I have a Nikon camera with a pair of Godox TT685N speed lights. I got the opportunity to get a couple of Nikon speed light battery packs for next to nothing. Godox uses Canon power ports for all their flashes. I hate throwing away perfectly good battery packs, but somehow I have to convert that male Nikon plug into a male Canon plug. But I don't have the pinout information and my Googling lead me to battery pack vendors. :)

So, I did find the Canon info: GND and +300V pins have an obstruction between them. I just need the Nikon info now, and then source a Canon plug.

  • What is the model number of the battery packs?

It turns out that the Nikon connections are all (relatively) low voltage. There is no 300V output, which the Canon connection requires. To use the power supply, I'd have to manufacture a hole in the battery door and wire it up to the battery connections. I won't be doing that.

For future reference, just know that Godox uses Canon connections on all of their speed lights, so get a Canon style power pack if you want an auxiliary power pack.
