I am going to throw my 2 cents in here. Industrial electrician for 10 years, working with 2VDC all the way to 138kvac. Whenever we disconnect / reconnect a DC circuit we always always always connect the hot then the ground, and when we disconnect we remove the ground first then the hot.
I am not telling you to do this on your expensive multirotor but it's what I plan to do. If you do this I do not see any way, shape or form as to how it would somehow damage your multirotor unless your motors were armed when you plugged the battery in (which they should not be for "inrush" purposes). The reasoning for doing this is to prevent arcing, which if your ground is on and you connect your hot there is always a chance to arc, if your hot is connect first and you connect your ground and there is an arc (always a chance) it will go to ground, that's why it's there. |
