Just make it like all the competition pilots with their gasoline ppg. you fly yourself with the airplane. the ppg lets you ship with ups, dhl or what is cheapest to your holiday address. calculate the runtime with packet service. You have the advantage that you can insure everything against loss and theft. that is not so possible in the plane. This transport solution has long been proven and works. At the time, I had a competitor transport his batteries and e-ppg to Austria. it is important to attach the eu safety mark to the battery at the packet. You can search and print this on the internet. certainly the transport will cost 150 to 200 euros. But if you have money and time for vacation is not a problem. It’s a luxury event, not an everyday event. 99.9% pilots always travel with ppg by car or caravan. In Europe, flying with 4 motors is prohibited in most countries. Please note this in your planning.
