Utah-based Electric Power (EP) Systems has confirmed that its legacy VersaPower battery system features on Archer’s Maker eVTOL demonstrator.
Details about the lithium-ion battery developer’s collaboration with Archer first emerged in June in the context of ongoing litigation between Archer and Wisk. In a declaration submitted by Archer’s attorneys, EP Systems CEO Nathan Millecam attested that his company began discussions with Archer in January 2020. Five months later, the parties entered into a development agreement that called for EP Systems to provide a “turn-key” solution for Archer’s high-power eVTOL battery system.
The version of the declaration filed in the public record is heavily redacted, with few details beyond the fact that the battery management units, battery modules, and cables provided to Archer are versions of EP Systems’ “already existing, off-the-shelf products.” Now, EP Systems has named those as VersaPower products — precursors to the EPiC family of lithium battery modules that it aims to certify with the Federal Aviation Administration for flight applications in 2022.
