That is odd. There is a battery failsafe at what looks like the FS_BATT_VOLTAGE threshold (12.8) despite the fact that the battery failsafe is disabled. Did it RTL though? There isn’t an RTL mode logged just the low battery failsafe then a change to PosHold.
The return was programmed into the mission. The error didn’t interrupt the mission though. The previous time this happened, it did RTL on its own while I was flying around manually. If I had been under a tree or whatever, it would have been bad.
