grade Battery Management System (BMS) makes Lithium SAFEFlex the most reliable lithium battery for the material handling industry. With MultiVoltage technology, a quick coffee or lunch break can be used to charge a battery, keeping material handling equipment in full utilization.

No Compromises – When It Absolutely Must Work


At Green Cubes (formerly branded as UNIPOWER), we hang our hats on our reliability and robust designs. The following article comes directly from the field where we support the U.S. military and their communications equipment. Read how our Sageon DC power systems are the de facto standard for our military customers because reliability matters most of all. The post is from someone who really knows the need for reliability firsthand, and he is one of our partners – Michael Shillinger, a retired Army Lieutenant Colonel!


Working with governmental agencies such as the FAA and major defense contractors for the military, there is no room for compromise – especially when it comes to powering sensitive electronic and communications equipment. Due to their criticality and cannot-fail requirements, D.C. power systems must work the first time, every time. In partnering with the Krydon Group, our Sageon systems are being deployed in installations across the globe and often in very remote locations to solve complex challenges for critical government infrastructure at:

  • forward-deployed bases
  • domestic facilities
  • air traffic control facilities
  • mobile communication facilities

For most applications, the government looks for tried-and-true equipment with a long-proven track record of reliability, like our Sageon DC Power Systems and battery chargers made in Dunlap, Tennessee. For example, working with the Army often requires power solutions that are precisely customized with redundancy and the highest level of reliability (backed by ISO9001 Certification). Krydon’s dedicated team of technicians and engineers oversees the installation, validation, and load testing in theater to ensure all systems are functioning to spec.

“The Army, Navy, Air Force, Coast Guard and other agencies all know that the Green Cubes Sageon Systems and associated batteries are rock solid,” noted Michael F. Shillinger, vice president of engineering for the Krydon Group. As a retired Lieutenant Colonel from the U.S. Army and a veteran of Afghanistan and Iraq, Shillinger knows firsthand how critical it is to have the equipment – especially communications systems – always at the ready. On the rare occasion a question occurs, the folks at Krydon and Green Cubes are available to take the call at any hour of the day to quickly address any challenge.

Qualified for the “Buy American Act” program, GSA Advantage! and DoD projects, our Sageon family of DC Power Systems offer hot-swap rectifiers with 90% plus efficiency, battery monitoring and testing, and a wide operating temperature range from 40ºF to 158ºF. In addition, Green Cube’s ARE-M Battery Chargers offer 24V to 250V output, minimal maintenance, remote communications, temperature compensation and more.

For military installations, customization of our systems is a must to address specific form factors. Power shelves, power distribution components, enclosures, wiring, and other components are built or sourced to meet tight specifications. Training in theater is another key aspect of the Green Cubes-Krydon team. Setting up the power systems properly and fully understanding D.C. equipment operation requires experience with both the equipment and the highly specialized applications in which they are deployed.

We are proud to work with the Krydon Group (a member of the Society of American Military Engineers and the Armed Forces Communications-Electronics Association (AFCEA) to integrate and support our power systems for mission-critical defense programs.
