With my P4, 3% equates to about 60 seconds of flying.. So 97% wouldn't necessarily be a big issue for me.. May be just fly it a minute longer than you would normally to compensate (if possible of course!)
That's about right. However, I assume you mean a minute
shorter than I normally would at 100%. The problem is that by the time the 97% battery is turned on and finally ready to fly, it's now down to 95%, after the IMU has warmed up, and the Home Point has been set. I fly with two external 2800 mAh batteries, which deliver up to a 30 minute flight time, so every minute lost on a 12 mile round trip flight is either a prime minute of photography/videography at my chosen remote location, or an extra margin of safety on the return flight, should I encounter a strong headwind on the return, or have lingered too long. On the P3, the battery can ALWAYS be topped off to 100%, even if you topped it off the night before. On the P4,
unless it is
already down to 95%, you CANNOT top off the battery, even though the instructions state to never fly without a
fully charged battery. It's annoying and
could potentially lead to a crash or water landing, where the bird would have otherwise have made it all the way home. Now I have to
manually discharge each of my batteries to 95%, just so I can then top them off to 100% before flying. This takes at least a half hour with three internal batteries.
