142Wh of fly-safe batteries ready for takeoff whenever you are. AMPCells are the power behind the ride. 142Wh of interlocking, fly-safe batteries ready for takeoff whenever you are. Two AMPCells can generate 25kg of max thrust. A single AMPCell will generate less thrust. Each AMPCell comes with a number of stringent safety systems. These include an Advanced Battery Monitoring System, Phase Change Material for extended thermal headroom, a humidity sensor that detects any failure of the sealing architecture and sight glass for visually Identifying moisture in the event of a sensor failure.
