What GS Yuasa Lithium Power does

GS Yuasa Lithium Power (GYLP) is the North American arm of GS Yuasa's space battery business, established in 2006 and headquartered in Roswell, Georgia, with cell manufacturing performed at the parent company's Kyoto, Japan facility. The company designs and supplies high-reliability lithium-ion cells and battery systems purpose-built for spacecraft, based on a proprietary LCO/Graphite chemistry refined across four generations over more than 15 years. Its product portfolio spans large-format LSE cells (51Ah to 205Ah, in energy- and power-optimized variants) for GEO, MEO, LEO, and human-rated programs, plus the compact LSE12x cell and scalable MA12x modular platform (720Wh to 4,320Wh) targeting the smallsat and LEO constellation market.

GYLP operates a direct enterprise sales motion led by U.S.-based power systems engineers who provide mission analysis, trade studies, and configuration support to spacecraft primes, integrators, and new-space customers under NDA and ITAR/EAR controls. Revenue is generated through quote-based hardware sales of cells and battery platforms, supplemented by engineering services tied to mission modeling and qualification support. The company sells to a concentrated set of aerospace and defense customers — disclosed names include Northrop Grumman, NASA, and EaglePicher Technologies — and reports cumulative flight heritage of more than 5 MWh across 262+ satellites and 550+ million cell-hours, with zero cell failures on major programs.

The business is differentiated by flight-proven long-duration performance (20+ years on orbit, e.g., Thaicom 4), configuration stability across cell generations enabling heritage carry-over, proprietary life and performance modeling tools, and AS9100/ISO 9001 certification across both the Kyoto manufacturing and Roswell integration/test sites. The current strategic focus is on commercializing the Generation 4 chemistry with North American partners and extending the same trusted electrochemistry into the fast-growing smallsat and constellation segment via the MA12x platform.

Core offering

GS Yuasa Lithium Power manufactures and supplies high-reliability lithium-ion batteries and modular battery systems for space applications. Their portfolio includes large-format LSE cells (Gen 3 and Gen 4) built on LCO/Graphite Li-ion chemistry for large spacecraft across GEO, MEO, LEO, and human-rated programs, as well as the compact LSE12x cell and the MA12x modular battery platform designed for smallsat and constellation programs. The company also provides direct US-based mission analysis and engineering support from its Roswell, GA office, with manufacturing performed in partnership with parent company GS Yuasa in Kyoto, Japan.

Product overview

GS Yuasa Lithium Power offers a portfolio of high-reliability lithium-ion batteries for space applications, consisting of two main product lines: large-format LSE cells for large spacecraft (available in Gen 3 and Gen 4 variants with capacities from 51Ah to 225Ah), and the compact LSE12x cell combined with the scalable MA12x modular platform for smallsat and constellation programs (720Wh to 4,320Wh). All products share the same LCO/Graphite chemistry and manufacturing processes developed in GS Yuasa's Kyoto facility, with over 5 MWh flown across 262+ satellites with zero cell failures.

Products and services

• Large-Format LSE Cells (Gen 3 and Gen 4) High-reliability space-grade lithium-ion cells built on Gen-4 LCO/Graphite chemistry in a large-format wound-prismatic construction; designed for large spacecraft programs including GEO, MEO, LEO, and human-rated missions, with 25+ years of flight heritage.
• LSE12x Cell Compact lithium-ion cell built on the same Gen-4 LCO/Graphite chemistry as the large-format LSE line; targeted at smallsat and constellation programs requiring the same flight-proven space-grade performance in a smaller form factor.
• MA12x Modular Battery Platform Modular battery platform built around the LSE12x cell, providing flexible, scalable battery system configurations for smallsat and constellation customers needing adaptable power system architectures.
• Mission Analysis and Engineering Support Direct US-based engineering services including mission analysis, life and performance modeling using proprietary tools validated against flight data, and ongoing technical engagement with spacecraft integrators and constellation operators.
