World’s most powerful military battery with 4,400Wh to launch in UK

Epsilor Electric Fuel Ltd., a leading manufacturer of advanced lithium-ion batteries, has unveiled the world’s most powerful military battery, the COMBATT 6T, capable of delivering 4,400 watt-hours (Wh) of energy in a compact NATO 6T form factor. Weighing approximately 59 lbs (27 kg), the ELI-52526-GM battery offers 174 ampere-hours at 25.2 volts and achieves an energy density exceeding 157 Wh/kg. Designed specifically for military vehicles and deployable defense systems, it provides six times the energy density of conventional batteries in the same form factor and about 60% more energy than any other Li-ion 6T battery currently available. This breakthrough positions it as a game-changing solution for next-generation defense systems requiring compact, high-performance, and mission-resilient power sources. A key innovation of the COMBATT battery lies in its proprietary energy-absorbing design, which enables it to withstand thermal and
