I have a dji air 3 that I've had for a bit now and I use it probably once every 2 months. I got the fly more bundle with 3 batteries and the charger. When I do fly, the batteries are all at around 60% and I use the doc which charges all batteries to 100. If I do that but only use half of one battery, does that affect the battery health keeping the unused batteries all stored at 100? Surely there is an effective way to charge and use batteries for infrequent use. Thanks.
