Goodyear Ego2 Part 7 2017 Two batteries and new maps

Now we have two batteries and can go exploring on longer trips. We have also bought new maps for our neighborhood. New discoveries are waiting. Many small roads in the countryside are in a bad condition but Goodyear Ego2 can manage most of them if you adjust the speed. We have a big mountain area close and during descent I can roll without using the battery and still go rather fast for a long time. I don't know if the extra battery will lose power when it's not in use so I will check it before I start so I know how much power I have. The compartment for the extra battery is cramped and it's difficult to take the battery out from there, but it's easy to press the button and see how much power is left.
