The PixHawk along with Mission planner allows us to set battery thresholds and we can make a Quad or plane to do RTL, land etc. if the battery voltage drops below predefined thresholds.
I am wondering if there is an external battery cut of a system that can stop the battery from draining below certain per cell voltage to maximize the battery life for 4S to 6S + Lipo's?
I saw one device on eBay called "Lipo shield"
Not ordered it yet, but wondering if anyone has used any other devices in the past with similar feature functionality and designed for 6S @ 10,000 mAH and higher.
