MagniX launches batteries with over 1,000 full-depth discharge cycle capability


MagniX has introduced Samson, a battery line designed for aviation which it says delivers “industry-leading energy density” and “unmatched cycle life”.

Developed for applications that require high levels of performance, safety and reliability, Samson batteries will be certifiable under aviation regulations, according to magniX. The Samson300 is the first in the battery product line and focuses on maximising energy density for greater range and larger payloads.

 “magniX’s Samson batteries represent a breakthrough for magniX and electric aviation,” said Ben Loxton, vice president of Energy Storage Systems and the NASA Electric Powertrain Flight Demonstration Program at magniX. “With unrivalled energy density, cycle life, and safety features, magniX’s Samson batteries will help to unlock the tremendous potential of electric flight – enabling many eVTOLs and electric programs on the edge of viability to become viable.”  

When combined with magniX’s electric engines, the Samson batteries provide users with a fully integrated electric powertrain. Suitable for both battery- and hybrid-electric aircraft, Samson batteries are capable of powering helicopters, eVTOL aircraft and conventional aircraft. There are also use cases beyond aerospace, such as marine craft. 

 Key features include:

  • Energy density of 300 Watt hours per kilogram (Wh/kg)
  • Battery cycle life of over 1,000 full-depth discharge cycles to reduce operating costs
  • Patented safety technologies, including cell level protections from thermal runaway and ability to store batteries for long periods at zero charge
  • Fast aircraft turnaround time, with active on ground cooling during charging, and the option for passive cooling in flight
  • Integrated power electronics and distribution system 
  • Modular battery architecture to allow for simple replacement and powering larger aircraft
  • Designed for certification under aviation regulations.

“We are thrilled to introduce this revolutionary battery technology to the world of electric aviation and beyond,” said Reed Macdonald, CEO of magniX. “With the development of our Samson batteries, magniX can now offer customers a fully integrated electric powertrain, and it’s just the beginning. The roadmap to an energy density of 400Wh/kg or more is looking very promising. The future of flight is here, and it is being powered by magniX.”
