Here a guide about how to store and travel with Mavic and Phantom Batteries. Including safety information, the use of decharger and lipo safety bags and the choose of the right charger.
I was sitting here thinking how do others on the forum store their Batteries.
Found your tread and thought I would reply and see if others chime in.
For me I have 2 in a case and the other in the drone.
For long time storage I think I will get those LiPo bags. At least there is some protection from a possible mishap.
