Yikes. That sounds unfun. When was the last time you calibrated your batteries? Uncalibrated batteries will exhibit large drops in the reported charge like this.
Can you please share share the synced flight log link in Maps Made Easy or at least let us know what your username is so we can take a look?
This isn't something we can cause (because that would be silly). We just listen for the reported battery values and display them. We had another user report something similar on the previous version. DJI updated the firmware versions last week and it has caused a bunch of weirdness. In order to stay functional with the new softwares we had to update the DJI SDK version we use in our app up to version 5.6.0. This may be a firmware related issue from DJI... Be sure to email them about it.
Are you 100% sure you did not have the DJI app running at the same time as Map Pilot Pro?
