Photography is an expensive hobby. Currently I have purchased a rather expensive technique for photography with which I can only work 25 minutes with one charge, but it is too short time, because often flying you see some good view, but I can't take it because the battery is low and then need to go home again charge a drone. In addition, 2 Batteries and car charger costs 379 EUR. I do not earn money with photography, but do it for my own and other people's joy. But in order to be able to take more photos and create more quality work, additional batteries are needed.
