There aren't near as many updates to the batteries as the other equipment. The batteries aren't very complicated compared to the app, the drone and the controller. But, when there is one, remember that each battery is a separate device and each needs to be updated. I've known so few that I sometimes wonder if the update stays somewhere in the app or drone to apply to other batteries later. Good question, if that is possible. I don't remember a succession of battery updates as I put in another battery.
