I have got this sensor and is attached to my battery , everything seems to work but I Arducopter didnt stop to use the power and now my battery is lower ( 5volts).
I did some research and I found a old guide saying to check FS_BATT_ENABLE that is 1 ( enable ), it wasnt!
Does Arducopter really cut the power if I arm the drone or spin motors when the voltage is low?
APM ver apm 2.5+ 3dr power module
Battery 4200 mah
I wont to throw away another battery so I want to make sure that it will not happen again
