I have more things to keep charged on the vision 2+ than I would like. I really do not want something else to charge. It seems like someone should have a tracker that is charged by (not to be confused with powered by) the Phantom battery. I will probably add a Flytrex in the future but even though they talk about never lose your phantom again, it really doesn't seem like a viable option. I assume if you lose connectivity with the Phantom and it happened to fly away (for whatever reason) then the Flytrex is not relaying data.
