Flew my DJI S1000+ with genace tattu 6S 22000mAh battery the other day. I have never pushed the battery to see what the longest safe flight time i could get was but am working my way to that point. I just loaded 3.4 rc1 and took it out. after about 13 minutes i heard the buzzer go off for failsafe and the GCS informed me the battery failsafe had triggered which I have set at 20.4 volts (3.4 volts/cell). It seemed a bit soon as I have gone a bit longer but I was doing an Autotune. When looking at the logs the lowest voltage recorded is 21.64 (3.606 volts/cell). I can not figure out why it triggered at the voltage it did. I am using a Mauch hall sensor for voltage and current that was supplied with a calibration report. So far the voltage and current readings have been ridiculously accurate. Even if the sensor was off, the logs dont match the specified failsafe voltage. Anyone have any ideas?
Thanks in advance for looking at it. If you have a chance to take a look at some other logged parameters I would appreciate it. I have never had a chance for anyone to look at my logs.
Even if the battery failsafe is not enabled (i.e. FS_BATT_ENABLE = 0) the “Low Battery” voltage threshold and “Reserved MAH” numbers are used to issue a battery warning
Thank you for your time and help in taking a look Bill. I feel a bit dumb now lol, i could have sworn it was set to 3.4v per cell or 20.4 volts total. Anyways thanks again for your support!
Sure, when get home I will post it again. It was straight from the pixhawk My logs are usually around 400mb and usually give me problems. I spoke to Mike Osborne? About this in the mission planner forum since I can not geotag images, I always get a log error but using ultra edit I see all looks as it should.
