The internal battery of a normal action camera is not sufficient for the whole recording of the flight. With the help of this special Batterypack, it is possible to extend the battery power of your camera. The Batterypack, which is produced in Germany, differs from conventional Batterypacks mainly because of its high-quality and well-insulated battery cells. Compared to conventional batteries or power banks from the supermarket, this powerful Batterypack offers significantly more reliability at extreme temperatures, so that your camera reliably captures the entire flight even in case of extreme cold. The Batterypack, which is suitable for extreme activities, has a conventional USB port. The cable can be simply plugged into the micro/mini or USB-C port of the camera and switched on, thus extending the battery life for the stratospheric mission. In addition, the sustainable concept causes less electronic waste: if the battery performance decreases after numerous stratospheric flights, the battery can be easily replaced.
