So, I own two batteries for my vision+ and I'm getting about 20min per battery. Sometimes 40min of flying seems really short, and because of the charging time is so long, I started thinking "if I have 3 or 4, I'll always have one charged!" As the weather gets cooler, I would like to spend more time out too & since these batteries are not cheap, I thought I'll ask fellow Vision+ pilots. 1) how many batteries do you own? 2) how long do you fly when you go out?
