Does anyone know if there is a preferred way of connecting the APM Power Module and if ordering in reverse will damage any components?  I know one end is for LiPo while other is for ESC but no…Continue

"I need to obtain a new power module as mine is fried, as to why the one ESC was getting hot I moved onto a different project and haven't had a chance to retest with the new power module."

"I don't have PixHawk. I do have a PX4, which is an early PixHawk. I power it with 3DR power module."

"I am powering it through the 3DR Power Module, one side is coming from my PDB and the other the 4s LiPo battery.  I spoke with 3DR and they mentioned there should be no need for ANY red wires coming from any of the ESCs as that is an Output…"

"How are you powering the PixHawk? It sounds like the red wiring is powering the PixHawk. I had the similar setup on my APM and 1 ESC got hot. As long as it was flying it was ok. Sitting on the bench it would get really hot."

Issues with PixHawk, one ESC always hot on Quad

Since I setup my quad with the Pixhawk I've had issues and tried a series of things to rectify it.  I've pulled all red wires and taped them up coming from all 4 ESCs.  At that point the motors won't arm or spin up.  I plugged the Motor 1 red wire back in and all motors arms and spin up as expected.  After only a few seconds the one ESC that has its red wire connected heats up to the point of being extremely hot to the touch after no more than 10 seconds of low throttle.  In the last setup I…See More

"Hey Cody, I'm not using a TBS Discovery but a PDB no less.  In your setup in not using a BEC did you remove all but one of the four ESC positive and negative wires from the ESCs?  I'm not understanding why a BEC would be…"

"The batteries would have come with correct connector preinstalled. So fix the matching connector to device you like to install.  Like T.Buttler  pointed out, the reasoning for "why" is  common sense and bit of safety. …"

"Always appreciate the why, makes perfect sense.  It appears as though I should order up more XT60s.  If I had this framework to begin with I wouldn't have spent so much money on them, someone is making my money I'm…"

"That I do know, however I was unaware that there was an industry standard in terms of what is to be connected to the male and female ends for XT60."

"If you look closely on the XT60's you will see a + and a - on the corresponding terminals.Please be very careful soldering as shorting out the battery terminals may lead to a fire in LiPo batteries if not caught quickly."

"@_leff, Reversing the battery and ESC connection will damage the PM. Do not do that! The XT-60 connectors on each end of the PM are industry standard configurations. If you have batteries and ESCs with reversed XT-60 connectors, then you have not…"
