Hello, I’m back
Recently I connected my LiPo to my PDB and ESCs. As soon as the male XT60 plug (on the battery) contacted the female side (on the PDB), a blue spark jumped out of the plugs! People say that’s normal, and I think if I had touched any connections on that board or the wires, I would have been dead. I had all four motor + ESC pairs connected on the board. Now I’m worried because I think I fried my ESCs, although I’m not too sure. The second time I attempted to plug in the battery (this time with only one of the motors and ESC), one of the bullet connectors on a wire on the board touched one other, and burnt each other! The motor didn’t even move nor did the ESC beep the way I think it should have.
My ideas about what the problem may be is that:
- The solder joints on the PDB are shorting each other (not sure if flux conducts electricity)
- The LiPo is shorted inside or the plugs are color insulated wrongly
Lastly, a LiPo should have NO current running at all, unless an ESC “asks” for it, right? And ESCs should beep when the battery is connected to the leads, or when the servo wire is connected to a 5v source (like Arduino), or both?
Sorry for lengthy words
