APM 2.5 power controller ? Where? How?

I've received my APM 2.5 kit and I find it has a cable that looks like it is for power control with two high current in-line yellow connectors and a fly-lead control wire.

I've done my best to read the instructions but I'm confused about where this cable fits in and where it should be plugged in.

Any advice appreciated. Especially any link to a definitive set-up page for this unit.

  • The new beta Wiki would be helpful to you but... that sounds like your power module.

    The high current connections put the unit in line with your battery and the power distribution board (for a multirotor) or the ESC (for an airplane/rover).

    The smaller connector goes to the APM and provides life support as well as voltage/current information.

    HERE is the page with the 'Power Port' indicated.

  • I forgot to mention that the existing build has an ECM and I assume that it plugs into the APM as the other servos do. The problem is how and why this new cable is to be used.
