Epsilor Electric Fuel Ltd., a world-recognized developer and manufacturer of smart Li-Ion batteries and chargers, has completed the development of its new generation COMBATT 6T Li-Ion battery for military vehicles, offering the highest energy capacity in the market of 4,400 Wh/174 Ah. The new battery, named COMBATT ELI-52526-GM, will be presented at DSEI UK 2025 (September 9-12, Stand N11-104).
Designed for use in defense vehicles, deployable weapon systems, and naval applications, the new battery will provide military users with extremely high energy capacity, 4,400 Wh in a 27 kg pack, six times the energy density of traditional lead-acid batteries with a similar 6T form factor, and approximately 50% more energy than any other 6T lithium battery.
MIL-PRF-32565C Compliance
During the last year, Epsilor’s COMBATT 6T batteries have been undergoing rigorous tests by US-based 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.
“With our new COMBATT battery, we overcame the lithium battery safety issue, which is considered a significant challenge,” said Ronen Badichi, Epsilor President and 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 requirements of the US Army standard”.
