The new battery, named ELI-52526-GM, offers the highest energy capacity in the market of 4,400Wh/174Ah,

Epsilor is part of the Michigan based AROTECH Corporation, which develops and manufactures advanced electronic subsystems for defence applications and simulation systems for aerospace and vehicle applications.

During the last year, Epsilor's COMBATT 6T batteries are undergoing rigorous tests by US based independent laboratories, as part of the company's certification campaign aiming to obtain the US ARMY Military Performance Specification Compliance (MIL-PRF-32565C - TYPE 2). The tests include bullet penetration, heat up to 500˚C, performance in cold and hot temperatures, long cycle life, communication with client's platforms and more.

The new battery is designed according to the same principles, aiming to meet the same requirements of the said MIL-PRF-32565C. Designed for use in military defence vehicles and deployable defence systems, the new battery will provide military users with extremely high energy capacity, of 4,400Wh in a 28kg pack, six times the energy of traditional Lead-Acid batteries with a similar 6T form factor and approximately 50% more energy than any other 6T Li-Ion battery.

During the last decade, Lithium 6T batteries have become common in a wide range of military vehicles and deployable systems, serving various applications, such as long silent-watch missions, energy regeneration, hybrid vehicle propulsion, robotics and UGV, plus auxiliary energy banks.

"With our new COMBATT battery we overcame the lithium battery safety issue, which is considered a major obstacle", said Ronen Badichi, President of the AROTECH Energy Solutions Division and Epsilor's General Manager. "By using a unique energy absorbing design, we are offering the highest energy capacity in the 6T category, while staying within the demanding safety and operational requirements of the US Army."
