January 13, 2025: Battery developer Epsilor Electric Fuel is to unveil a new 4,400Wh/174Ah capacity lithium ion battery later this month targeting the military vehicles market.

Epsilor said on January 7 the new 25.2V battery, which it claims has an energy density six times higher than comparable lead acid batteries and 50% higher than any lithium competitor, will be presented at the International Armored Vehicles Conference at Farnborough, in the UK, from January 21-23.

The new NATO 6T battery, named ‘ELI-52526-GM’, is designed for use in defence vehicles and deployable defence systems. It will provide military users with extremely high energy capacity in a 28kg pack.

Rigorous testing of the product by US-based independent laboratories include bullet penetration, heat up to 500˚C, performance in cold and hot temperatures and long cycle life — part of the battery maker’s bid to obtain US army military performance specification compliance.

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.

Ronen Badichi, president of the AROTECH Energy Solutions Division and Epsilor’s general manager said the new battery had overcome “the major obstacle of the lithium battery safety issue.

“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.”
