when I fly my quadcopter and the battery gets low the APM stops receiving commands and, the quadcopter continues to hover in fact it goes slightly high about 10 meters then it stays there until the battery runs out.
I have only tested my quadcopter twice and this happened twice, the first time it did my quadcopter ended up 15 meters high on a tree I replaced the board after that incident and used another brand new APM and today as I was flying it and around 25min into the flight just when the low voltage alarm started beeping I suddenly lost control and quad went slightly high around 10 meters then kept hovering until it landed and the props were off so I quickly ran to the quad to disconnect the power but suddenly it started working again but I managed to unplug it "one of the props managed to hit my hand "
the transmitter has new batteries and its working as it should be, this issue is really bothering me
I am powering the APM using a power module and the receiver is powered from the apm, the battery voltage never went below 10.4v its a 3S Lipo.
the version is V3.1.5
your help and advice is much appreciated
