Electric Power Systems (EP Systems) this week launched its new Epic family of electric batteries for aircraft. The U.S. company aims to get approval for the three battery modules under a FAA and EASA technical standard orders by the second quarter of 2022 and says they will be suitable to power eVTOL and electric fixed-wing aircraft of various sizes, including existing models that could be retrofitted.

The new Epic battery family consists of the Energy, Power, and Ultra modules. All feature thermal runaway safety protection against overheating and a packaging overhead amounting to between 20 and 25 percent of the battery’s modular mass. The Energy and Power units are designed for a service life of over 2,000 cycles, based on an 80 percent depth of discharge rate, while the Ultra is projected to reach 7,500 cycles.
