From the firmware notes... "New auto-discharging feature to address the issue of fully charged battery swelled when it was stored for an extended period." I'm all updated, including new battery firmware on two batteries and I can't see any control for auto discharging. Nothing in the Phantom Assistant software (3.2 or 3.4) Nothing that I can find in the Vision app. Nothing mentioned in the updated manual (Vision+ V1.6) Anyone have a clue? I assumed it would give us a way to charge to 50% or discharge down to 50% when we plan to store the battery. Maybe it's completely automatic if the battery is left fully charged for too long?
