What should I pay attention to when driving an electric car and running a long distance?

I also run long distances. I don't know if you are a two-wheeled vehicle or a tricycle. I am a tricycle. First of all, I use more than two sets of batteries (the batteries are more powerful). If possible, I can add a range extender and solar panels with a little repair tools. I ran a little more than 65438+100000, and I don't have much experience at present. I'll talk to you later. Where are you? You can add me to WeChat-
