We acquired a 2nd EVO as a backup. The first one had original packaging so we used the EV5STDOR S/N. This EV5STDOR S/N worked for both the FAA and Autel product registration. However, the 2nd EVO has no original packaging and the only thing similar to a S/N I can find under the battery pack is an "IC" number which starts with 20910-EVO... This number works for FAA registration, but not in the Autel registration. In the absence of the original packaging, what S/N should be posted with the FAA registration? What with the Autel registration?
