About Us


Navitas Systems LLC, a leader in comprehensive energy storage solutions, was formed in 2011 with the merger of MicroSun Innovative Energy Storage Solutions and MicroSun Electronics, and the acquisition of lithium battery company A123 Systems’ Government Solutions Group, located in Ann Arbor, Michigan.  In 2019, East Penn Manufacturing– one of the world’s leading battery manufacturers—acquired majority interest in Navitas Systems. 

Today, we engage in the research, design, development, and manufacture of advanced lithium cells and energy storage products and systems for both commercial customers and U.S. Government/military customers.

We produce both small and large format lithium batteries for a range of high power and high energy applications; battery management systems with custom hardware/firmware and communications; chargers and inverters; and power management systems. We offer customized packaging, including ruggedization to military or transportation standards; thermal management systems for extreme hot and cold conditions; and industry standards compliance. Navitas Systems has a full range of energy storage core competencies from advanced chemistries, electronics design, software development, printed circuit boards, mechanical packaging, system integration, cell and battery pack manufacturing, and test and evaluation.

Navitas Systems has both a 48,000 square foot R&D, Engineering, & Manufacturing Center, as well as a new 100,000 square-feet lithium battery pack Manufacturing Center. From advanced R&D, safe/high energy cell design, in-house battery testing, to sophisticated battery pack assembly, Navitas Systems is a premier source for comprehensive energy and power electronics solutions.


Customer Intimacy

We sit “on the same side of the table” as our customer. By not having an agenda to “push” a particular chemistry, we work collaboratively and together iterate on what’s the best solution. With that comes mutual trust, and the outcome is the best solution, time after time.

Value Innovation

Leverage the brainpower of the R&D scientists and battery engineers gained from our acquisition of the A123 Systems Government group—and combine that with our long-established relationships with that subset of best battery cell providers in the world—to create compelling, cost-effective, and highly differentiated solutions for our customers.

Speed with Accuracy

Because our company’s focus is on tough energy challenges, naturally our customers have an acute urgency. Our organization is architected to identify, design, and deliver the highest quality solution in the minimum amount of time, fulfilling our upfront commitments. The trust we’ve earned speeds commerce, and both our customers and our company win as a result.

Competitiveness, Quality, & Fiscal Sustainability

Invest in the infrastructure which ensures we’re designing, making, and testing our products for maximum performance, life, and safety. Earn a suitable return on our investments through fair-for-all pricing, enabling us to reinvest in the business and be there for our customers for the long-term.


I’d like to introduce you to one of the finest management teams in the industry. Through internal growth, strategic acquisitions and targeted recruiting, we’ve assembled a group of executives second to none in their knowledge of the energy storage and power electronics industries. All told, our management team alone approaches almost 200 years of collective experience in these two industries. People who have been “around the block”, know the fastest path to solutions, and have their own trusted networks of relationships. We look forward to adding you the visitor to this network of trust.
