Low Battery Warning is Different from Low Battery RTH Warning AND Critical Battery Warning.
Low Battery Warning simply tells you your battery is getting below a certain level of charge. The default setting is 30% but in the DJI Go app you can set it anywhere between 50% an 15%. You get some obnoxious beeping, and a soothing female voice telling you low battery, but other then that nothing.
Low Battery RTH (or as I like to call it "You Are Too Damn Far From Home For Your Battery!" warning) is triggered by a combination of how far you are away from your home point and what your altitude is at the time. The further and higher you are away from your Home Point the sooner or earlier Low Battery RTH will be triggered.
It can happen at 30% when you get the default low battery warning or anywhere between 30% (or higher) and 10% depending on how close/far you are from the home point.
Low Battery RTH warning gives you 10 seconds to cancel the RTH by stopping it on your Go app screen or hitting the RTH button on your RC. The default RTH behavior when triggered, is for the P3 to go straight up to the Failsafe altitude (30 meters by default), and then go directly to the home point and land. If the P3 is within 65 feet of the home point, when RTH starts, it will land where it is unless you cancel.
Critical Battery Warning is something completely different. If the battery gets below 10% the aircraft will give you a critical battery warning AND 10 seconds latter will start landing right where it is. The only way to override this (and it's not really an override) is to push the altitude control in the full up position and the aircraft with hold it's altitude long enough for you to take action to move the P3 horizontally to a safer landing area.
For instance, your over a pond and get Critical Battery Warning (Less then 10%). after 10 seconds the P3 start to descend (water or no water) to the pond. You hold your altitude control full up and it will maintain it's altitude while you move it to a dry landing area. As soon as you let go of the altitude control stick it will continue it's decent.
I've always felt that when you near 10% you are in a danger area anyway. I've only learned this from testing, testing, testing.
Hope this helps. |
