Battery Team Experience

We have key team members that have been active within the battery and battery-charger industry since 1996. Our battery team has more than 22 years of experience in military, medical, industrial, and high-volume consumer industries providing Epec a distinct advantage when developing and qualifying battery designs for use in these industries.

Epec's experience includes pioneering the development of custom safety circuits and battery chargers for the Li-sulfur chemistry. We have extensive experience in the development of safety-circuits, fuel gauging, and battery chargers for Li-ion, and Li-polymer chemistries. As a result, our team has received numerous patents in their area of work.

America's Oldest. A History of Innovation.

Today at Epec, the customer comes first, and everything we do must be put through that filter. Whether it is developing e-commerce platforms to make it easier to work with us, or creating a NPI (new product introduction) process that helps our customers get to market faster, or the other 10 new projects we have in process, we must focus on building the new. By doing that every day, and by always making the customer our top priority, we plan on being here for another 65 years and then some.
