Israel-based Epsilor Electric Fuel, which produces smart lithium-ion batteries, chargers and mobile power management systems for defense, transportation and other applications, has developed its COMBATT 6T Li-Ion battery for military vehicles.

The 25.2 V battery delivers 4,400 Wh and 174 Ah, demonstrating capacity that is six times higher than similar lead-acid batteries and 50% higher than other 6T lithium batteries, according to the company. Epsilor is part of Michigan-based defense and security company Arotech.

The 27 kg COMBATT ELI-52526-GM is designed for use in defense vehicles, deployable weapon systems and naval applications.

Epsilor offers a range of NATO standard 6T lithium batteries, optimized for various defense systems. They have undergone tests by US-based laboratories over the past year as part of the company’s certification campaign to obtain US Army Military Performance Specification Compliance (MIL-PRF-32565C – TYPE 2).

The tests include bullet penetration, heat tolerance up to 500° C, performance in high and low temperatures, long cycle life and communication with client platforms.

The series includes three variants:

• The COMBATT ELI-52526-DM/GM delivers 3.6-4.4 kWh and 144-174 Ah, complying with MIL-PRF-32565C (Type 2).
• The COMBATT ELP-02426-M uses an LFP chemistry. It offers 2.56 kWh and 100 Ah, which complies with the safety requirements of MIL-PRF-32565C (Type 1).
• The COMBATT ELI-52526-C delivers 4.2 kWh and 166 Ah, and is optimized for robotics, tactical energy storage and micro-grid applications.

“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.”
