ESI Motion’s SatBat is an innovative satellite battery engineered to meet the rigorous demands of all space orbits. Optimized for high-cycle life, SatBat delivers groundbreaking performance compared to space-rated lithium-ion (Li-ion) batteries.

Featuring advanced thermal regulation and enabling 100% depth of discharge (DoD) per cycle without performance degradation, SatBat effectively doubles both mission life and usable capacity when compared to conventional alternatives.

Weighing in at half the mass of comparable space-rated Li-ion batteries, SatBat’s compact and lightweight design reduces payload strain and significantly lowers launch costs—where every saved kilogram represents an average savings of $3,000 USD. This efficiency maximizes available power for any space mission.

SatBat has been comprehensively tested for radiation tolerance and incorporates an integrated battery management system, ensuring consistent high performance and maintaining 98% capacity retention after a four-year low Earth orbit (LEO) mission.

With these advancements, SatBat is poised to redefine the space-rated battery market. No current Li-ion battery can match its combination of longevity, capacity, and weight efficiency.
