I may be able to explain why my Drone battery drains. They are brand new cells which has never been drained. And having the voltage drop in time isn't unusual before they start getting exercised. If this is why they have dropped, then none of my 250C drains the batteries. And service pack 35 isn't the latest, is it?I just checked, all 3 Paranormals and the Drones are running firmware 1.1 service pack 35 (all two cell). But all 3 Triades are running firmware 1.1 service pack 33 (all 3 cell). So that doesn't explain anything. Hardware version perhaps?
EDIT: I just placed a well used set of batteries in one Drone and we will see what happens.
EDIT2: Looks like service pack 38 is the latest.
