Gulfstream Aerospace selected Securaplane’s lithium-ion battery as standard equipment on its new G650. The multimillion-dollar deal marks the first time a Gulfstream aircraft will feature the technology, which is some 50-percent lighter than conventional NiCad or lead-acid batteries and carries a higher energy density. The subsidiary of UK-based Meggitt said the weight reduction per shipset equates to nearly one passenger. The Securaplane system includes the main ship, emergency and flight control backup batteries with integral charging and control electronics.
